CVE-2022-45060

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.

This is Varnish Cache, a web application accelerator also known as a caching HTTP reverse proxy. You install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast. It typically speeds up delivery with a factor of 300 - 1000x, depending on your architecture.

This update for varnish fixes the following issues:

Update to 7.2.1:

• CVE-2022-45059: Fixed a HTTP request smuggling via hop-by-hop headers (boo#1205243).
• CVE-2022-45060: Fixed a HTTP request forgery via character injection through HTTP/2 pseudo-headers (boo#1205242).

These are all security issues fixed in the libvarnishapi3-7.2.1-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the libvinylapi3-9.0.0-1.1 package on the GA media of openSUSE Tumbleweed.

Martin van Kervel Smedshammer discovered that Varnish did not properly sanitize certain HTTP headers. A remote attacker could possibly use this issue to perform a cross-site request forgery (CSRF) attack.
