CVE-2023-20241

Name of the Vulnerable Software and Affected Versions Cisco Secure Client Software (affected versions not specified)

Description The issue is related to multiple vulnerabilities in Cisco Secure Client Software that could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected system. These vulnerabilities are due to an out-of-bounds memory read from Cisco Secure Client Software. An attacker could exploit these vulnerabilities by logging in to an affected device at the same time that another user is accessing Cisco Secure Client on the same system, and then sending crafted packets to a port on that local host. A successful exploit could allow the attacker to crash the VPN Agent service, causing it to be unavailable to all users of the system. To exploit these vulnerabilities, the attacker must have valid credentials on a multi-user system.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
