xinetd is vulnerable to authorization bypass. The service type is not verified in builtins.c
when the TCPMUX
or TCPMUXPLUS
type and tcpmux-server
service are enabled. This exposes all enabled services and allows remote attackers to bypass access and firewall restrictions via a request to tcpmux
port 1.
