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.","lang":"en"}],"references":[{"url":"https://security.snyk.io/vuln/SNYK-GOLANG-GITHUBCOMGREENPAUCADDYSECURITY-6249860"},{"url":"https://github.com/greenpau/caddy-security/issues/267"},{"url":"https://blog.trailofbits.com/2023/09/18/security-flaws-in-an-sso-plugin-for-caddy/"}],"affected":[{"product":"github.com/greenpau/caddy-security","versions":[{"version":"0","lessThan":"*","status":"affected","versionType":"semver"}],"vendor":"n/a"}]},"adp":[{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-79","lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')"}]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-02-20T15:37:01.746124Z","id":"CVE-2024-21496","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-11-06T18:53:52.043Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-01T22:20:40.901Z"},"title":"CVE Program Container","references":[{"url":"https://security.snyk.io/vuln/SNYK-GOLANG-GITHUBCOMGREENPAUCADDYSECURITY-6249860","tags":["x_transferred"]},{"url":"https://github.com/greenpau/caddy-security/issues/267","tags":["x_transferred"]},{"url":"https://blog.trailofbits.com/2023/09/18/security-flaws-in-an-sso-plugin-for-caddy/","tags":["x_transferred"]}]}]}}
