Although the Referer header is sanitized by escaping some characters that can allow XSS (e.g., [&], [<], [>], [\"], [']), it does not account for the attack based on the JavaScript URL scheme (e.g., javascript:alert(document.domain)// payload). Exploiting this vulnerability may not be trivial, but it could lead to the execution of malicious scripts in the context of the target user’s browser, compromising user sessions.","affected":[{"package":{"name":"github.com/greenpau/caddy-security","ecosystem":"Go","purl":"pkg:golang/github.com/greenpau/caddy-security"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"1.1.23"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/02/GHSA-ff72-ff42-c3gw/GHSA-ff72-ff42-c3gw.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-21496"},{"type":"WEB","url":"https://github.com/greenpau/caddy-security/issues/267"},{"type":"WEB","url":"https://blog.trailofbits.com/2023/09/18/security-flaws-in-an-sso-plugin-for-caddy"},{"type":"WEB","url":"https://security.snyk.io/vuln/SNYK-GOLANG-GITHUBCOMGREENPAUCADDYSECURITY-6249860"},{"type":"PACKAGE","url":"github.com/greenpau/caddy-security"}],"database_specific":{"cwe_ids":["CWE-79"],"github_reviewed":true,"github_reviewed_at":"2024-02-20T23:46:51Z","nvd_published_at":"2024-02-17T05:15:09Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N"}]} |
