Version Summary: Cisco Unity Connection contains a vulnerability that could
allow an authenticated, remote attacker to conduct a SQL injection attack.
Updates are not available.
Description
A vulnerability in the web interface of Cisco Unity Connection (UC) could
allow an authenticated, remote attacker to impact the confidentiality of the
system by executing arbitrary SQL queries.
The vulnerability is due to a lack of input validation on user-supplied input
in SQL queries. An attacker could exploit this vulnerability by entering a
maliciously crafted value containing SQL commands as an HTTP POST request
parameter. An exploit could allow the attacker to determine the presence of
certain values in the database.
Cisco has confirmed the vulnerability; however, software updates are not
available.
Warning Indicators
At the time this alert was first published, Cisco Unity Connection versions
9.1(1.2) and prior were vulnerable. Later versions may also be vulnerable.
[Updated!] IntelliShield Analysis
To exploit this vulnerability, an attacker must authenticate to the targeted
device. This access requirement may reduce the likelihood of a successful
exploit.
Cisco indicates through the CVSS score that functional exploit code exists;
however, the code is not known to be publicly available.
This vulnerability was reported to Cisco by Paul Heneghan from NCIA/NCIRC.
Vendor Announcements
Cisco has released bug ID CSCuv63824 for registered users, which contains
additional details and an up-to-date list of affected product versions.
Impact
An authenticated, remote attacker could exploit this vulnerability to access a
subset of sensitive information stored in the database on an affected device.
A successful exploit could be used to conduct further attacks.
Technical Information
The vulnerability is due to improper validation of user-supplied input for SQL
queries on an affected device.
An authenticated, remote attacker could exploit this vulnerability by entering
a crafted value containing SQL commands as an HTTP POST request. An exploit
could allow the attacker to determine certain values in the database of the
targeted device, resulting in a SQL injection attack.
Safeguards
Administrators are advised to contact the vendor regarding future updates and
releases.
Administrators are advised to allow only trusted users to have network access.
Administrators are advised to allow only privileged users to access
administration or management systems.
