The vulnerability identified as CVE-2025-26373 is a CWE-862 "Missing Authorization" issue present in Q-Free MaxTime versions up to and including 2.11.0. This vulnerability allows an authenticated low-privileged attacker to enumerate users through crafted HTTP requests.
This vulnerability has a CVSS score of 6.5, categorizing it as medium severity. Organizations should take this vulnerability seriously as it could allow attackers to gain insights into user accounts, potentially leading to further security breaches.
Risk to organizations includes unauthorized user enumeration, which could expose sensitive information or pave the way for more severe attacks. Given its exploitation status, organizations are advised to prioritize patching and remediation efforts.
Organizations should monitor their systems for any signs of exploitation and assess their existing security controls to manage the risks associated with this vulnerability.
Vulnerability Details
The official description for this vulnerability states that it allows an authenticated low-privileged attacker to enumerate users via crafted HTTP requests. The affected component is the maxprofile/users/routes.lua user endpoint within Q-Free MaxTime version 2.11.0 and earlier.
The CVSS score of 6.5 indicates a medium severity level, where the attack vector is classified as network, and the attack complexity is low. This means that an attacker can exploit this vulnerability without needing physical access to the affected system.
Additionally, the confidentiality impact is high, while integrity and availability impacts are none. Therefore, organizations should be aware of the potential for sensitive user data exposure.
Technical Analysis
The root cause of this vulnerability lies in the lack of proper authorization checks in the user enumeration endpoint. Attackers may leverage this flaw to send crafted HTTP requests that exploit this oversight.
The attack vector is network-based, requiring only the ability to send HTTP requests to the vulnerable service. Attack complexity is low, meaning that even individuals with limited technical skills can perform the attack.
The privileges required to exploit this vulnerability are low, as an authenticated user can initiate the attack without needing elevated permissions. User interaction is not required, making it easier for attackers to execute this attack.
The confidentiality impact is high, as successful exploitation could allow attackers to gain access to user information. However, the integrity and availability impacts remain unaffected.
Risk & Impact Analysis
Real-world deployment risk for this vulnerability can be significant, especially for organizations that rely on Q-Free MaxTime for user management. Attackers may exploit this vulnerability to enumerate user accounts, potentially leading to unauthorized access or data leakage.
Organizations should understand that the impact extends beyond just user enumeration; it can also affect customer trust and regulatory compliance. The blast radius potential is concerning, as attackers may pivot from user enumeration to more severe attacks.
Given the CVSS score of 6.5, organizations should address this vulnerability in their priority patch cycle. Organizations should also consider implementing additional security measures, such as monitoring and alerting for unusual user activity.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions prior to vendor patch, specifically Q-Free MaxTime versions less than or equal to 2.11.0 are affected by this vulnerability.
Mitigation & Remediation
Organizations should prioritize patching immediately to mitigate this vulnerability. Ensure that all systems running Q-Free MaxTime are updated to the latest version available from the vendor.
In the absence of an immediate patch, organizations should implement access controls to limit user enumeration and monitor for unusual access patterns. Configuration hardening is also recommended to enhance security.
For further details on security testing, organizations can utilize penetration testing services to validate their security posture.
Detection Guidance
Organizations should monitor logs for unusual patterns of user enumeration requests. Look for repeated access attempts on the user endpoint that may indicate exploitation attempts.
Behavioral anomalies in user activity should also be flagged, as they could indicate an ongoing exploitation. Network signatures associated with unauthorized access attempts should be defined and monitored.
