enterprise_vault: Deserialization of Untrusted Data
CVE-2024-53914 is a critical-severity deserialization of untrusted data vulnerability in enterprise_vault from Veritas, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected enterprise_vault versions: 14.0 through 14.5.1; 15.0 through 15.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.94% chance of exploitation within 30 days, higher than 62% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of enterprise_vault you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on veritas.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Veritas | enterprise_vault | 14.0 through 14.5.1; 15.0 through 15.1 | Not stated |
Version data comes from the organisation that assigned the CVE. Confirm against the vendor advisory before deciding you are unaffected.

Official description
An issue was discovered in the server in Veritas Enterprise Vault before 15.2, ZDI-CAN-24344. It allows remote attackers to execute arbitrary code because untrusted data, received on a .NET Remoting TCP port, is deserialized.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
How developers prevent this class of flaw
- If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
- When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
- Explicitly define a final object() to prevent deserialization.
