Description

An unsafe parsing of OpenMQ's configuration in OpenMQ versions <6.5.2 and <6.9.0, allows a remote attacker to read arbitrary files from a MQ Broker's server. A full exploitation could read unauthorized files of the OpenMQ’s host OS. In some scenarios RCE could be achieved. This is fixed in OpenMQ 6.5.2, 6.9.0, and in GlassFish 7.0.26, 7.1.1, and 8.0.2.

• CWE-27Path Traversal: 'dir/../../filename'The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize multiple internal "../" sequences that can resolve to a location that is outside of that directory.
