Name of the Vulnerable Software and Affected Versions Apache Traffic Server versions 9.0.0 through 9.2.10 Apache Traffic Server versions 10.0.0 through 10.0.6

Description The issue arises when the ACL configured in ip allow.config or remap.config does not utilize IP addresses provided by the PROXY protocol. A new setting, proxy.config.acl.subjects, can be used to select which IP addresses to use for the ACL when Apache Traffic Server is set up to accept the PROXY protocol.
