CVE-2024-53909
Published: 24 November 2024
Summary
CVE-2024-53909 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Veritas Enterprise Vault. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 11.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2024-53909 is a deserialization vulnerability (CWE-502) in the server component of Veritas Enterprise Vault versions prior to 15.2. The flaw stems from the handling of untrusted data arriving on a .NET Remoting TCP port, which is deserialized without sufficient validation and enables remote code execution.
An unauthenticated attacker with network access can send crafted serialized payloads to the affected TCP port and achieve arbitrary code execution on the server, resulting in full compromise of confidentiality, integrity, and availability as reflected in the CVSS 9.8 base score.
The vendor advisory VTS24-014 addresses the issue and directs customers to upgrade to Enterprise Vault 15.2 or later to eliminate the unsafe deserialization path.
EPSS scores have remained low, reaching a peak of only 0.0556 before receding, with no indication of widespread exploitation activity.

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.
