Cisco » Secure Access Control System : Security Vulnerabilities, CVEs, CVSS score >= 8

A vulnerability in the ACS Report component of Cisco Secure Access Control System (ACS) could allow an unauthenticated, remote attacker to execute arbitrary commands on an affected system. Commands executed by the attacker are processed at the targeted user's privilege level. The vulnerability is due to insufficient validation of the Action Message Format (AMF) protocol. An attacker could exploit this vulnerability by sending a crafted AMF message that contains malicious code to a targeted user. A successful exploit could allow the attacker to execute arbitrary commands on the ACS device. This vulnerability affects all releases of Cisco Secure ACS prior to Release 5.8 Patch 7. Cisco Bug IDs: CSCve69037.

A vulnerability in Java deserialization used by Cisco Secure Access Control System (ACS) prior to release 5.8 patch 9 could allow an unauthenticated, remote attacker to execute arbitrary commands on an affected device. The vulnerability is due to insecure deserialization of user-supplied content by the affected software. An attacker could exploit this vulnerability by sending a crafted serialized Java object. An exploit could allow the attacker to execute arbitrary commands on the device with root privileges. Cisco Bug IDs: CSCvh25988.

The web interface in Cisco Secure Access Control System (ACS) 5.x before 5.4 Patch 3 allows remote attackers to execute arbitrary operating-system commands via a request to this interface, aka Bug ID CSCue65962.

The RMI interface in Cisco Secure Access Control System (ACS) 5.x before 5.5 does not properly enforce authorization requirements, which allows remote authenticated users to obtain superadmin access via a request to this interface, aka Bug ID CSCud75180.

The RMI interface in Cisco Secure Access Control System (ACS) 5.x before 5.5 does not properly enforce authentication and authorization requirements, which allows remote attackers to obtain administrative access via a request to this interface, aka Bug ID CSCud75187.
