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.
