Overview
A critical vulnerability, identified as CVE-2025-63748, has been discovered in QaTraq version 6.9.2. This vulnerability allows authenticated users to upload arbitrary files, including executable PHP files, through the “Add Attachment” feature within the “Test Script” module. Successful exploitation of this vulnerability can lead to remote code execution (RCE) on the server.
Technical Details
The vulnerability stems from the lack of proper file type validation in the “Add Attachment” functionality. QaTraq 6.9.2 does not adequately restrict the types of files that can be uploaded. An authenticated user can upload a malicious PHP file through the “Test Script” module. Upon uploading, the application stores the file on the server.
The “View Attachment” option then provides a direct path to access and execute the uploaded file. By navigating to this path, the malicious PHP code will be executed by the server, potentially allowing the attacker to gain control of the system, access sensitive data, or perform other malicious actions.
CVSS Analysis
Unfortunately, a CVSS score and severity level are not currently available for CVE-2025-63748. However, given the ability to achieve remote code execution, this vulnerability should be considered a high risk.
Possible Impact
The exploitation of CVE-2025-63748 can have severe consequences, including:
- Remote Code Execution (RCE): Attackers can execute arbitrary code on the server, potentially leading to complete system compromise.
- Data Breach: Unauthorized access to sensitive data stored on the server.
- System Takeover: Attackers can gain full control of the affected server, leading to denial of service or further attacks on other systems.
- Malware Distribution: The compromised server can be used to distribute malware to other users or systems.
Mitigation and Patch Steps
To mitigate the risk posed by CVE-2025-63748, the following steps are recommended:
- Apply the Patch: Upgrade QaTraq to a version that addresses this vulnerability. Contact the vendor for patch availability.
- Implement File Type Validation: Restrict file uploads to only allow specific, safe file types (e.g., .txt, .pdf). Use a whitelist approach instead of a blacklist.
- Sanitize File Names: Sanitize uploaded file names to remove potentially dangerous characters or extensions.
- Secure File Storage: Store uploaded files outside of the webroot or in a directory with restricted access.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities.
- Web Application Firewall (WAF): Implement a Web Application Firewall (WAF) to detect and block malicious requests.
