Vulnerable Products
+------------------
Cisco Unified Communication Manager 5.0/5.1 versions prior to 5.1(3a)
and 6.0/6.1 versions prior to 6.1(1a) are affected by this
vulnerability.
The software version of a CallManager or Unified Communications
Manager system can be determined by navigating to Show > Software via
the administration interface.
For Unified Communications Manager, the software version can also be
determined by running the show version active command in the Command
Line Interface (CLI).
Products Confirmed Not Vulnerable
+--------------------------------
Cisco CallManager or Unified Communication Manager systems prior to
5.0 are not affected by this vulnerability. No 3.x and 4.x releases
are vulnerable.
No other Cisco products are known to be affected by this
vulnerability.
Details
=======
Cisco Unified CallManager/Communications Manager (CUCM) is the call
processing component of the Cisco IP telephony solution. This
solution extends enterprise telephony features and functions to
packet telephony network devices such as IP phones, media processing
devices, voice-over-IP (VoIP) gateways, and multimedia applications.
An attacker can trigger this SQL injection vulnerability by entering
a specially crafted value is entered in the key parameter of either
the admin or user interface page. Attacks against this vulnerability
are conducted through the web interface and use the http or https
protocol. A successful attack could terminate a SQL call and force a
connection to the back-end database resulting in the disclosure of
potentially sensitive information such as usernames and password
hashes.
This vulnerability is documented as bug ID CSCsk64286
Vulnerability Scoring Details
=============================
Cisco has provided scores for the vulnerabilities in this advisory
based on the Common Vulnerability Scoring System (CVSS). The CVSS
scoring in this Security Advisory is performed in accordance with
CVSS version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability
severity and helps determine urgency and priority of response.
Cisco has provided a base and temporal score. Customers can then
compute environmental scores to assist in determining the impact of
the vulnerability in individual networks.
Cisco has provided an FAQ to answer additional questions regarding
CVSS at
