Title: Cray UNICOS NQS Daemon Format String Vulnerability
Severity: CRITICAL
Description:
UNICOS is the supercomputer operating system distributed by Cray. It is typically used with Cray systems.
A problem in UNICOS makes it possible for a local user to gain unauthorized privileges. The problem is in the nqsdaemon.
nqsdaemon is part of the Network Queueing System, a program designed to distribute computing load amongst homogenous systems on a network. It functions by loading shell script with NQS tags, then processing the shell scripts.
nqsdaemon doesn't not correctly handle some file names. Upon loading of a shell script by the nqsdaemon that contains format strings, it is possible to execute arbitrary code. Since the nqsdaemon runs as root, the executed code would be in the context of the root user.
This problem makes it possible for local users to gain elevated privileges, and compromise administrative access to a vulnerable system.
Affected Products:
- Cray UNICOS/mk 2.0.5.54
