Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Microsoft SharePoint Server is affected by CVE-2024-38024, a remote code execution vulnerability published on 2024-07-09 and assigned CWE-502. The flaw carries a CVSS 3.1 base score of 7.2 with the vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, indicating that successful exploitation can fully compromise confidentiality, integrity, and availability of the server.
An attacker with high privileges and network access can exploit the issue without user interaction to execute arbitrary code on the SharePoint Server. The attack requires authenticated access but otherwise low complexity, allowing a privileged user to achieve full control over the affected system.
Microsoft’s Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-38024 provides official guidance on available patches and mitigation steps for supported SharePoint Server versions.
The associated EPSS score reached a peak of 0.2166 after disclosure before settling at a current value of 0.1003, indicating a material rise in predicted exploitation likelihood that warrants renewed attention from defenders.

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cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
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.
