| CVE-2009-1903 | 2 Fedoraproject, Trustwave | 2 Fedora, Modsecurity | 2026-04-23 | N/A |
| The PDF XSS protection feature in ModSecurity before 2.5.8 allows remote attackers to cause a denial of service (Apache httpd crash) via a request for a PDF file that does not use the GET method. | ||||
| CVE-2009-1902 | 2 Fedoraproject, Trustwave | 2 Fedora, Modsecurity | 2026-04-23 | N/A |
| The multipart processor in ModSecurity before 2.5.9 allows remote attackers to cause a denial of service (crash) via a multipart form datapost request with a missing part header name, which triggers a NULL pointer dereference. | ||||
| CVE-2021-42717 | 5 Debian, F5, Oracle and 2 more | 6 Debian Linux, Nginx Modsecurity Waf, Http Server and 3 more | 2025-07-03 | 7.5 High |
| ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests. Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly vulnerable: the affected versions include 2.8.0 through 2.9.4. | ||||
| CVE-2022-48279 | 4 Debian, Owasp, Redhat and 1 more | 4 Debian Linux, Modsecurity, Jboss Core Services and 1 more | 2025-07-03 | 7.5 High |
| In ModSecurity before 2.9.6 and 3.x before 3.0.8, HTTP multipart requests were incorrectly parsed and could bypass the Web Application Firewall. NOTE: this is related to CVE-2022-39956 but can be considered independent changes to the ModSecurity (C language) codebase. | ||||
| CVE-2013-5705 | 2 Debian, Trustwave | 2 Debian Linux, Modsecurity | 2025-04-12 | N/A |
| apache2/modsecurity.c in ModSecurity before 2.7.6 allows remote attackers to bypass rules by using chunked transfer coding with a capitalized Chunked value in the Transfer-Encoding HTTP header. | ||||
| CVE-2013-1915 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Opensuse and 1 more | 2025-04-11 | N/A |
| ModSecurity before 2.7.3 allows remote attackers to read arbitrary files, send HTTP requests to intranet servers, or cause a denial of service (CPU and memory consumption) via an XML external entity declaration in conjunction with an entity reference, aka an XML External Entity (XXE) vulnerability. | ||||
| CVE-2009-5031 | 2 Opensuse, Trustwave | 2 Opensuse, Modsecurity | 2025-04-11 | N/A |
| ModSecurity before 2.5.11 treats request parameter values containing single quotes as files, which allows remote attackers to bypass filtering rules and perform other attacks such as cross-site scripting (XSS) attacks via a single quote in a request parameter in the Content-Disposition field of a request with a multipart/form-data Content-Type header. | ||||
| CVE-2012-2751 | 4 Debian, Opensuse, Oracle and 1 more | 4 Debian Linux, Opensuse, Http Server and 1 more | 2025-04-11 | N/A |
| ModSecurity before 2.6.6, when used with PHP, does not properly handle single quotes not at the beginning of a request parameter value in the Content-Disposition field of a request with a multipart/form-data Content-Type header, which allows remote attackers to bypass filtering rules and perform other attacks such as cross-site scripting (XSS) attacks. NOTE: this vulnerability exists because of an incomplete fix for CVE-2009-5031. | ||||
| CVE-2012-4528 | 3 Fedoraproject, Opensuse, Trustwave | 3 Fedora, Opensuse, Modsecurity | 2025-04-11 | N/A |
| The mod_security2 module before 2.7.0 for the Apache HTTP Server allows remote attackers to bypass rules, and deliver arbitrary POST data to a PHP application, via a multipart request in which an invalid part precedes the crafted data. | ||||
| CVE-2013-2765 | 3 Apache, Opensuse, Trustwave | 3 Http Server, Opensuse, Modsecurity | 2025-04-11 | N/A |
| The ModSecurity module before 2.7.4 for the Apache HTTP Server allows remote attackers to cause a denial of service (NULL pointer dereference, process crash, and disk consumption) via a POST request with a large body and a crafted Content-Type header. | ||||
| CVE-2023-24021 | 3 Debian, Redhat, Trustwave | 3 Debian Linux, Jboss Core Services, Modsecurity | 2025-04-02 | 7.5 High |
| Incorrect handling of '\0' bytes in file uploads in ModSecurity before 2.9.7 may allow for Web Application Firewall bypasses and buffer over-reads on the Web Application Firewall when executing rules that read the FILES_TMP_CONTENT collection. | ||||
