TITLE:
Cisco Service Control Engine SSH Server Denial of Service
Vulnerabilities

SECUNIA ADVISORY ID:
SA30316

VERIFY ADVISORY:
http://secunia.com/advisories/30316/

CRITICAL:
Moderately critical

IMPACT:
DoS

WHERE:
>From remote

OPERATING SYSTEM:
Cisco SCE 1000 Series (Service Control Engine)
http://secunia.com/product/18751/
Cisco SCE 2000 Series (Service Control Engine)
http://secunia.com/product/18752/

DESCRIPTION:
Some vulnerabilities have been reported in Cisco Service Control
Engine, which can be exploited by malicious people to cause a DoS
(Denial of Service).

1) An unspecified error within the SCE SSH server can be exploited to
cause system instability or a reload of the SCE via certain SSH login
activity.

2) An unspecified error during the login process within the SCE SSH
server can be exploited to cause a DoS via specific SSH credentials
that attempt to change the authentication method.

Vulnerabilities #1 and #2 are reported in the SCE 1000 and 2000
series with software versions prior to 3.1.6.

3) An unspecified error within the SCE SSH server when processing SSH
traffic to the SCE management interface can lead to an illegal IO
operation and an imperative reboot of the SCE.

Vulnerability #3 is reported in the SCE 1000 and 2000 series with
software versions prior to 3.0.7 and 3.1.0.

Successful exploitation of these vulnerabilities requires that the
SSH server is enabled (not enabled by default).

SOLUTION:
Update to version 3.1.6.
