CVE-2022-48279 3 Debian, Owasp, Trustwave 3 Debian Linux, Modsecurity, Modsecurity 2025-07-03 N/A 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-2021-42717 5 Debian, F5, Oracle and 2 more 6 Debian Linux, Nginx Modsecurity Waf, Http Server and 3 more 2025-07-03 5.0 MEDIUM 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-2025-47947 1 Trustwave 1 Modsecurity 2025-06-20 N/A 7.5 HIGH
ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. Versions up to and including 2.9.8 are vulnerable to denial of service in one special case (in stable released versions): when the payload's content type is `application/json`, and there is at least one rule which does a `sanitiseMatchedBytes` action. A patch is available at pull request 3389 and expected to be part of version 2.9.9. No known workarounds are available.
CVE-2024-46292 1 Trustwave 1 Modsecurity 2025-06-17 N/A 7.5 HIGH
A buffer overflow in modsecurity v3.0.12 allows attackers to cause a Denial of Service (DoS) via a crafted input inserted into the name parameter. NOTE: this is disputed by the Supplier because it cannot be reproduced. Also, the product's documentation indicates that it is not guaranteed to be usable with very large values of SecRequestBodyNoFilesLimit (which are required by the claimed issue).
CVE-2013-5705 2 Debian, Trustwave 2 Debian Linux, Modsecurity 2025-04-12 5.0 MEDIUM 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-2009-5031 2 Opensuse, Trustwave 2 Opensuse, Modsecurity 2025-04-11 4.3 MEDIUM 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-2013-1915 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Opensuse and 1 more 2025-04-11 7.5 HIGH 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-2012-4528 3 Fedoraproject, Opensuse, Trustwave 3 Fedora, Opensuse, Modsecurity 2025-04-11 5.0 MEDIUM 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-2012-2751 4 Debian, Opensuse, Oracle and 1 more 4 Debian Linux, Opensuse, Http Server and 1 more 2025-04-11 4.3 MEDIUM 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-2013-2765 3 Apache, Opensuse, Trustwave 3 Http Server, Opensuse, Modsecurity 2025-04-11 5.0 MEDIUM 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-2009-1902 2 Fedoraproject, Trustwave 2 Fedora, Modsecurity 2025-04-09 5.0 MEDIUM 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-2009-1903 2 Fedoraproject, Trustwave 2 Fedora, Modsecurity 2025-04-09 4.3 MEDIUM 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-2023-24021 2 Debian, Trustwave 2 Debian Linux, Modsecurity 2025-04-02 N/A 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.
