{"id":"GHSA-47xh-qxqv-mgvg","summary":"kube-httpcache is vulnerable to Cross-Site Request Forgery (CSRF)","details":"### Impact\n\n\u003e 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\u003e -- 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","modified":"2022-12-02T22:24:44Z","published":"2022-12-02T22:24:44Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2022-12-02T22:24:44Z","nvd_published_at":null,"cwe_ids":["CWE-352"],"severity":"MODERATE"},"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"}],"affected":[{"package":{"name":"github.com/mittwald/kube-httpcache","ecosystem":"Go","purl":"pkg:golang/github.com/mittwald/kube-httpcache"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.7.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/12/GHSA-47xh-qxqv-mgvg/GHSA-47xh-qxqv-mgvg.json"}}],"schema_version":"1.9.0"}
