CVE-2014-8422: Unify Openscape Desk Phone IP SIP

High severity, CVSS 8.1. EPSS: 1.6% chance of exploitation in the next 30 days.

The web-based management (WBM) interface in Unify (former Siemens) OpenStage SIP and OpenScape Desk Phone IP V3 devices before R3.32.0 generates session cookies with insufficient entropy, which makes it easier for remote attackers to hijack sessions via a brute-force attack.

• Unify Openstage SIP: before r3.32.0 (fixed in r3.32.0)
