| Description: | Summary:
The remote host is missing an update for the Debian 'otrs2' package(s) announced via the DLA-3551-1 advisory.
Vulnerability Insight:
Multiple vulnerabilities were found in otrs2, the Open-Source Ticket Request System, which could lead to impersonation, denial of service, information disclosure, or execution of arbitrary code.
CVE-2019-11358
A Prototype Pollution vulnerability was discovered in OTRS' embedded jQuery 3.2.1 copy, which could allow sending drafted messages as wrong agent.
This vulnerability is also known as OSA-2020-05.
CVE-2019-12248
Matthias Terlinde discovered that when an attacker sends a malicious email to an OTRS system and a logged in agent user later quotes it, the email could cause the browser to load external image resources.
A new configuration setting Ticket::Frontend::BlockLoadingRemoteContent has been added as part of the fix. It controls whether external content should be loaded, and it is disabled by default.
This vulnerability is also known as OSA-2019-08.
CVE-2019-12497
Jens Meister discovered that in the customer or external frontend, personal information of agents, like Name and mail address in external notes, could be disclosed.
New configuration settings Ticket::Frontend::CustomerTicketZoom###DisplayNoteFrom has been added as part of the fix. It controls if agent information should be displayed in external note sender field, or be substituted with a different generic name. Another option named Ticket::Frontend::CustomerTicketZoom###DefaultAgentName can then 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.
This vulnerability is also known as OSA-2019-09.
