Local Root Exploit via Configuration Dictionary in dnf5daemon-serverΒ before 5.1.17 allows a malicious user to impact Confidentiality and Integrity via Configuration Dictionary.

There are issues with the D-Bus interface long before Polkit is invoked. The org.rpm.dnf.v0.SessionManager.open_session method takes a key/value map of configuration entries. A sub-entry in this map, placed under the β€œconfig” key, is another key/value map. The configuration values found in it will be forwarded as configuration overrides to the libdnf5::Base configuration.

Practically all libdnf5 configuration aspects can be influenced here. Already when opening the session via D-Bus, the libdnf5 will be initialized using these override configuration values. There is no sanity checking of the content of this β€œconfig” map, which is untrusted data.Β It is possible to make the library loading a plug-in shared library under control of an unprivileged user, hence achieving root access.
