IBM Concert versions 1.0.0 through 2.2.0 create temporary files with predictable names, which allows local users to overwrite arbitrary files via a symlink attack. This vulnerability is classified as medium severity, with a CVSS score of 6.2, signifying a potential threat to organizations utilizing this software.
The risk to organizations includes unauthorized file overwrites, which can compromise the integrity of sensitive data and lead to further exploitation. Given the nature of this vulnerability, organizations should prioritize patching immediately.
As of now, there is no known public exploit or proof of concept available for this vulnerability. However, the low attack complexity and the lack of required privileges make it a concerning issue for organizations.
Organizations using IBM Concert should assess their exposure and apply relevant patches as soon as possible to mitigate the risk associated with this vulnerability.
Vulnerability Details
The official description of CVE-2025-13044 indicates that IBM Concert creates temporary files with predictable names, making it susceptible to a symlink attack. This leads to potential file overwriting, which can have serious impacts on system integrity.
The CVSS score of 6.2 categorizes this vulnerability as medium severity, indicating a moderate risk. The vulnerability affects versions 1.0.0 through 2.2.0 of the IBM Concert software, which has been analyzed and confirmed.
The vulnerability is classified under CWE-340, indicating a potential issue with predictable file handling. Organizations should remain vigilant and consider this vulnerability in their risk assessments.
Technical Analysis
The root cause of this vulnerability lies in the way IBM Concert handles temporary file creation. By generating files with predictable names, it inadvertently opens the door for local users to create symlinks that can point to sensitive files, thereby allowing overwrites.
The attack vector for this vulnerability is local, meaning an attacker would need local access to exploit it. The attack complexity is considered low, as it does not require advanced skills or resources. Additionally, no privileges are needed to exploit this vulnerability, and user interaction is not necessary.
In terms of impact, the confidentiality of data is not affected, but the integrity impact is high due to potential file overwrites. Availability is not impacted, making this a targeted risk for integrity-focused attacks.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-13044 is significant for organizations using IBM Concert. The ability for local users to overwrite arbitrary files can lead to data corruption, unauthorized modifications, and potential system failures.
Organizations should evaluate the potential blast radius of this vulnerability, which can extend to any file that is overwritten, including critical application files. The urgency of addressing this vulnerability is supported by its medium CVSS score and the potential damage it can cause.
Given the findings from the KEV data, this vulnerability does not currently appear to be actively exploited in the wild. However, organizations should still prioritize remediation due to the inherent risks associated with local access vulnerabilities.
