PHP CGI module may misinterpret those characters as PHP options, which may allow a malicious user to pass options to PHP binary being run, and thus reveal the source code of scripts, run arbitrary PHP code on the server, etc.","published":"2024-06-09T19:42:36.464Z","modified":"2026-10-21T02:30:51.604605353Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.99987,"percentile":0.99983,"asOf":"2026-09-16"},"cisaKev":{"dateAdded":"2024-06-12","dueDate":"2024-07-03","knownRansomwareCampaignUse":true},"exploitsKnown":56,"affectedPackages":[{"ecosystem":"Bitnami","name":"libphp","fixedVersion":"8.1.29"}],"fix":{"url":"https://github.com/rapid7/metasploit-framework/pull/19247","label":"rapid7/metasploit-framework#19247"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/06/07/1"},{"type":"WEB","url":"https://arstechnica.com/security/2024/06/php-vulnerability-allows-attackers-to-run-malicious-code-on-windows-servers/"},{"type":"WEB","url":"https://isc.sans.edu/diary/30994"},{"type":"WEB","url":"https://labs.watchtowr.com/no-way-php-strikes-again-cve-2024-4577/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/PKGTQUOA2NTZ3RXN22CSAUJPIRUYRB4B/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/W45DBOH56NQDRTOM2DN2LNA2FZIMC3PK/"},{"type":"WEB","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2024-4577"},{"type":"WEB","url":"https://www.php.net/ChangeLog-8.php#8.1.29"},{"type":"WEB","url":"https://www.php.net/ChangeLog-8.php#8.2.20"},{"type":"WEB","url":"https://www.php.net/ChangeLog-8.php#8.3.8"},{"type":"WEB","url":"https://www.vicarius.io/vsociety/posts/php-cgi-argument-injection-to-rce-cve-2024-4577"},{"type":"WEB","url":"https://www.vicarius.io/vsociety/posts/php-cgi-os-command-injection-vulnerability-cve-2024-4577"},{"type":"ADVISORY","url":"https://cert.be/en/advisory/warning-php-remote-code-execution-patch-immediately"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/4xxx/CVE-2024-4577.json"},{"type":"ADVISORY","url":"https://github.com/php/php-src/security/advisories/GHSA-3qgc-jrrr-25jv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-4577"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20240621-0008/"},{"type":"FIX","url":"https://github.com/rapid7/metasploit-framework/pull/19247"},{"type":"PACKAGE","url":"https://github.com/11whoami99/CVE-2024-4577"},{"type":"PACKAGE","url":"https://github.com/php/php-src"},{"type":"PACKAGE","url":"https://github.com/watchtowrlabs/CVE-2024-4577"},{"type":"PACKAGE","url":"https://github.com/xcanwin/CVE-2024-4577-PHP-RCE"},{"type":"ARTICLE","url":"https://blog.orange.tw/2024/06/cve-2024-4577-yet-another-php-rce.html"},{"type":"ARTICLE","url":"https://blog.talosintelligence.com/new-persistent-attacks-japan/"},{"type":"ARTICLE","url":"https://devco.re/blog/2024/06/06/security-alert-cve-2024-4577-php-cgi-argument-injection-vulnerability-en/"},{"type":"ARTICLE","url":"https://www.imperva.com/blog/imperva-protects-against-critical-php-vulnerability-cve-2024-4577/"}],"provenance":{"sources":["OSV.dev","CISA KEV","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T02:30:51.604605353Z"}}
