Description
Remote code execution that allows unauthorized users to execute arbitrary code on the server machine.
Analysis
Critical remote code execution vulnerability with a perfect CVSS 10.0 score that allows unauthenticated attackers to execute arbitrary code on affected servers over the network with no user interaction required. The vulnerability stems from improper handling of code evaluation (CWE-94: Improper Control of Generation of Code) and affects systems processing untrusted input. Given the maximum CVSS severity, network attack vector, and lack of authentication requirements, this vulnerability represents an immediate and severe threat to any exposed systems and should be treated as a critical priority for patching regardless of additional context.
Technical Context
This vulnerability is rooted in CWE-94 (Improper Control of Generation of Code), which encompasses unsafe code evaluation, dynamic code execution, and deserialization vulnerabilities. The attack vector is network-based (AV:N) with low complexity (AC:L), indicating the flaw can be triggered through standard network protocols without requiring special conditions. The vulnerability affects the code generation or interpretation layer of affected software, likely through unsafe eval() functions, unsafe deserialization, template injection, or expression language injection mechanisms. Without specific CPE data provided, the vulnerability likely affects multiple versions of a widely-deployed application or library. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C indicates network accessibility, no privilege escalation requirement, no user interaction needed, and scope change indicating impact beyond the vulnerable component.
Affected Products
Specific product names and version numbers cannot be determined from the provided CVE description alone, as no CPE identifiers, vendor names, or product references are included in the available data. However, the vulnerability's characteristics (network RCE, code evaluation flaw, CWE-94) suggest it likely affects: web application servers or frameworks with template engines, dynamic code execution capabilities, or expression language processors; application servers that deserialize untrusted data; or libraries used for code generation or scripting. Organizations should: (1) Check their security advisories and vendor notifications for CVE-2025-29902; (2) Scan their infrastructure for any products matching the profile of CWE-94 vulnerabilities; (3) Review recent security bulletins from their software vendors; (4) Contact vendors directly if CVE applicability is unclear. Without CPE data, comprehensive affected product mapping is not possible—vendor advisories are essential.
Remediation
Immediate remediation steps: (1) URGENT: Apply security patches from affected vendor(s) as soon as they become available—do not delay implementation; (2) If patches are unavailable, implement immediate compensating controls: disable or restrict network access to affected services using firewalls/WAF rules, implement network segmentation to limit exposure, disable dynamic code execution features if configurable; (3) Monitor systems for signs of exploitation (unusual process execution, network connections from unexpected sources, code generation activities); (4) Implement input validation and sanitization to reject suspicious payloads attempting code injection; (5) Deploy web application firewalls (WAF) with signatures for CWE-94 exploitation attempts; (6) Review and restrict code evaluation functionality—prefer safe alternatives like domain-specific languages or sandboxed execution; (7) Conduct incident response readiness review given RCE risk; (8) Prioritize this above all other patching activities.
