Description

This issue affects Progress Application Server (PAS) for OpenEdge in versions 11.7 prior to 11.7.18, 12.2 prior to 12.2.13, and innovation releases prior to 12.8.0. An attacker can formulate a request for a WEB transport that allows unintended file uploads to a server directory path on the system running PASOE.
