An argument injection vulnerability has been identified in the administrative web interface of the Atos Unify OpenScape products "Session Border Controller" (SBC) and "Branch", before version V10 R3.4.0, and OpenScape "BCF" before versions V10R10.12.00…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.86%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An argument injection vulnerability has been identified in the administrative web interface of the Atos Unify OpenScape products "Session Border Controller" (SBC) and "Branch", before version V10 R3.4.0, and OpenScape "BCF" before versions V10R10.12.00 and V10R11.05.02. This allows an unauthenticated attacker to gain root access to the appliance via SSH (scope change) and also bypass authentication for the administrative interface and gain access as an arbitrary (administrative) user.
