TITLE:
SSH Tectia Management Agent Privilege Escalation

SECUNIA ADVISORY ID:
SA21559

VERIFY ADVISORY:
http://secunia.com/advisories/21559/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
SSH Tectia Manager 2.x
http://secunia.com/product/11677/

DESCRIPTION:
A vulnerability has been reported in SSH Tectia Manager, which can be
exploited by malicious, local users to gain escalated privileges.

Under certain circumstances, it is possible to execute a user-defined
program with escalated privileges due to an error in the management
agent component when restarting sshd. This can be exploited by
starting an unprivileged sshd program and then press the Management
server "Restart" button in Management server GUI, which results in
the unprivileged, user-specified sshd process being restarted with
"root" privileges.

Successful exploitation requires that the real managed sshd process
isn't running when the user-controlled program is executed.

The vulnerability has been reported in version 2.1.2 and prior on
Unix and Linux.

SOLUTION:
Update to version 2.1.3 or 2.2.0.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
