A problem with the Palo Alto Networks GlobalProtect app can result in exposure of encrypted user credentials, used for connecting to GlobalProtect, in application logs. Normally, these application logs are only viewable by local users and are included when generating logs for troubleshooting purposes. This means that these encrypted credentials are exposed to recipients of the application logs.
DHCP can add routes to a client’s routing table via the classless static route option (121). VPN-based security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic that was expected to be protected by the VPN.
