Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Microsoft SharePoint contains a remote code execution vulnerability tracked as CVE-2024-38094 and assigned CWE-502 for deserialization of untrusted data. The flaw affects on-premises SharePoint deployments and carries a CVSS 3.1 base score of 7.2, reflecting network attack vector, low complexity, and the requirement for high-privileged credentials.
An authenticated attacker with administrative privileges can send a crafted request that triggers unsafe deserialization, resulting in arbitrary code execution on the SharePoint server. Successful exploitation grants the attacker full control over confidentiality, integrity, and availability of the affected system without user interaction.
Microsoft has published an advisory detailing the affected versions and remediation steps, while CISA has added the CVE to its Known Exploited Vulnerabilities catalog, confirming active exploitation in the wild. The current and peak EPSS score of 0.7032 indicates sustained exploitation interest since disclosure.
Administrators should apply the vendor-supplied updates immediately and review SharePoint server configurations for any exposed administrative interfaces.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can uncover deserialization flaws before deployment.
Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.
Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.
Integrity verification tools can detect malformed or tampered serialized data after the fact.

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.

Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.
Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.
Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.
Mandatory malware scanning of data received over networks or storage media intercepts malicious serialized payloads before they are deserialized by the target application.
