Summary

Arbitrary file upload vulnerability due to a lack of proper validation in upload forms. This allows authenticated users to upload files to the server without restrictions. An attacker could exploit this flaw to execute malicious code remotely (demonstrated by uploading the EICAR test file), which could result in the system being completely compromised.

Risk Assessment

An authenticated attacker can upload and execute malicious code on the server, leading to complete system compromise.

Recommendation

Implement strict validation of uploaded file types and extensions and restrict the upload directory. Update the software containing the vulnerable upload form.
