VAR-200210-0279
Vulnerability from variot - Updated: 2025-04-03 22:14Cisco Virtual Private Network (VPN) Client software 2.x.x, and 3.x before 3.6(Rel), when configured with all tunnel mode, can be forced into acknowledging a TCP packet from outside the tunnel. This has the potential to leak information about the client system to attackers. This issue does not occur if "split tunneling mode" is enabled. Furthermore, 3.5.x releases of the client are not prone to this issue if the firewall is configured to run in "always on" mode. The 3.6(Rel) version of the client is prone to this issue even under circumstances where the firewall is run in "always on" mode. It can be used under the Microsoft Windows operating system, and can also be used under the Linux operating system. affected by this vulnerability. CISCO designated this vulnerability number as: CSCdy37058
