{"id":"GHSA-8h95-jcp5-pjpr","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.","aliases":["CVE-2024-21493","GO-2024-2564"],"modified":"2024-06-28T15:58:30.931249Z","published":"2024-02-17T06:30:34Z","database_specific":{"nvd_published_at":"2024-02-17T05:15:08Z","cwe_ids":["CWE-129"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2024-02-20T23:47:20Z"},"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"}],"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-8h95-jcp5-pjpr/GHSA-8h95-jcp5-pjpr.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
