Vulnerability Description

This advisory covers vulnerabilities discovered in the OTRS framework.

Privilege Escalation

In the customer or external frontend, personal information of agents can be disclosed like Name and mail address in external notes.

Affected by this vulnerability are all releases of OTRS 7.0.x up to and including OTRS 7.0.7, OTRS 6.0.x up to and including 6.0.19 and OTRS 5.0.x up to and including 5.0.36.

 

This vulnerability is fixed in the latest versions of OTRS, and it is recommended to upgrade to the latest patch level. A new config option named ExternalFrontend::TicketDetailView###DisplayNoteFrom (Ticket::Frontend::CustomerTicketZoom###DisplayNoteFrom in OTRS 6 and below) has been added, which controls if agent information should be displayed in external note sender field, or be substituted with a different generic name. Another option named ExternalFrontend::TicketDetailView###DefaultAgentName (Ticket::Frontend::CustomerTicketZoom###DefaultAgentName in OTRS 6 and below) can be used to define the generic agent name used in the latter case. By default, previous behavior is preserved, in which agent information is divulged in the external note From field, for the sake of backwards compatibility.

Fixed releases can be found at:
