Unify (former Siemens) OpenStage SIP and OpenScape Desk Phone IP V3 devices before R3.32.0 allow remote attackers to gain super-user privileges by leveraging SSH access and incorrect ownership of (1) ConfigureCoreFile.sh, (2) Traceroute.sh, (3) apps.sh, (4) conversion_java2native.sh, (5) coreCompression.sh, (6) deletePasswd.sh, (7) findHealthSvcFDs.sh, (8) fw_printenv.sh, (9) fw_setenv.sh, (10) hw_wd_kicker.sh, (11) new_rootfs.sh, (12) opera_killSnmpd.sh, (13) opera_startSnmpd.sh, (14) rebootOperaSoftware.sh, (15) removeLogFiles.sh, (16) runOperaServices.sh, (17) setPasswd.sh, (18) startAccTestSvcs.sh, (19) usbNotification.sh, or (20) appWeb in /Opera_Deploy.

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.

CRLF injection vulnerability in the web-based management (WBM) interface in Unify (former Siemens) OpenStage SIP and OpenScape Desk Phone IP V3 devices before R3.32.0 allows remote authenticated users to modify the root password and consequently access the debug port using the serial interface via the ssh-password parameter to page.cmd.

OpenStage 60 and OpenScape Desk Phone IP 55G SIP V3, OpenStage 15, 20E, 20 and 40 and OpenScape Desk Phone IP 35G SIP V3, OpenScape Desk Phone IP 35G Eco SIP V3, OpenStage 60 and OpenScape Desk Phone IP 55G HFA V3, OpenStage 15, 20E, 20, and 40 and OpenScape Desk Phone IP 35G HFA V3, and OpenScape Desk Phone IP 35G Eco HFA V3 use non-unique X.509 certificates and SSH host keys.
