{"id":"GHSA-47xh-qxqv-mgvg","aliases":[],"url":"https://o3.security/vulnerability/GHSA-47xh-qxqv-mgvg","summary":"kube-httpcache is vulnerable to Cross-Site Request Forgery (CSRF)","details":"### Impact\n\n> 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.\n> -- https://varnish-cache.org/security/VSV00011.html#vsv00011\n\n### Patches\n\nThis is fixed in Varnish 6.0.11; Varnish 6.0.11 is available in `kube-httpcache` versions v0.7.1 and later.\n\n### Workarounds\n\nSee [upstream mitigation hints](https://varnish-cache.org/security/VSV00011.html#mitigation).\n\n### References\n\n- https://varnish-cache.org/security/VSV00011.html#vsv00011\n\n","published":"2022-12-02T22:24:44Z","modified":"2022-12-02T22:24:44Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/mittwald/kube-httpcache","fixedVersion":"0.7.1"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/mittwald/kube-httpcache/security/advisories/GHSA-47xh-qxqv-mgvg"},{"type":"PACKAGE","url":"https://github.com/mittwald/kube-httpcache"},{"type":"WEB","url":"https://varnish-cache.org/security/VSV00011.html#vsv00011"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2022-12-02T22:24:44Z"}}
