Vulnerability Summary

An HTTP Request Forgery issue exists in Varnish Cache 5.x and 6.x prior to 6.0.11, 7.x prior to 7.1.2, and 7.2.x prior to 7.2.1. An attacker may introduce characters through HTTP/2 pseudo-headers that are invalid in the context of an HTTP/1 request line, causing the Varnish server to produce invalid HTTP/1 requests to the backend. This could, in turn, be used to exploit vulnerabilities in a server behind the Varnish server. Note: the 6.0.x LTS series (prior to 6.0.11) is affected.
