Summary

CVE-2024-32987 is a high-severity SSRF (CWE-918) vulnerability in Microsoft Sharepoint Server. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 18% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) 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.

Microsoft SharePoint Server contains an information disclosure vulnerability tracked as CVE-2024-32987. The flaw carries a CVSS 3.1 base score of 7.5 with an attack vector of network, low complexity, and no required privileges or user interaction, resulting in high impact to confidentiality. It is associated with CWE-918, indicating server-side request forgery behavior.

An unauthenticated attacker reachable over the network can send crafted requests that cause the SharePoint server to retrieve and expose internal or otherwise inaccessible resources. Successful exploitation yields disclosure of sensitive information without the need for credentials or user assistance.

The EPSS score started low after the July 2024 disclosure, rose to a peak of 0.0654 on 2025-12-18, and has since receded to 0.0374; this upward trajectory indicates that exploitation interest increased after public release. Practitioners should consult the Microsoft Security Response Center advisory at the listed reference URL for official patch and mitigation guidance.

Mitigating Controls (NIST 800-53 r5) AI

Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.
