AI Analysis

Impact

A flaw in the move_uploaded_file function of TinyFileManager versions up to 2.6 allows an attacker to manipulate the fullpath parameter, enabling unrestricted file upload. This weakness permits the delivery of malicious files, including executable scripts, which can result in remote code execution and total compromise of the web server. The vulnerability reflects weaknesses in access control (CWE-284) and file-type validation (CWE-434).

Affected Systems

The vulnerability affects TinyFileManager released by prasathmani, specifically all versions up to and including 2.6. Users running these versions on any server that exposes the application to the internet are exposed.

Risk and Exploitability

The CVSS score is 5.3, indicating moderate severity, and the EPSS score is not available. The vulnerability is not listed in the CISA KEV catalog, yet an exploit has already been released to the public. The attack vector is remote, via the web interface, and the flaw can be abused without authentication if the upload endpoint is publicly accessible. Consequently, the likelihood of exploitation remains significant for exposed installations.

OpenCVE Recommended Actions

  • Disable the file upload feature or limit it to privileged users only.
