Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Github.com/mittwald/kube httpcache, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact > 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. > -- https://varnish-cache.org/security/VSV00011.html#vsv00011 ### Patches This is fixed in Varnish 6.0.11; Varnish 6.0.11 is available in `kube-httpcache` versions v0.7.1 and later. ### Workarounds See [upstream mitigation hints](https://varnish-cache.org/security/VSV00011.html#mitigation). ### References - https://varnish-cache.org/security/VSV00011.html#vsv00011
