VAR-200304-0128

Vulnerability from variot - Updated: 2025-04-03 22:24

Buffer overflows in the Cisco VPN 5000 Client before 5.2.7 for Linux, and VPN 5000 Client before 5.2.8 for Solaris, allow local users to gain root privileges via (1) close_tunnel and (2) open_tunnel. The condition affects the binaries 'close_tunnel' and 'open_tunnel', both installed setuid root by default. Malicious local users may exploit these vulnerabilities to gain superuser privileges on the affected host. Cisco Virtual Private Network (VPN) client program is a program used to securely communicate with enterprise CISCO VPN devices through the Internet. It can be used under the Microsoft Windows operating system, and can also be used under the Linux operating system. CISCO assigned this vulnerability number as: CSCdy20065 < link: http://www.cisco.com/warp/public/707/vpn5k-client-multiple-vuln-pub.shtml >
