CVE-2018-20105

CA private-key passphrase disclosure via command logging

Published Jan 27, 2020 · Updated Sep 16, 2024

Sensitive-data logging in yast2-rmt before 1.2.2 allows local users to read the CA private-key passphrase on SLES 15 and openSUSE Leap. The YaST RMT module passes the SSL password to the Cheetah command-line interface in a form that command logging records in a log file. Exploitation requires local access to that log; the exposed passphrase can unlock the RMT custom CA private key, while no data modification or service interruption is reported.
