Vulnerability Description

 

This advisory covers a problem with a data migration discovered in the OTRS framework.

 

Privilege Escalation

 

 Users updating to OTRS 6.0.13 (also patchlevel updates) or 5.0.31 (only major updates) will experience data loss in their agent preferences table.

 

Affected by this problem are OTRS 6.0.13 and OTRS 5.0.31 (earlier versions are not affected).

This vulnerability is fixed in the latest versions of OTRS, and it is recommended to upgrade to the latest patch level.

As a workaround after a performed migration, users can restore the user_preferences table from their backup and delete the OTRS cache via otrs/bin/otrs.Console.pl Maint::Delete::Cache. If the LDAP Sync module is used, it is sufficient to log in to the system again.
