DISPUTED Squid 3.1.9 allows remote attackers to bypass the access
configuration for the CONNECT method by providing an arbitrary allowed
hostname in the Host HTTP header. NOTE: this issue might not be
reproducible, because the researcher is unable to provide a squid.conf file
for a vulnerable system, and the observed behavior is consistent with a
squid.conf file that was (perhaps inadvertently) designed to allow access
based on a “req_header Host” acl regex that matches www.uol.com.br.
Notes
| Author | Note |
|---|---|
| mdeslaur | Need to check, see reproducer in original post |
| sbeattie | dropping to low, as it requires a specific configuration using Host header filtering also, upstream does not have a fix for this. |
| seth-arnold | still unable to find a configuration that could demonstrate the problem; as of 2013-01-28, no fix from upstream either. |
| mdeslaur | Disputed, so ignored. |
