{"id":"CVE-2024-21493","aliases":["GO-2024-2564"],"url":"https://o3.security/vulnerability/CVE-2024-21493","summary":"Improper Validation of Array Index in github.com/greenpau/caddy-security","details":"All versions of the package github.com/greenpau/caddy-security are vulnerable to Improper Validation of Array Index when parsing a Caddyfile. Multiple parsing functions in the affected library do not validate whether their input values are nil before attempting to access elements, which can lead to a panic (index out of range). Panics during the parsing of a configuration file may introduce ambiguity and vulnerabilities, hindering the correct interpretation and configuration of the web server.","published":"2024-02-17T06:30:34Z","modified":"2024-06-28T15:58:30.931249Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":{"score":0.00722,"percentile":0.51467,"asOf":"2026-08-31"},"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-2024-21493"},{"type":"WEB","url":"https://github.com/greenpau/caddy-security/issues/263"},{"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-5961078"},{"type":"PACKAGE","url":"github.com/greenpau/caddy-security"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2024-06-28T15:58:30.931249Z"}}
