Deeper analysis

GDidees CMS versions 3.9.1 and earlier contain an arbitrary file download vulnerability in the filename parameter of the /_admin/imgdownload.php endpoint. The flaw is tracked as CVE-2023-27179 with a CVSS 3.1 base score of 7.5 and is associated with CWE-434, allowing unauthenticated remote actors to retrieve files from the server filesystem.

An attacker can supply crafted filename values to the affected script and obtain the contents of arbitrary files, resulting in disclosure of sensitive configuration data, source code, or other restricted information without requiring authentication or user interaction.

Public references include proof-of-concept exploits published on Packet Storm and a technical gist demonstrating the traversal technique, along with general guidance on unrestricted file download weaknesses; no vendor advisory or patch information is referenced in the available sources. The EPSS score has remained at its recorded peak of 0.8690 since disclosure, indicating sustained exploitation interest.
