Summary

CVE-2025-70073 is a high-severity Code Injection (CWE-94) vulnerability in 1000Mz Chestnutcms. Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 49th percentile by exploit likelihood (below the median); 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.

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

CVE-2025-70073 is a code injection vulnerability (CWE-94) in ChestnutCMS versions 1.5.8 and earlier. The flaw exists in the template creation function, enabling a remote attacker to execute arbitrary code. Published on 2026-02-05, it carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its network accessibility and potential for significant impact.

Exploitation requires high privileges, such as administrative access, allowing a remote attacker to target the system with low complexity and no user interaction. Upon success, the attacker can execute arbitrary code, achieving high confidentiality, integrity, and availability impacts, potentially leading to full server compromise.

Mitigation details are available in the referenced GitHub issue at https://github.com/liweiyi/ChestnutCMS/issues/8.

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.
