Description:

HipChat Server used a vulnerable version of the ImageMagick library
without restricting coders. Attackers who can log in can use the
ImageMagick vulnerabilities in vulnerable versions of HipChat Server
to:

* Execute remote code of their choice
* Delete files that the www-data user has permission to delete
* Move files that the www-data user has permission to move
* Read files that the www-data user has permission to read
* Make http requests to local and internal services

To exploit this issue, attackers need to have a valid account in a
vulnerable HipChat Server instance.

All versions of HipChat Server before version 2.0 build 1.4.1 are
affected by this vulnerability. This issue can be tracked here:
https://jira.atlassian.com/browse/BAM-17099


Fix:

We have taken the following steps to address these issues:
Released HipChat Server version 2.0 build 1.4.1 that contains fixes
for these issues. As of version 2.0 build 1.4.1 -
* HipChat Server checks if a file is a supported image format before
passing the file to the ImageMagick library.
* HipChat Server uses a policy file to disable vulnerable ImageMagick coders.

Remediation:
Upgrade HipChat Server to version 2.0 build 1.4.1 or higher.
