Vulnerability details
The vulnerability allows a low-privileged attacker to disclose server files readable by WeGIA's PHP worker.
The vulnerability exists due to request parameters overwriting upload metadata in web/html/atendido/docfamiliar_upload.php, causing an attacker-supplied path to be read without verifying that it represents an uploaded file. A low-privileged attacker can submit a crafted POST request and retrieve the stored contents through the document viewer when granted resource 11 access, provided database settings permit the document insertion with explicit_defaults_for_timestamp disabled.
