Risk to organizations includes unauthorized access to sensitive data and the potential for further attacks leveraging compromised systems. Given the nature of the vulnerability, organizations should prioritize patching immediately.
Currently, there are no known exploits or public proof-of-concept (PoC) code available for this vulnerability. However, the lack of available exploits does not mitigate the urgency for remediation.
Organizations using Q-Free MaxTime should assess their exposure to this vulnerability and take necessary actions to apply available patches or implement workarounds.
Vulnerability Details
The vulnerability described in CVE-2025-26356 is a CWE-35 "Path Traversal" issue that affects the setActive endpoint within the Q-Free MaxTime application. The vulnerability allows authenticated attackers to overwrite sensitive files by sending specially crafted HTTP requests. The affected versions are all releases of MaxTime up to and including version 2.11.0.
The CVSS 3.1 score of 7.2 indicates a high severity level, with an attack vector categorized as NETWORK. The attack complexity is low, meaning that an attacker could exploit the vulnerability with relative ease, provided they have authenticated access. The consequences of a successful attack could lead to high impacts on confidentiality, integrity, and availability.
The vulnerability was published on February 12, 2025. Organizations should act quickly to mitigate this risk.
Technical Analysis
The root cause of the vulnerability stems from improper validation of user-supplied input. Attackers may leverage this vulnerability by crafting malicious HTTP requests that manipulate file paths, allowing them to access restricted directories and overwrite sensitive files.
The vulnerability can be exploited through a network attack, requiring high privileges to be achieved. Importantly, no user interaction is required for an attack to succeed. The impacts on confidentiality, integrity, and availability are significant, which means organizations must treat this vulnerability with utmost seriousness.
Risk & Impact Analysis
Real-world deployment of Q-Free MaxTime in sensitive environments poses critical risks. Attackers exploiting this vulnerability could potentially gain unauthorized access to sensitive files, leading to data breaches and other forms of compromise.
The urgency for organizations to address this vulnerability is underscored by its high CVSS score and the potential for significant damage. The blast radius could extend to any system utilizing affected versions of MaxTime, with the potential for cascading failures across interconnected systems.
Organizations should assess their deployment and prioritize patching efforts to mitigate risks associated with this vulnerability.
