CVE-2025-25789 is a critical-severity Code Injection (CWE-94) vulnerability in Foxcms Foxcms. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 33% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

FoxCMS version 1.2.5 contains a remote code execution vulnerability in the index() method of the Sitemap.php controller file. The flaw is tracked as CVE-2025-25789 and is associated with CWE-94. It received a CVSS 3.1 base score of 9.8, reflecting network attack vector, low complexity, and no requirements for authentication or user interaction.

An unauthenticated attacker with network access can supply crafted input to the affected method and execute arbitrary code on the server, resulting in full compromise of confidentiality, integrity, and availability. The published references consist of the vendor site and a public proof-of-concept repository that demonstrates the issue.

EPSS for the CVE rose from a low baseline to a recorded peak of 0.0411 (current value 0.0227), indicating emerging exploitation interest after disclosure. No vendor advisory or patch information is provided in the available references.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
