NOTE: This vulnerability is only applicable to AR System on Linux servers.

 

BMC Software has identified a security vulnerability (CVE-2018-19647) that could allow a remote, unauthenticated attacker to gain arbitrary code execution as the system user. The exposure is limited to scenarios where an attacker is on the same network as Remedy AR System and has the capability to bypass standard network based defenses such as firewalls.

All service packs and patches of Remedy AR System 9.x and 18.x versions are affected by this vulnerability.

BMC strongly recommends that customers who have installed Remedy AR System 9.x or 18.x on a Linux server apply this hotfix.

 

Hot fixes for the affected versions are available at the following links:

 

Note on prerequisites: On some versions, patches need to be applied prior to applying the hot fix (if they have not been already applied)

  • For 9.1.04, patch 002 (9.1.04.002).
  • For 9.1.03, patch 001 (9.1.03.001)
  • For 9.1.02, patch 004 (9.1.02.004)

There are no prerequisites for installation on Remedy AR System 18.05 or 18.08.

 

Thanks to François Goichon from the Google Security Team for identification of this problem.
