CVE-2024-53913
Published: 24 November 2024
Summary
CVE-2024-53913 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-2024-53913 is a deserialization vulnerability affecting the server component of Veritas Enterprise Vault versions prior to 15.2. The flaw, tracked as ZDI-CAN-24343 and assigned CWE-502, arises when untrusted data received over a .NET Remoting TCP port is deserialized without sufficient validation, enabling remote code execution. The issue carries a CVSS 3.1 base score of 9.8.
Unauthenticated remote attackers can send crafted serialized payloads to the affected TCP port and achieve arbitrary code execution on the server with no user interaction required. Successful exploitation grants full control over the Enterprise Vault server, including the ability to read, modify, or delete data and potentially pivot within the environment.
The vendor advisory VTS24-014 published by Veritas at https://www.veritas.com/content/support/en_US/security/VTS24-014 provides official guidance on mitigation, including the availability of version 15.2 that resolves the issue. The associated EPSS score has remained low, reaching a peak of only 0.0556 well after disclosure before receding.

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.
