Description

When Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) is configured to use a password file for authentication, any malformed data in the password file will be treated as valid. This typically means that the malformed data becomes a username and no password. If this occurs, clients can circumvent authentication and get access to the broker by using the malformed username. In particular, a blank line will be treated as a valid empty username. Other security measures are unaffected. Users who have only used the mosquitto_passwd utility to create and modify their password files are unaffected by this vulnerability.

Solution(s)

  • suse-upgrade-libmosquitto1
  • suse-upgrade-libmosquittopp1
  • suse-upgrade-mosquitto
  • suse-upgrade-mosquitto-clients
  • suse-upgrade-mosquitto-devel
