Overview
CVE-2025-13544 describes a medium severity unrestricted file upload vulnerability affecting the ashraf-kabir travel-agency software. This vulnerability, discovered in the /customer_register.php file, allows remote attackers to upload arbitrary files, potentially leading to code execution or other malicious activities on the server.
Technical Details
The vulnerability resides within an unknown function of the /customer_register.php file. By manipulating input during the customer registration process, an attacker can bypass file type restrictions and upload malicious files to the server. The specific commit affected is up to 1f25aa03544bc5fb7a9e846f8a7879cecdb0cad3. The vendor utilizes rolling releases, making specific version identification difficult. The vulnerability has been publicly disclosed, increasing the risk of exploitation.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns CVE-2025-13544 a score of 6.3, indicating a MEDIUM severity. This score reflects the potential impact of the vulnerability and the relative ease with which it can be exploited.
- Base Score: 6.3
- Vector: The CVSS vector would need to be reconstructed to get the finer detail on the precise weighting; since it wasn’t provided we cannot fully reconstruct. It would include elements of network attack vector, low complexity, requires no privileges, requires no user interaction, and would rate confidentiality, integrity and availability impact in some way.
Possible Impact
Successful exploitation of this vulnerability can have severe consequences, including:
- Remote Code Execution (RCE): Uploaded files could contain malicious code that, when executed, allows the attacker to gain control of the server.
- Website Defacement: Attackers could upload files to deface the website, damaging the organization’s reputation.
- Data Theft: An attacker could gain access to sensitive data stored on the server, such as customer information or financial records.
- Malware Distribution: The compromised server could be used to host and distribute malware to visitors.
Mitigation or Patch Steps
Unfortunately, the vendor has not responded to disclosure attempts and no specific patch or updated version is available. Therefore, immediate mitigation steps are crucial:
- Input Validation: Implement strict input validation on the
/customer_register.phpfile to ensure that only allowed file types are accepted. Specifically, check the file extension, MIME type, and file content. - File Size Limits: Enforce file size limits to prevent attackers from uploading excessively large files.
- Secure File Storage: Store uploaded files in a non-executable directory and rename them to prevent direct access.
- Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block malicious file upload attempts. Configure the WAF to inspect file uploads for suspicious content.
- Regular Security Audits: Conduct regular security audits to identify and address potential vulnerabilities in the application.
- Monitor Website Activity: Continuously monitor website activity for suspicious behavior, such as unusual file uploads or attempts to access restricted areas.
