Remote Code Execution
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
How It Works
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access. Unlike a single vulnerability class, RCE is an outcome—the catastrophic result of exploiting underlying weaknesses in how applications process input, manage memory, or handle executable content.
Attackers typically achieve RCE by chaining vulnerabilities or exploiting a single critical flaw. Common pathways include injecting malicious payloads through deserialization flaws (where untrusted data becomes executable objects), command injection (where user input flows into system commands), buffer overflows (overwriting memory to hijack execution flow), or unsafe file uploads (placing executable code on the server). Server-Side Template Injection and SQL injection can also escalate to code execution when attackers leverage database or template engine features.
The attack flow usually begins with reconnaissance to identify vulnerable endpoints, followed by crafting a payload that exploits the specific weakness, then executing commands to establish persistence or pivot deeper into the network. Modern exploits often use multi-stage payloads—initial lightweight code that downloads and executes more sophisticated tooling.
Impact
- Complete system compromise — attacker gains shell access with application privileges, potentially escalating to root/SYSTEM
- Data exfiltration — unrestricted access to databases, configuration files, credentials, and sensitive business data
- Lateral movement — compromised server becomes a beachhead to attack internal networks and other systems
- Ransomware deployment — direct pathway to encrypt files and disable backups
- Persistence mechanisms — installation of backdoors, web shells, and rootkits for long-term access
- Supply chain attacks — modification of application code or dependencies to compromise downstream users
Real-World Examples
The n8n workflow automation platform (CVE-2024-21858) demonstrated how RCE can emerge in unexpected places-attackers exploited unsafe workflow execution to run arbitrary code on self-hosted instances. The Log4j vulnerability (Log4Shell) showed RCE at massive scale when attackers sent specially crafted JNDI lookup strings that triggered remote class loading in Java applications worldwide.
Atlassian Confluence instances have faced multiple RCE vulnerabilities through OGNL injection flaws, where attackers inject Object-Graph Navigation Language expressions that execute with server privileges. These required no authentication, enabling attackers to compromise thousands of internet-exposed instances within hours of disclosure.
Mitigation
- Input validation and sanitization — strict allowlists for all user-controlled data, especially in execution contexts
- Sandboxing and containerization — isolate application processes with minimal privileges using containers, VMs, or security contexts
- Disable dangerous functions — remove or restrict features like code evaluation, system command execution, and dynamic deserialization
- Network segmentation — limit blast radius by isolating sensitive systems and restricting outbound connections
- Web Application Firewalls — detect and block common RCE patterns in HTTP traffic
- Runtime application self-protection (RASP) — monitor application behavior for execution anomalies
- Regular patching — prioritize updates for components with known RCE vulnerabilities

Apache OpenNLP's model loading mechanism executes arbitrary static initializers through crafted manifest entries, enabling attackers to trigger side effects in any classpath class before type validation occurs. Affects OpenNLP versions before 2.5.9 and 3.0.0-M3. While not direct RCE, exploitation becomes viable when third-party models from untrusted sources (community repositories, model-sharing platforms) are loaded in environments containing classes with JNDI lookups, network I/O, or filesystem operations in static initializers. EPSS score of 0.29% suggests low widespread exploitation probability despite CVSS 9.8, though attack surface grows with model-sharing ecosystem adoption. No public exploit identified at time of analysis; vendor-released patches available.
Remote code execution in Notesnook Desktop (Electron-based) via stored XSS in the note export-to-PDF flow allows unauthenticated remote attackers to execute arbitrary code when a user opens a maliciously crafted note. The vulnerability stems from unescaped HTML in exported note fields (title, headline, content) that execute in an Electron iframe with nodeIntegration enabled and contextIsolation disabled, escalating browser-based XSS to full RCE. Affects Notesnook Web/Desktop <3.3.15 and iOS/Android <3.3.20. CVSS 9.6 with changed scope (S:C) reflects privilege escalation from browser context to system-level code execution. EPSS and KEV data not provided, but requires user interaction (UI:R) to export/view the malicious note, limiting automated exploitation.
Full sandbox escape with arbitrary code execution allows remote attackers to break out of vm2's Node.js sandbox environment (version 3.10.4) and execute commands on the host system. Attacker-controlled code running inside VM.run() can obtain the host process object and execute arbitrary host commands without any cooperation from the host application. EPSS data not available, but this represents complete failure of the sandbox security boundary. Patch released in version 3.10.5 addresses eleven distinct escape vectors including Function constructor leakage, proxy unwrapping, util.inspect exposure, and WebAssembly exception handling.
Sandbox escape leading to remote code execution in the vm2 Node.js sandbox library affects all versions prior to 3.11.0, where the JavaScript SuppressedError mechanism (combined with DisposableStack disposal) lets untrusted code running inside the sandbox reach a host constructor and execute arbitrary commands on the underlying server. Any application that relies on vm2 to safely run attacker-controlled or untrusted JavaScript is fully compromised, with a working proof-of-concept published in the GHSA advisory. There is publicly available exploit code but no confirmed active exploitation; the SSVC framework rates it POC, automatable, with total technical impact, while EPSS remains low at 0.06%.

Attackers can exploit inadequate input validation in the hex_to_binary function affecting PKZIP hash parser modules (17200, 17210, 17220, 17225, 17230) to overflow fixed-size buffers with arbitrary hex data. CVSS 9.8 reflects network-accessible attack vector requiring no authentication or user interaction, though real-world exploitation requires victim to process attacker-supplied hash files. EPSS data not available; no CISA KEV listing indicates no confirmed widespread exploitation. Public proof-of-concept exists (GitHub Gist), elevating exploitation risk for environments processing untrusted hash files.
Heap-based buffer overflow in hashcat 7.1.2's Kerberos hash parser enables remote code execution without authentication. Attacker supplies a maliciously crafted Kerberos hash file with manipulated delimiter positions to overflow the fixed-size account_info buffer during memcpy operations in module_hash_decode. The vulnerability affects multiple Kerberos-related hashcat modules due to missing upper-bound validation on account_info_len before memory copy. CVSS 9.8 with network attack vector, but real-world exploitation requires user processing the malicious file. EPSS data not available; no active exploitation confirmed in CISA KEV at time of analysis.
Stack-based buffer overflow in hashcat 7.1.2's rule processing functions enables remote code execution when processing password candidates of 128+ characters. The vulnerability stems from inadequate bounds checking in mangle_to_hex_lower() and mangle_to_hex_upper() functions that fail to account for 2x memory expansion during byte-to-hex conversion. CVSS 9.8 (critical) with network attack vector and no authentication required. Public proof-of-concept code available via GitHub gist. No CISA KEV listing suggests targeted rather than widespread exploitation despite theoretical network exploitability.

No active exploitation confirmed in CISA KEV, but proof-of-concept details available via GitLab issue tracker. EPSS data not available for risk prioritization.
Remote code execution in HKUDS OpenHarness allows authenticated remote attackers to execute arbitrary operating system commands via the /bridge slash command. Attackers with remote sender privileges can invoke '/bridge spawn' with malicious command arguments that bypass input validation and execute directly through the shell subprocess helper, granting access to local files, credentials, workspace state, and repository contents. Vendor-released patch available (commit 438e373) that restricts /bridge to local-only invocation by default.
Remote code execution in IBM Langflow Desktop 1.0.0 through 1.8.4 allows authenticated attackers to execute arbitrary commands at the privilege level of the Langflow process. Attackers can exfiltrate API keys and database credentials from environment variables, modify application files, or pivot to internal network targets. IBM has released a vendor patch addressing this code injection vulnerability. No active exploitation confirmed by CISA KEV at time of analysis, though CVSS 8.8 severity and low attack complexity indicate high exploitability once authenticated access is obtained.
Argument injection in Gotenberg v8.30.1 and earlier allows unauthenticated remote attackers to manipulate filesystem operations by embedding newline characters in PDF metadata values. The vulnerability bypasses an incomplete fix from v8.30.1 that sanitized only metadata keys while leaving values unvalidated, enabling injection of ExifTool pseudo-tags like -FileName, -Directory, -SymLink, and -HardLink through the /forms/pdfengines/metadata/write endpoint. Attackers can move files to arbitrary paths (including overwriting /etc/passwd), create symlinks for read/write primitives, and persist data via hard links - all without authentication against default configurations. Vendor-released patch: version 8.31.0. CVSS 10.0 severity reflects the network attack vector (AV:N), no authentication requirement (PR:N), low complexity (AC:L), and scope change (S:C) enabling container escape scenarios. No public exploit identified at time of analysis, though complete PoC reproduction steps are documented in GitHub advisory GHSA-q7r4-hc83-hf2q.
Stored XSS in Jupyter Notebook's CommandLinker feature enables authentication token theft through malicious notebook files, leading to complete account takeover. Attackers craft notebook files with disguised controls that, when clicked once by victims, execute arbitrary code via the Jupyter REST API, granting full filesystem access and kernel control. Reported by NVIDIA AI Red Team. Vendor-released patches available: Jupyter Notebook 7.5.6 and JupyterLab 4.5.7. No public exploit code identified at time of analysis, but proof-of-concept demonstrated internally by NVIDIA researchers. This vulnerability targets data science and ML engineering environments where notebook sharing is common practice.

Rated critical severity (CVSS 9.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
Remote code execution in Synway SMG Gateway Management Software allows unauthenticated attackers to execute arbitrary OS commands via command injection in the RADIUS configuration endpoint. The vulnerability exploits unsanitized POST parameters (radius_address, radius_address2, shared_secret2, source_ip, timeout, retry) that are directly interpolated into sed commands at /en/9-2radius.php. Shadowserver Foundation confirmed active exploitation beginning July 11, 2025, with publicly available exploit code and Nuclei templates enabling widespread automated attacks. CVSS 9.3 critical severity reflects the combination of network accessibility, zero authentication requirements, and complete system compromise potential.
Code injection in Qt SVG module allows attackers to execute arbitrary QML/JavaScript when applications load malicious SVG files through Qt Quick's VectorImage component. Exploitation requires local file access and user interaction (opening crafted SVG). While QML execution is more restricted than native code, attackers can still trigger denial of service, exfiltrate application data, or manipulate UI logic depending on the victim application's privilege context. No active exploitation confirmed (not in CISA KEV), but patch available from Qt Project reduces urgency for immediate emergency response.
Heap buffer overflow in FreeBSD dhclient enables potential remote code execution when processing maliciously crafted DHCP packets. Affects FreeBSD 13.5, 14.3, 14.4, and 15.0 branches prior to security patches. EPSS exploitation probability is low (0.03%, 8th percentile) and no active exploitation confirmed, but SSVC classifies this as automatable with partial technical impact. The vulnerability requires network position to send crafted DHCP responses (CVSS AV:N/AC:H), making exploitation complexity high but not requiring authentication.
Remote code execution as root in FreeBSD dhclient allows malicious DHCP servers to inject arbitrary commands via unsanitized BOOTP file field in DHCP responses. When dhclient writes lease data without escaping embedded double-quotes and later re-parses it (e.g., after system restart), injected dhclient.conf directives execute through dhclient-script. EPSS score is notably low (0.02%, 5th percentile) with SSVC indicating no observed exploitation and partial technical impact, suggesting limited real-world targeting despite the high-severity nature of root code execution. No public exploit code identified at time of analysis.

The project was informed of the problem early through an issue report but has not responded yet.
Jenkins Credentials Binding Plugin 719.v80e905ef14eb_ and earlier does not sanitize file names for file and zip file credentials, allowing attackers able to provide credentials to a job to write files to arbitrary locations on the node filesystem, which can lead to remote code execution if Jenkins is configured to allow a low-privileged user to configure file or zip file credentials used for a job running on the built-in node.
Ollama for Windows contains a Remote Code Execution vulnerability in its update mechanism due to improper handling of attacker‑controlled HTTP response headers. When downloading updates, the application constructs local file paths using values derived from HTTP headers without validation. These values are passed directly to filepath.Join, allowing path traversal sequences (../) to be resolved and enabling files to be written outside the intended update staging directory. An attacker who can influence update responses can exploit this flaw to write arbitrary executables to attacker‑chosen locations accessible to the current user, including the Windows Startup directory. This allows execution of arbitrary executables. Critically, when chained with CVE‑2026‑42248 (Missing Signature Verification for Updates), an attacker can deliver malicious payloads that are written to sensitive locations and executed automatically. Because Ollama for Windows performs silent automatic updates and executes staged binaries without user interaction, this results in automatic and persistent code execution without user awareness. Maintainers of this project were notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Versions from 0.12.10 to 0.17.5 were tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.
Remote code execution in Cockpit CMS versions 2.13.5 and earlier allows unauthenticated attackers to execute arbitrary system commands on the server by injecting malicious payloads through the filter parameter across multiple endpoints. The vulnerability exploits the MongoLite database layer's $func operator, which processes user-controlled input as executable code. Public proof-of-concept exists and the attack is fully automatable with total system compromise potential, though EPSS scoring suggests limited observed exploitation attempts (2nd percentile) at time of analysis.
B1 Free Archiver v1.5.86 strips Mark of the Web (MotW) protections from files extracted from internet-downloaded archives, allowing untrusted executables to run without Windows Defender SmartScreen warnings. Attackers can deliver malware via email attachments or malicious downloads that, when extracted using this archiver, bypass Windows security prompts entirely. EPSS exploitation probability is minimal (0.01%) with no active exploitation or public POC identified, suggesting limited real-world targeting despite the 7.3 CVSS score and theoretical RCE capability.
Remote code execution in Cockpit CMS 2.13.5 and earlier allows authenticated users with low privileges to execute arbitrary PHP code on the server. Attackers exploit a filter bypass in the Bucket component's _isFileTypeAllowed function by crafting filenames that evade extension validation, then renaming files to .php for execution. Public proof-of-concept exists (SSVC: poc). EPSS data unavailable, but CVSS 8.8 with network vector and low attack complexity indicates high exploitability once authenticated.
