Cisco Unified Computing System Software contains a vulnerability that could allow an unauthenticated, remote attacker to gain unauthorized access to a targeted system. Updates are available.
Cisco Unified Computing System Software contains a vulnerability that could allow an unauthenticated, remote attacker to gain unauthorized access to a targeted system.
The vulnerability is due to improper processing of authentication requests. An unauthenticated, remote attacker could exploit this vulnerability by sending malicious requests to the system.
Cisco has confirmed the vulnerability in a security advisory and has released software updates.
Cisco Unified Computing System versions prior to 1.0(2h), prior to 1.1(1j), and all 1.3 versions are vulnerable when configured to use Lightweight Directory Access Protocol (LDAP) authentication.
Attackers must be able to send login requests to the web-based management console to exploit the vulnerability. Depending on network access restrictions, attackers may require access to authorized systems to launch an exploit.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
An unauthenticated, remote attacker could exploit this vulnerability to gain unauthorized access to the affected application with the privileges of another system user, allowing the attacker to take actions in the application as the targeted user.
The vulnerability is due to improper handling of requests by the Cisco Unified Computing System Manager Web Console login page. Only applications configured to use LDAP authentication providers are affected.
An unauthenticated, remote attacker could exploit this vulnerability by sending malicious login requests to the web-based management console. The processing of the requests could grant the attacker unauthorized access to the application with the privileges of an arbitrary user.
Administrators are advised to apply the appropriate updates.
Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
Administrators are advised to monitor affected systems.
