{"id":"CVE-2024-21496","aliases":["GO-2024-2559"],"url":"https://o3.security/vulnerability/CVE-2024-21496","summary":"Cross-site Scripting in github.com/greenpau/caddy-security","details":"All versions of the package github.com/greenpau/caddy-security are vulnerable to Cross-site Scripting (XSS) via the Referer header, due to improper input sanitization. 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.","published":"2024-02-17T06:30:34Z","modified":"2024-11-06T23:31:23Z","cvss":{"score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/greenpau/caddy-security","fixedVersion":null}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2024-11-06T23:31:23Z"}}
