Lifecycle Timeline
7DescriptionCVE.org
A vulnerability was detected in code-projects BloodBank Managing System 1.0. The impacted element is an unknown function of the file request_blood.php. The manipulation results in unrestricted upload. The attack can be executed remotely. The exploit is now public and may be used.
AnalysisAI
Unrestricted file upload in code-projects BloodBank Managing System 1.0 via request_blood.php allows authenticated remote attackers to upload arbitrary files with limited impact. The vulnerability requires valid user credentials (PR:L per CVSS vector) but has low confidentiality, integrity, and availability impact (VC:L/VI:L/VA:L). Publicly available exploit code exists; however, the low CVSS score (2.1) and confined impact scope suggest this poses minimal risk despite public disclosure.
Technical ContextAI
The vulnerability exists in request_blood.php, a PHP application component responsible for blood request processing. CWE-434 (Unrestricted Upload of File with Dangerous Type) indicates insufficient validation or restriction of uploaded files. The application fails to enforce proper file type, extension, or content controls during upload operations. While the description mentions file upload capability, the low impact metrics (VC:L/VI:L/VA:L) suggest either file upload restrictions elsewhere in the application, limited access to uploaded content, or sandboxing of uploaded files that prevents direct code execution or system compromise.
RemediationAI
Apply vendor-released patch or upgrade to a patched version if available from code-projects.org. If no patched version is available, implement immediate compensating controls: (1) Disable the upload feature in request_blood.php or restrict it to administrators only, reducing attack surface from all authenticated users to admin tier. (2) Implement strict server-side file upload validation: whitelist allowed file extensions (e.g., .pdf, .txt only), enforce file type verification via MIME type and magic bytes, and store uploads outside the web root or in a non-executable directory. (3) Apply principle of least privilege - configure the web server process (Apache/Nginx worker) to run with minimal permissions, preventing execution of uploaded files even if bypassed. (4) Regularly audit uploaded file storage for suspicious files. (5) For internet-facing deployments, restrict authenticated access to request_blood.php by network ACL or reverse proxy rules until patched.
