Advisory Content : NSFOCUS Security Advisory(SA2007-02) Topic: Cisco Security Agent Remote Buffer Overflow Vulnerability Release Date: 2007-12-06 CVE CAN ID : CVE-2007-5580 Affected system: ============== Cisco Security Agent for Windows < 4.5.1.672 Cisco Security Agent for Windows < 5.0.0.225 Cisco Security Agent for Windows < 5.1.0.106 Cisco Security Agent for Windows < 5.2.0.238 Unaffected system: ============== Impact: ====== NSFOCUS Security Team discovered a remote buffer overflow vulnerability in Cisco Security Agent for Windows which allows remote code execution by sending a malicious SMB request. Description: ========== Cisco Security Agent is a security software agent that provides threat protection for server and desktop computing systems. A driver bundled with Cisco Security Agent for Windows does not correctly check the data length provided by users when processing a SMB packet, which might trigger a stack buffer overflow in the system kernel. A remote attacker might cause system with CSA installed to restart or BSOD. By sending carefully crafted data an attacker might cause remote code execution, thus gains complete control over the system. By default CSA allows access to TCP ports 139 and 445. After establishing a session to TCP ports 139 and 445, an attacker can complete an exploitation without any authentication simply by sending a single packet. Cisco Security Agent for Windows version 5.2.0.225 and prior are affected. Other Cisco software that uses CSA component is also affected. Workaround: =========== * Restrict access to TCP ports 139 and 445. Vendor Status: ============ 2007.09.27 Informed the vendor 2007.10.23 Vendor confirmed the vulnerability 2007.12.05 Vendor released a security advisory (cisco-sa-20071205-csa) and related patches.
