CVE-2022-45060

Disclosure Date: November 09, 2022 •
CVE-2022-45060 CVSS v3 Base Score: 7.5
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

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.
