Missing authentication for a critical device function in Dell ThinOS 10 (all versions prior to SecurityAddon_2605.10.2766_T10) allows an unauthenticated remote attacker who can reach the exposed function to gain unauthorized access to it, reflected in a CVSS:3.1 base score of 8.6 under the vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:L, where the high integrity impact dominates and confidentiality and availability effects are limited. No public exploit code and no confirmed active exploitation were identified at time of analysis, so this is a genuine priority signal rather than a confirmed-exploited emergency. The main practical constraint on exploitation is network reachability: ThinOS endpoints are typically deployed inside enterprise/VDI network segments rather than exposed to the public internet, so meaningful risk arises when an attacker already has a foothold on a segment from which the affected service can be reached.
Improper TLS certificate validation in Dell ThinOS 10 endpoints running SecurityAddon builds prior to 2605.10.2766_T10 lets an adjacent-network attacker bypass a protection mechanism and gain unauthorized access to client communications and credentials. The flaw is rated CVSS 8.3 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L), meaning no authentication or user interaction is required, but the attacker must already sit on the same Layer-2 segment, VLAN, or Wi-Fi network as the thin client to position themselves for a machine-in-the-middle interception. No public exploit code has been identified at time of analysis and the issue is not listed in CISA KEV, so this is a genuine elevated-priority issue rather than an emergency - the practical risk is driven by how flat and trusted the thin-client network segment is.
Arbitrary code execution in Dell ThinOS 10 (all builds prior to 2605_10.2616) allows a remote, unauthenticated attacker to run code within the application context of the affected thin client, per Dell advisory DSA-2026-389. The root cause is a protection mechanism failure (CWE-284) that bypasses an intended security control rather than exploiting a memory-corruption bug directly. No public exploit is identified at time of analysis and the CVE is not in CISA KEV, but the network-reachable, no-authentication attack profile makes it high priority.
Authenticated remote command execution in Dell ThinOS 10 (builds prior to 2605_10.2616) allows an attacker who already holds high administrative privileges on the device to inject OS commands into a privileged management function, achieving command execution with high confidentiality, integrity, and availability impact. The assessed vector (CVSS 7.2, AV:N/AC:L/PR:H/UI:N) means the flaw is not reachable by an anonymous remote attacker and is not automatable per CISA SSVC, which records no exploitation activity; no public exploit code was identified at time of analysis. EPSS sits at a moderate 2.28% (82nd percentile), consistent with a privilege-gated issue rather than a mass-exploitation emergency.
Remote code execution in Dell ThinOS 10 (versions prior to 2605_10.2616) allows an unauthenticated remote attacker to inject and execute arbitrary OS commands via improper neutralization of special elements in a command context (CWE-78). Dell released the vulnerability itself (DSA-2026-389) and a fixed build is available; there is no public exploit identified at time of analysis and the CVE is not on CISA KEV.
Remote code execution in Dell ThinOS 10 (all versions prior to 2605_10.2616) allows an unauthenticated attacker who already sits on the same logical or physical network segment as the thin client to run arbitrary commands on the device. No credentials and no user interaction are required, and the vendor CVSS 3.1 vector scores it 8.8 (High) with full confidentiality, integrity and availability impact, but the adjacent (AV:A) attack vector means it is not reachable from the general internet or across routed boundaries by default. There is no public exploit identified at time of analysis and no CISA KEV listing; EPSS is 1.29% (69th percentile), CISA's SSVC assessment rates exploitation as 'none' and automatable as 'no', and Dell has published a fix via advisory DSA-2026-389.
Improper access control in Dell ThinOS 10 (all versions prior to 2605_10.2518) enables a local low-privileged user to bypass access restrictions and gain unauthorized access to protected resources on the affected thin client system. The CVSS score of 7.8 (High) reflects complete confidentiality, integrity, and availability impact upon successful exploitation, despite requiring only local, low-privilege access with low attack complexity. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in CISA KEV.
Unauthorized access in Dell ThinOS 10 (versions prior to 2605_10.2100) stems from an obsolete UI feature (CWE-448) that a low-privileged local attacker can abuse to bypass authentication controls. With valid low-level local access to the thin-client, an attacker can leverage the leftover interface path to reach functionality or data they should not have, yielding high confidentiality, integrity, and availability impact per the CVSS 7.8 (High) rating. No public exploit identified at time of analysis; the flaw was reported by Dell and disclosed in advisory DSA-2026-300.
Local privilege escalation in Dell ThinOS 10 versions prior to ThinOS10 2602_10.0765 allows a low-privileged user with local access to elevate to higher privileges due to improper access control (CWE-284). The CVSS 3.1 base score of 7.8 reflects high impact on confidentiality, integrity, and availability, though exploitation requires existing local foothold. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Arbitrary code execution in Dell ThinOS 10 (all builds prior to 2605_10.2616) is enabled by a missing integrity check (CWE-353) that allows a local high-privileged attacker to substitute unverified code or data in a load path the OS processes without cryptographic validation. Dell advisory DSA-2026-389 confirms both the vulnerability and a corrective update. No public exploit code or CISA KEV listing exists at time of analysis, limiting real-world risk to targeted insider-threat or physical-access scenarios.
Dell ThinOS 10 firmware allows a low-privileged attacker with physical device access to overwrite the Security Version Number (SVN) with an older value, enabling a downgrade rollback to earlier firmware versions that lack current security protections. All releases prior to 2605_10.2616 are affected. By reverting the device to a prior vulnerable firmware state, an attacker can bypass protection mechanisms enforced in newer firmware - including security controls, hardening measures, or patched vulnerabilities - achieving full confidentiality, integrity, and availability compromise of the thin client.
Arbitrary code execution on Dell ThinOS 10 (all versions prior to 2605_10.2616) is possible when an unauthenticated attacker gains physical access to a thin client endpoint and exploits the absence of cryptographic integrity verification during code download (CWE-494). The vulnerability allows substitution of a malicious payload during the device's update or provisioning process, resulting in full system compromise with high confidentiality, integrity, and availability impact. No public exploit code and no CISA KEV listing have been identified at time of analysis; the physical access prerequisite (AV:P) substantially constrains the attacker population.
Protection mechanism failure in Dell ThinOS 10 (versions prior to 2605_10.2100) allows an unauthenticated attacker with physical device access to bypass encryption controls and gain unauthorized read and write access to data stored on the thin client. The flaw, classified as CWE-693, indicates the encryption or authentication protection subsystem can be circumvented without any credentials, consistent with the Authentication Bypass tag and CVSS PR:N rating. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog, though the physical access constraint limits but does not eliminate risk in environments with unattended or theft-prone thin clients.
Physical access to Dell ThinOS 10 endpoints running versions prior to ThinOS10 2602_10.0765 allows an unauthenticated attacker to bypass access controls, exposing sensitive information with high confidentiality and integrity impact. The flaw, rooted in CWE-284 (Improper Access Control), enables circumvention of authentication or authorization mechanisms at the device level without requiring prior credentials. No active exploitation has been confirmed (not in CISA KEV) and no public exploit has been identified; Dell has released a patched build addressing this issue.
