CVE-2025-26349 is classified as a high-severity vulnerability affecting Q-Free MaxTime software versions less than or equal to 2.11.0. This vulnerability allows authenticated remote attackers to exploit a relative path traversal issue within the file upload mechanism. The potential risk of this vulnerability is significant, as it could enable attackers to overwrite arbitrary files on the server through crafted HTTP requests.
With a CVSS score of 7.2, this vulnerability falls into the high-severity category due to its potential for serious impact on confidentiality, integrity, and availability. Organizations utilizing affected versions of Q-Free MaxTime are at risk of unauthorized access and modifications to critical files, underscoring the urgency for remediation.
Currently, there is no public exploit confirmed for this vulnerability, and it is not included in the Known Exploited Vulnerabilities (KEV) catalog. However, the threat remains as attackers may leverage this vulnerability in tailored attacks against organizations using the affected software.
Organizations should prioritize patching immediately, as the risks associated with this vulnerability could lead to significant operational and reputational damage.
Vulnerability Details
The vulnerability identified as CVE-2025-26349 relates to a CWE-23 "Relative Path Traversal" within the file upload functionality of Q-Free MaxTime. It was published on February 12, 2025, and allows authenticated attackers to overwrite arbitrary files by sending specially crafted HTTP requests. The affected versions are all releases of Q-Free MaxTime up to and including version 2.11.0.
The CVSS score of 7.2 indicates a high level of severity, with the following metrics: attack vector is network-based, the attack complexity is low, and the privileges required for exploitation are high. The confidentiality, integrity, and availability impacts are all rated as high, representing a significant risk for the systems involved.
Technical Analysis
The root cause of CVE-2025-26349 is a failure to correctly sanitize user input in the file upload mechanism. This oversight allows attackers to manipulate file paths, potentially leading to unauthorized access and modification of files on the server.
The attack vector for this vulnerability is network-based, meaning it can be exploited remotely over the internet. The complexity of the attack is considered low, as it does not require any special conditions or extensive knowledge to execute successfully. However, it does require high privileges, indicating that the attacker must be an authenticated user.
User interaction is not required for the exploitation of this vulnerability, which further increases the risk, as attackers can automate the process. The impacts on confidentiality, integrity, and availability are all rated high, indicating that an exploitation could lead to significant data breaches or service disruptions.
Risk & Impact Analysis
The deployment risk associated with CVE-2025-26349 is substantial, particularly for organizations that rely on Q-Free MaxTime for operational processes. The ability for authenticated users to exploit this vulnerability raises concerns about insider threats and the potential for malicious actors to gain unauthorized access to sensitive data.
This vulnerability emphasizes the importance of proper input validation and file handling practices. Organizations must understand that the blast radius of this issue could extend beyond individual systems, potentially impacting entire networks and leading to widespread data compromise.
Given the CVSS score of 7.2 and the absence of any confirmed public exploits, organizations should still assess their exposure and prioritize remediation. The low EPSS score of 0.0047 indicates that while the immediate threat may not be high, it is crucial to address vulnerabilities in a timely manner to avoid potential future exploitation.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects all versions of Q-Free MaxTime up to and including version 2.11.0. Organizations using any version within this range should take immediate action to mitigate risks.
Mitigation & Remediation
Organizations should ensure that they upgrade to the latest version of Q-Free MaxTime to mitigate this vulnerability. If an immediate upgrade is not feasible, consider implementing the following workarounds:
1. Validate and sanitize all user inputs, especially in file upload mechanisms.
2. Restrict file upload permissions to minimize the risk of unauthorized file overwrites.
3. Monitor logs for any unusual file access patterns that may indicate attempted exploitation.
For more detailed guidance on securing applications, organizations can refer to resources related to application security assessments.
Detection Guidance
To detect potential exploitation attempts against this vulnerability, organizations should monitor for the following indicators:
1. Log entries indicating file uploads with unexpected paths or filenames.
2. Unauthorized access attempts to sensitive files that should not be accessible to authenticated users.
3. Behavioral anomalies in user access patterns, particularly from accounts with elevated privileges.
