{"id":"CVE-2024-4577","details":"In PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, 8.3.* before 8.3.8, when using Apache and PHP-CGI on Windows, if the system is set up to use certain code pages, Windows may use \"Best-Fit\" behavior to replace characters in command line given to Win32 API functions. 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.","aliases":["BIT-libphp-2024-4577","BIT-php-2024-4577","BIT-php-min-2024-4577"],"modified":"2026-03-20T12:39:45.862632Z","published":"2024-06-09T20:15:09.550Z","related":["CGA-prg6-6rgx-hmx2","GHSA-3qgc-jrrr-25jv","openSUSE-SU-2024:14376-1"],"references":[{"type":"WEB","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2024-4577"},{"type":"ADVISORY","url":"https://www.php.net/ChangeLog-8.php#8.1.29"},{"type":"ADVISORY","url":"https://www.php.net/ChangeLog-8.php#8.2.20"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20240621-0008/"},{"type":"ADVISORY","url":"https://www.php.net/ChangeLog-8.php#8.3.8"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2024/06/07/1"},{"type":"ADVISORY","url":"https://blog.orange.tw/2024/06/cve-2024-4577-yet-another-php-rce.html"},{"type":"ADVISORY","url":"https://cert.be/en/advisory/warning-php-remote-code-execution-patch-immediately"},{"type":"ADVISORY","url":"https://www.imperva.com/blog/imperva-protects-against-critical-php-vulnerability-cve-2024-4577/"},{"type":"FIX","url":"https://github.com/rapid7/metasploit-framework/pull/19247"},{"type":"ARTICLE","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/W45DBOH56NQDRTOM2DN2LNA2FZIMC3PK/"},{"type":"ARTICLE","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/PKGTQUOA2NTZ3RXN22CSAUJPIRUYRB4B/"},{"type":"EVIDENCE","url":"https://github.com/11whoami99/CVE-2024-4577"},{"type":"EVIDENCE","url":"https://github.com/xcanwin/CVE-2024-4577-PHP-RCE"},{"type":"EVIDENCE","url":"https://labs.watchtowr.com/no-way-php-strikes-again-cve-2024-4577/"},{"type":"EVIDENCE","url":"https://blog.talosintelligence.com/new-persistent-attacks-japan/"},{"type":"EVIDENCE","url":"https://arstechnica.com/security/2024/06/php-vulnerability-allows-attackers-to-run-malicious-code-on-windows-servers/"},{"type":"EVIDENCE","url":"https://devco.re/blog/2024/06/06/security-alert-cve-2024-4577-php-cgi-argument-injection-vulnerability-en/"},{"type":"EVIDENCE","url":"https://github.com/php/php-src/security/advisories/GHSA-3qgc-jrrr-25jv"},{"type":"EVIDENCE","url":"https://www.vicarius.io/vsociety/posts/php-cgi-argument-injection-to-rce-cve-2024-4577"},{"type":"EVIDENCE","url":"https://www.vicarius.io/vsociety/posts/php-cgi-os-command-injection-vulnerability-cve-2024-4577"},{"type":"EVIDENCE","url":"https://github.com/watchtowrlabs/CVE-2024-4577"},{"type":"EVIDENCE","url":"https://isc.sans.edu/diary/30994"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/php/php-src","events":[{"introduced":"381ba9f5d0edd0c9c8ec1dea7e21d513ad08b115"},{"fixed":"fc4973fb0dfae6085742868b8f0f05163e150a0c"},{"introduced":"70ee6c20ad97e02c2b8098aeea96fefbbc3ac5c2"},{"fixed":"40298a988fca728ddc47316938da61e0f768c872"},{"introduced":"d26068059e83fe40de3430a512471d194119bee0"},{"fixed":"ce51bfac759dedac1537f4d5666dcd33fbc4a281"}],"database_specific":{"versions":[{"introduced":"8.1.0"},{"fixed":"8.1.29"},{"introduced":"8.2.0"},{"fixed":"8.2.20"},{"introduced":"8.3.0"},{"fixed":"8.3.8"}]}}],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"39"}]},{"events":[{"introduced":"0"},{"last_affected":"40"}]}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-4577.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
