Deeper analysis
Microsoft SharePoint Server is affected by CVE-2024-30044, a remote code execution vulnerability published on 14 May 2024 and assigned CWE-502 for unsafe deserialization of untrusted data. The flaw carries a CVSS 3.1 base score of 7.2 with network attack vector, low complexity, and high-privilege requirements, enabling an authenticated attacker to achieve full confidentiality, integrity, and availability impact on the server.
An attacker with SharePoint administrative privileges can send a crafted serialized payload over the network to trigger arbitrary code execution without user interaction. Successful exploitation grants the attacker the ability to run code in the context of the SharePoint application pool, potentially leading to complete server compromise, data exfiltration, or persistence within the SharePoint farm.
Microsoft’s Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-30044 recommends applying the official security update for the affected SharePoint Server versions. The EPSS score rose from a low baseline to a peak of 0.5067 on 18 December 2025 before receding to the current value of 0.1686, indicating a period of increased exploitation interest after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
