Veritas has patched a security flaw in its Java authentication service running on the firm’s NetBackup products.
The vulnerability potentially allows remote hackers to gain access to information stored on back-up servers and clients.
This is the third Veritas back-up security flaw in around four months, and comes just after security firm Symantec completed its acquisition of the company in a multi-billion dollar deal.
Veritas said NetBackup versions 4.5, 5.0, 5.1 and 6.0 running on all platforms are affected by the threat.
No exploit code for the latest vulnerability has so far appeared on the internet, but recent Veritas flaws led to customers being targeted by hackers.
