CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2025-49704 is a high-severity Code Injection (CWE-94) vulnerability in Microsoft Sharepoint Server. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 0.0% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
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-2025-49704 is a code injection vulnerability, tracked under CWE-94, that affects Microsoft Office SharePoint. The flaw permits improper control over code generation and carries a CVSS 3.1 score of 8.8, reflecting network attack vector, low attack complexity, and low privileges required with no user interaction needed.
An authorized attacker with network access can exploit the issue to execute arbitrary code on affected SharePoint servers, resulting in full compromise of confidentiality, integrity, and availability on the target system.
Microsoft’s Security Response Center advisory and accompanying security blog describe available patches for on-premises SharePoint deployments, while CISA lists the CVE in its Known Exploited Vulnerabilities catalog and references coordinated efforts to disrupt active exploitation.
The EPSS score rose from lower values after the July 2025 disclosure to a peak of 0.7661 on 2025-12-11 before receding to the current 0.5958, indicating increased exploitation interest several months post-publication.

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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
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 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

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.
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.
