Security Bulletin PBS10-01

Recommended Posts


Altair Engineering is releasing this advisory to customers running PBS Professional to alert them to a security vulnerability. This vulnerability only affects customers who supply user passwords on the command line via “qsub –Wpwd=<password>”. To the best of our knowledge, this vulnerability is not publicly known at this time.

An attacker who successfully exploits this vulnerability could gain access to a PBS user’s password on the system or systems running PBS Professional, thus allowing the attacker to perform actions as that user.



Although we do not view this vulnerability as Critical, we take security very seriously, and recommend that customers who find themselves vulnerable to this defect, that is, those using the “qsub –W pwd=<password>” command, apply this update in a timely fashion.
