CVE-2025-13185 Overview
CVE-2025-13185 is an unrestricted file upload vulnerability affecting Bdtask News365 versions up to 7.0.3. The flaw resides in the /admin/dashboard/profile endpoint, where the profile_image and banner_image parameters fail to validate uploaded file content. An authenticated attacker with administrative privileges can manipulate these parameters to upload arbitrary files to the server. The vulnerability is categorized under [CWE-434] (Unrestricted Upload of File with Dangerous Type) and [CWE-284] (Improper Access Control). Public disclosure has occurred, and the vendor was contacted prior to release but did not respond.
Critical Impact
Authenticated attackers can upload arbitrary files through the admin profile endpoint, enabling potential web shell deployment and persistent server-side access.
Affected Products
- Bdtask News365 versions up to and including 7.0.3
- CodeCanyon News365 distribution package
- Deployments using the /admin/dashboard/profile upload handler

Technical Details for CVE-2025-13185
Vulnerability Analysis
The vulnerability stems from missing content-type and extension validation on the administrative profile management endpoint. The /admin/dashboard/profile handler accepts file uploads through the profile_image and banner_image form parameters without enforcing a strict allow-list of permitted file types. An attacker who possesses or obtains administrator credentials can submit a crafted multipart request containing executable server-side code, such as a PHP file disguised as an image. Because the file is written to a web-accessible directory, the attacker can subsequently request the uploaded file to trigger code execution.
The weakness intersects two CWE classes. [CWE-434] describes the unrestricted upload itself, while [CWE-284] reflects the broader access control failure that allows the dangerous file to be reached and executed after upload. Successful exploitation provides a foothold for lateral movement, data theft, or full application compromise.
Root Cause
The root cause is inadequate server-side validation of uploaded file content. The application appears to trust client-supplied MIME types or file extensions rather than verifying the file structure and constraining the storage path. No allow-list of safe extensions, content inspection, or randomized non-executable storage location is enforced.
Attack Vector
Exploitation requires network access to the application and valid high-privilege administrative credentials. The attacker submits a multipart/form-data POST request to /admin/dashboard/profile, substituting a malicious payload in the profile_image or banner_image field. After upload, the attacker requests the resulting file path through the web server to execute the embedded code.
No verified proof-of-concept code is available. Refer to the GitHub Issue #5 Discussion and VulDB #332473 for additional technical details.
Detection Methods for CVE-2025-13185
Indicators of Compromise
- Unexpected files with executable extensions (.php, .phtml, .phar) within the News365 uploads or profile image directories.
- POST requests to /admin/dashboard/profile containing multipart payloads where profile_image or banner_image filenames carry non-image extensions.
- Subsequent GET requests to files inside the upload directory followed by outbound connections from the web server process.
Detection Strategies
- Inspect web server access logs for administrative upload requests and correlate them with later direct requests to the stored file paths.
- Apply web application firewall rules that block multipart uploads where the declared content-type conflicts with the file's magic bytes.
- Hash and inventory all files in News365 upload directories, alerting on the introduction of any non-image file type.
Monitoring Recommendations
- Monitor process creation by the PHP-FPM or web server user for spawning of shells, curl, wget, or other post-exploitation tooling.
- Track authentication events on the News365 admin panel for unusual source IPs or off-hours logins that precede profile updates.
- Alert on file writes to web-root directories outside of expected deployment activity.
How to Mitigate CVE-2025-13185
Immediate Actions Required
- Restrict network access to /admin/dashboard/profile to trusted administrative IP ranges using a reverse proxy or firewall.
- Rotate all administrator credentials and enforce multi-factor authentication on the News365 admin panel.
- Audit upload directories for any files that are not legitimate images and remove unauthorized artifacts.
Patch Information
No vendor advisory or patch has been published. The vendor did not respond to disclosure outreach. Operators should track the VulDB Citation #332473 entry for updates and apply vendor fixes once released.
Workarounds
- Configure the web server to disable script execution within News365 upload directories using directives such as php_admin_flag engine off or equivalent location-based handlers.
- Place a web application firewall rule in front of the application that rejects uploads whose magic bytes do not match the image/jpeg, image/png, or image/gif signatures.
- Implement file integrity monitoring on upload directories to detect and quarantine newly introduced non-image files.
