Detection & IOCsextracted from sources · hover to see the quote
- →Exploit vector is a crafted HTTP Host header used for header smuggling against Squid's mime_get_header_field() function; monitor for malformed or unexpected Host header values in HTTP requests processed by Squid acting as interception or reverse-proxy ↗
- →The vulnerability resides in mime_header.cc (mime_get_header_field() function) in Squid before 3.5.18; target detection at Squid versions < 3.5.18 ↗
- →Attack can also be used for cache poisoning against clients not following RFC 7230; inspect Squid cache for unexpected or cross-origin content injected via manipulated Host headers ↗
- ·Squid must be operating in interception or reverse-proxy mode for the same-origin bypass impact to apply; standard forward-proxy deployments may have different exposure ↗
- ·Red Hat Enterprise Linux 5 will NOT receive a fix for this CVE; deployments on RHEL 5 remain permanently vulnerable ↗
- ·Vendor-supplied patches exist for multiple Squid branches (3.1, 3.3, 3.4, 3.5) at the squid-cache.org advisory page; apply the branch-appropriate patch if upgrading to 3.5.18+ is not immediately possible ↗

squid: Header Smuggling issue in HTTP Request processing
mime_header.cc in Squid before 3.5.18 allows remote attackers to bypass intended same-origin restrictions and possibly conduct cache-poisoning attacks via a crafted HTTP Host header, aka a "header smuggling" issue.
An input validation flaw was found in Squid's mime_get_header_field() function, which is used to search for headers within HTTP requests. An attacker could send an HTTP request from the client side with specially crafted header Host header that bypasses same-origin security protections, causing Squid operating as interception or reverse-proxy to contact the wrong origin server. It could also be used for cache poisoning for client not following RFC 7230.
