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 running the arplugin service. The exposure is limited to scenarios where an attacker is on the same network as the Remedy AR System and can bypass standard network-based defenses such as firewalls. For Remedy AR System 9.x and 18.x, all versions, service packs, and patches are affected by this vulnerability. BMC strongly recommends that customers who have installed Remedy AR System 9.x or 18.x apply this hot fix. Hot fixes for the affected versions are available at the following links:

 

 

PREREQUISITES: Customers on Remedy AR System 9.1.04 must apply patch 002 (9.1.04.002) before applying the hot fix if they have not already applied it. Customers on Remedy AR System 9.1.03 must apply patch 001 (9.1.03.001) before applying the hot fix if they have not already applied it. Customers on Remedy AR System 9.1.02 must apply patch 004 (9.1.02.004) before applying the hot fix if they have not already applied it. 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.
