Name of the Vulnerable Software and Affected Versions
Cisco Secure Client versions 4.9.00086 and earlier
Description
A vulnerability in the interprocess communication (IPC) channel of Cisco Secure Client for Windows could allow an authenticated, local attacker to perform a DLL hijacking attack on an affected device if the Secure Firewall Posture Engine, formerly HostScan, is installed on Cisco Secure Client. This vulnerability is due to insufficient validation of resources that are loaded by the application at run time. An attacker could exploit this vulnerability by sending a crafted IPC message to a specific Cisco Secure Client process. A successful exploit could allow the attacker to execute arbitrary code on the affected machine with SYSTEM privileges. To exploit this vulnerability, the attacker must have valid user credentials on the Windows system.
Recommendations
Update to version 5.1.8.105 or later to resolve the issue. As a temporary workaround, consider restricting access to the Secure Firewall Posture Engine or disabling the vulnerable IPC channel until a patch is available. Avoid using the affected Cisco Secure Client process until the issue is resolved.
Correção
LPE
Improper Verification of Cryptographic Signature
