CVE-2024-7506 Overview
CVE-2024-7506 is an unrestricted file upload vulnerability in itsourcecode Tailoring Management System 1.0. The flaw resides in the /setlogo.php script, where the bgimg parameter accepts arbitrary file uploads without proper validation. An authenticated remote attacker can abuse this weakness to place attacker-controlled files on the server, potentially leading to code execution within the web application context. The vulnerability is classified under CWE-434: Unrestricted Upload of File with Dangerous Type. Public disclosure of exploitation details has been made through VulDB entry VDB-273649.
Critical Impact
Remote attackers with low-level privileges can upload arbitrary files through the bgimg parameter of /setlogo.php, enabling potential webshell deployment and server compromise.

Technical Details for CVE-2024-7506
Vulnerability Analysis
The vulnerability exists in the logo configuration functionality of the Tailoring Management System. The /setlogo.php endpoint processes user-supplied file uploads via the bgimg argument without enforcing file type, extension, or MIME validation. This missing sanitization allows an attacker to submit executable server-side scripts such as PHP files instead of legitimate image content. Once uploaded, the malicious file can be requested through the web server and executed within the application context. Successful exploitation supports remote command execution, data theft, and lateral movement within the hosting environment.
Root Cause
The root cause is a failure to validate uploaded file content and extension in the bgimg handler of /setlogo.php. The application accepts any file supplied to the parameter and stores it in a web-accessible directory. No allow-listing of image MIME types, no magic-byte inspection, and no server-side extension filtering are enforced. This maps directly to CWE-434: Unrestricted Upload of File with Dangerous Type.
Attack Vector
The attack is launched over the network against the vulnerable PHP endpoint. An attacker authenticates to the application with any valid low-privilege account and submits a crafted multipart POST request to /setlogo.php targeting the bgimg field. The payload is a server-executable script disguised as or in place of an image asset. After upload, the attacker requests the stored file directly to trigger execution. Public exploitation details are referenced in the GitHub CVE Issue Discussion and VulDB Exploit Reference #273649.

Detection Methods for CVE-2024-7506
Indicators of Compromise
- Unexpected files with executable extensions (.php, .phtml, .phar) present in directories used by setlogo.php for image storage.
- HTTP POST requests to /setlogo.php containing the bgimg parameter with non-image Content-Type values or filenames.
- Outbound connections originating from the PHP web server process to unfamiliar hosts following a setlogo.php request.
Detection Strategies
- Inspect web server access logs for POST requests to /setlogo.php and correlate with subsequent GET requests to newly created files in the upload path.
- Deploy web application firewall (WAF) rules that inspect multipart uploads and reject requests where the bgimg field carries non-image MIME types or double extensions.
- Monitor filesystem integrity in the application's upload directory for creation of files with server-executable extensions.
Monitoring Recommendations
- Enable process monitoring on the web server host to flag child processes spawned by the PHP interpreter, such as sh, bash, cmd.exe, or powershell.exe.
- Alert on file creation events in web-accessible directories where the file magic bytes do not match the declared image extension.
- Retain full request bodies for /setlogo.php transactions for forensic review.
How to Mitigate CVE-2024-7506
Immediate Actions Required
- Restrict network access to the Tailoring Management System to trusted users while a fix is unavailable.
- Disable or remove the /setlogo.php endpoint if the logo upload feature is not operationally required.
- Audit the upload directory for unauthorized files and remove any suspicious scripts.
- Rotate credentials for all application accounts, as low-privilege access is required for exploitation.
Patch Information
No vendor advisory or official patch has been published for itsourcecode Tailoring Management System 1.0 at the time of this writing. Organizations relying on this application should treat it as unpatched and apply compensating controls. Track updates through VulDB CTI Information #273649.
Workarounds
- Configure the web server to deny script execution in the upload directory using directives such as php_admin_flag engine off in Apache or an equivalent location block in Nginx.
- Add a reverse-proxy or WAF rule that rejects uploads to /setlogo.php where the request body's magic bytes do not match a known image format (JPEG, PNG, GIF).
- Enforce filename rewriting on upload so stored files carry a fixed non-executable extension (for example, .img).
- Apply strict allow-listing of MIME types and validate uploaded content using server-side magic-byte checks before persistence.
