Cisco Unified Communications Manager contains a vulnerability that could allow an authenticated remote attacker to conduct Structured Query Language injection attacks on a targeted device. Updates are not available.
A vulnerability in Cisco Unified Communication Manager (Unified CM) could allow an authenticated, remote attacker to execute a blind Structured Query Language (SQL) injection.
The vulnerability is due to improper validation of user-supplied requests by the Cisco Unified CM. An attacker could exploit this vulnerability by injecting SQL commands, which could allow the attacker to insert rows within the database.
Proof-of-concept code that demonstrates an exploit of this vulnerability is publicly available.
Cisco has confirmed the vulnerability in a security advisory; however, software updates are not yet available.
Cisco Unified CM versions 9.1(2) and prior are affected.
To exploit this vulnerability, an attacker requires authenticated access to the targeted system. Authenticated access may require the attacker to access trusted, internal networks. These access requirements could limit the likelihood of a successful exploit.
Cisco Unified CM version 8.0 reached the End of Software Maintenance on October 23, 2012. Customers using Cisco Unified CM 8.0(x) versions should contact their Cisco support team for assistance in upgrading to a supported version of Cisco Unified CM.
Cisco Unified CM is the only product confirmed to be vulnerable. Additional voice products may be affected by one or more of the individual vulnerabilities that are described in the advisory. The following products are being investigated but have not yet been confirmed as vulnerable:
Cisco Emergency Responder
Cisco Unified Contact Center Express
Cisco Unified Customer Voice Portal
Cisco Unified Presence Server/Cisco IM and Presence Service
Cisco Unity Connection
This vulnerability can be exploited over the default management ports, TCP port 8080 or 8443.
An authenticated, remote attacker could exploit the vulnerability to modify or insert crafted data in certain tables within the Cisco Unified CM database, which could allow an attacker to use the malicious data in additional attacks.
The vulnerability is due to improper validation of user-supplied input by the affected software when handling SQL queries.
An authenticated, remote attacker could exploit the vulnerability by submitting crafted SQL queries to a targeted device. When the affected software processes the malicious SQL queries, the attacker could modify or insert crafted data into certain tables within the Cisco Unified CM database, which could allow an attacker to use the malicious data in additional attacks.
Administrators are advised to contact the vendor regarding future updates and releases.
The security vulnerability applies to the following combinations of products.
Cisco Unified Communications Manager
7.1 Base, (3), (5), (5b) | 8.0 Base, (2c), (3) | 8.5 Base | 8.6 Base | 9.0 Base | 9.0(1) Base | 9.1 Base | 9.1(1) Base
