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. If the upload contains a payload that can further exploit the server or its network, the launch of a larger scale attack may be possible.

An ActiveMQ Discovery service was reachable by default from an OpenEdge Management installation when an OEE/OEM auto-discovery feature was activated.  Unauthorized access to the discovery service's UDP port allowed content injection into parts of the OEM web interface making it possible for other types of attack that could spoof or deceive web interface users.   Unauthorized use of the OEE/OEM discovery service was remediated by deactivating the discovery service by default.

An attacker who can produce a malformed web request may cause the crash of a PASOE agent potentially disrupting the thread activities of many web application clients. Multiple of these DoS attacks could lead to the flooding of invalid requests as compared to the server’s remaining ability to process valid requests.
