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-2024-30043 and assigned CWE-611. The flaw received a CVSS 3.1 score of 6.5 with an attack vector of network, low attack complexity, low required privileges, and no user interaction, resulting in high impact to confidentiality while leaving integrity and availability unaffected.
An authenticated attacker with low privileges can send specially crafted requests over the network to the affected SharePoint Server instance and obtain sensitive information that would otherwise be restricted. The same access level is sufficient to trigger the flaw without any additional user interaction or elevated rights on the target system.
Microsoft has published an advisory for CVE-2024-30043 at the Microsoft Security Response Center, which security teams should consult for official patch availability and recommended actions. The current and peak EPSS score for the vulnerability stands at 0.5933.

Mitigating Controls (NIST 800-53 r5) AI
Secure configuration settings can disable external entity processing in XML parsers.
Developer testing can discover XXE flaws through targeted XML parsing tests.
Input validation can reject or sanitize XML containing external entity references.
Mitigating Controls (NIST CSF 2.0) AI
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.
Hardened XML parser configurations directly disable external entity resolution.
Secure SDLC practices include input validation and safe XML parser configuration that prevent XXE.
Vulnerability scanning can discover XXE flaws but does not prevent their introduction in code.
Patching eliminates XXE-vulnerable parser versions but is only one aspect of software maintenance.

Security testing in development catches XXE via static analysis and dynamic XML fuzzing.
Vulnerability management identifies and patches XML libraries with unsafe default entity settings.
Secure development life cycle mandates input validation and entity handling that directly prevents XXE.
Application security requirements explicitly call for disabling external entity processing in XML parsers.
Secure architecture principles include safe parser configuration that mitigates external entity risks.
Secure coding standards require disabling DTDs and external entities in XML processing.
