Overview
CVE-2025-13238 describes a medium-severity vulnerability found in Bdtask Flight Booking Software version 4. This security flaw allows for unrestricted file uploads, potentially enabling attackers to execute arbitrary code on the server. The vendor has been notified but has not yet responded to address this vulnerability.
Technical Details
The vulnerability resides within the /agent/profile/edit endpoint, specifically on the Edit Profile Page. An attacker can manipulate the file upload process to bypass security checks and upload malicious files, such as PHP scripts or other executable content. This unrestricted upload capability can be exploited remotely.
The vulnerability allows an attacker to upload arbitrary files to the server without proper validation. Publicly available proof-of-concept (PoC) exploit code demonstrates the ease with which this vulnerability can be exploited.
CVSS Analysis
The vulnerability has a CVSS score of 6.3 (MEDIUM). This score reflects the remote exploitability of the vulnerability and the potential impact on the system. The CVSS vector indicates a relatively straightforward attack requiring minimal user interaction.
Possible Impact
Exploitation of this vulnerability could have severe consequences, including:
- Remote Code Execution (RCE): Attackers could execute arbitrary code on the server, potentially leading to complete system compromise.
- Data Breach: Uploaded malicious scripts could steal sensitive data from the database or other parts of the system.
- Website Defacement: Attackers could replace the website’s content with malicious or unwanted content.
- Denial of Service (DoS): Malicious files could consume server resources, leading to a denial of service for legitimate users.
Mitigation or Patch Steps
Since the vendor has not released a patch, the following mitigation steps are recommended:
- Implement Strict File Type Validation: Ensure that only allowed file types are accepted, based on both file extension and content type (MIME type) verification.
- Sanitize File Names: Remove any potentially malicious characters from uploaded file names.
- Store Uploaded Files Outside the Web Root: Store uploaded files in a directory that is not directly accessible from the web, preventing direct execution.
- Implement Access Controls: Restrict access to the
/agent/profile/editendpoint and any associated file upload functionality. - Web Application Firewall (WAF): Utilize a WAF to detect and block malicious requests targeting the file upload vulnerability.
- Monitor System Logs: Monitor server logs for suspicious activity related to file uploads.
