CVE-2024-38018 is a critical remote code execution vulnerability in Microsoft SharePoint Server. The provided content indicates the root cause is in SharePoint deserialization logic, specifically SPSerializationBinder.IsAllowedType(), where deserialization was allowed too broadly for types associated with SafeControls. Supporting analysis in the content states Microsoft’s fix restricted deserialization to a narrower allowlist of permitted types. Additional context notes that vulnerable deserialization paths may also involve ExcelDataSet.get_DataTable and DataSetSurrogateSelector-related behavior. Microsoft assessed the issue as network-exploitable and more likely to be exploited, with a CVSS v3 score of 8.8.
