CVE-2025-26344 is a critical vulnerability classified under CWE-306, indicating a "Missing Authentication for Critical Function" in Q-Free MaxTime's guest mode functionality. This vulnerability allows an unauthenticated remote attacker to enable passwordless guest mode through specially crafted HTTP requests. As a result, unauthorized access may be granted, leading to potential abuse of the service.
With a CVSS score of 9.8, the severity of this vulnerability is classified as critical, underscoring the importance of immediate remediation. Organizations utilizing Q-Free MaxTime versions less than or equal to 2.11.0 are at risk, and mitigation steps should be prioritized to prevent unauthorized access.
Risk to organizations includes potential unauthorized access to critical functions without authentication, which could compromise sensitive data or system integrity. Currently, there are no known public exploits for this vulnerability, but the potential for exploitation is significant given its nature.
Organizations should prioritize patching immediately to secure their systems against this vulnerability and evaluate their existing security measures to ensure they are robust against similar threats.
Vulnerability Details
The vulnerability in Q-Free MaxTime allows attackers to bypass authentication mechanisms for critical functions, specifically in the maxprofile/guest-mode/routes.lua component. The affected versions include all versions prior to 2.11.0, and the vulnerability was published on February 12, 2025.
The CVSS 3.1 vector string for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating a network attack vector with low complexity and no required privileges or user interaction. The potential impacts on confidentiality, integrity, and availability are all classified as high.
Technical Analysis
The root cause of this vulnerability stems from a lack of authentication checks within the guest mode functionality. Attackers may leverage this flaw by sending specially crafted HTTP requests that exploit the absence of security controls. The attack vector is network-based, and the complexity of executing this attack is considered low, as no authentication is required.
Given that the attacker does not require any privileges or user interaction, this vulnerability poses a significant threat. The potential impacts on confidentiality, integrity, and availability are all high, as unauthorized access to guest mode may lead to further exploitation within the system.
Risk & Impact Analysis
Real-world deployment of Q-Free MaxTime with this vulnerability could lead to unauthorized access to critical functionalities. The absence of password protection in guest mode increases the risk of data breaches and service disruptions. Organizations must understand the potential blast radius of this vulnerability, as it could be exploited to access sensitive information or disrupt service availability.
The urgency for organizations to address this vulnerability is critical, given its high CVSS score and the potential for exploitation. Immediate action is required to patch vulnerable systems and to review access controls to ensure that similar vulnerabilities are not present in other areas.
