An issue was discovered in Varnish Cache 7.x before 7.1.2 and 7.2.x before 7.2.1. A request smuggling attack can be performed on Varnish Cache servers by requesting that certain headers are made hop-by-hop, preventing the Varnish Cache servers from forwarding critical headers to the backend.

The remote Fedora 37 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2022-0d5dcc031e advisory.

    New upstream release: A security release. This release includes fix for CVE-2022-45059 (VSV00011)  and     CVE-2022-45060 (VSV00010). From the upstream release notes:

    VSV00010 Varnish Request Smuggling Vulnerability

    Date: 2022-11-08

    A request smuggling attack can be performed on Varnish Cache servers by requesting that certain headers     are made hop-by-hop, preventing the Varnish Cache servers from forwarding critical headers to the backend.
    Among the headers that can be filtered this way are both Content-Length and Host, making it possible for     an attacker to both break the HTTP/1 protocol framing, and bypass request to host routing in VCL.

    VSV00011 Varnish HTTP/2 Request Forgery Vulnerability

    Date: 2022-11-08

    A request forgery attack can be performed on Varnish Cache servers that have the HTTP/2 protocol turned     on. An attacker may introduce characters through the 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 may in turn be used to successfully exploit vulnerabilities in a server behind the Varnish server.

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:10198-1 advisory.

  - An issue was discovered in Varnish Cache 7.x before 7.1.2 and 7.2.x before 7.2.1. A request smuggling     attack can be performed on Varnish Cache servers by requesting that certain headers are made hop-by-hop,     preventing the Varnish Cache servers from forwarding critical headers to the backend. (CVE-2022-45059)

  - An HTTP Request Forgery issue was discovered in Varnish Cache 5.x and 6.x before 6.0.11, 7.x before 7.1.2,     and 7.2.x before 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 (before 6.0.11) is affected. (CVE-2022-45060)
