Security Bulletin

This security bulletin contains one critical risk vulnerability.

1) Input validation error

EUVDB-ID: #VU105485

Risk: Critical

CVSSv4.0: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Red]

CVE-ID: CVE-2025-24813

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input when handling file uploads via HTTP PUT requests. A remote attacker can send a specially crafted HTTP PUT request to the server and gain access to sensitive information or even execute arbitrary code.

If all of the following were true, a malicious user was able to view security sensitive files and/or inject content into those files:

  • writes enabled for the default servlet (disabled by default)
  • support for partial PUT (enabled by default)
  • a target URL for security sensitive uploads that is a sub-directory of a target URL for public uploads
  • attacker knowledge of the names of security sensitive files being uploaded
  • the security sensitive files also being uploaded via partial PUT

If all of the following were true, a malicious user was able to perform remote code execution:

  • writes enabled for the default servlet (disabled by default)
  • support for partial PUT (enabled by default)
  • application was using Tomcat's file based session persistence with the default storage location
  • application included a library that may be leveraged in a deserialization attack


Mitigation
