CVE-2025-13044: CWE-340 Generation of Predictable Numbers or Identifiers in IBM Concert
IBM Concert versions 1. 0. 0 through 2. 2. 0 have a vulnerability where temporary files are created with predictable names. This flaw allows local users to perform a symlink attack to overwrite arbitrary files. The vulnerability does not affect confidentiality or availability but impacts integrity. It has a CVSS score of 6. 2, indicating medium severity. No official patch or remediation guidance is currently available from the vendor.
AI Analysis
Technical Summary
CVE-2025-13044 is a vulnerability in IBM Concert (versions 1.0.0 through 2.2.0) where temporary files are created using predictable filenames. This weakness (CWE-340) enables local attackers to create symbolic links pointing to arbitrary files, which can then be overwritten when the application writes to these temporary files. The vulnerability requires local access and low attack complexity, with no privileges or user interaction needed. The impact is limited to integrity, as attackers can overwrite files but cannot affect confidentiality or availability. The CVSS 3.1 base score is 6.2 (AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N).
Potential Impact
The vulnerability allows local attackers to overwrite arbitrary files by exploiting predictable temporary file names via symlink attacks. This compromises the integrity of affected systems but does not impact confidentiality or availability. There are no known exploits in the wild, and the attack requires local access.
Mitigation Recommendations
No official patch or remediation level has been provided by IBM as of the current information. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict local user permissions to prevent unauthorized file creation and symlink manipulation in directories used by IBM Concert for temporary files.
