CVE-2024-1019 1 Trustwave 1 Modsecurity 2024-11-21 8.6 High
ModSecurity / libModSecurity 3.0.0 to 3.0.11 is affected by a WAF bypass for path-based payloads submitted via specially crafted request URLs. ModSecurity v3 decodes percent-encoded characters present in request URLs before it separates the URL path component from the optional query string component. This results in an impedance mismatch versus RFC compliant back-end applications. The vulnerability hides an attack payload in the path component of the URL from WAF rules inspecting it. A back-end may be vulnerable if it uses the path component of request URLs to construct queries. Integrators and users are advised to upgrade to 3.0.12. The ModSecurity v2 release line is not affected by this vulnerability.
CVE-2023-38285 1 Trustwave 1 Modsecurity 2024-11-21 7.5 High
Trustwave ModSecurity 3.x before 3.0.10 has Inefficient Algorithmic Complexity.
CVE-2023-28882 1 Trustwave 1 Modsecurity 2024-11-21 7.5 High
Trustwave ModSecurity 3.0.5 through 3.0.8 before 3.0.9 allows a denial of service (worker crash and unresponsiveness) because some inputs cause a segfault in the Transaction class for some configurations.
CVE-2023-24021 3 Debian, Redhat, Trustwave 3 Debian Linux, Jboss Core Services, Modsecurity 2024-11-21 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.
CVE-2022-48279 3 Debian, Redhat, Trustwave 3 Debian Linux, Jboss Core Services, Modsecurity 2024-11-21 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 4 Debian, F5, Oracle and 1 more 5 Debian Linux, Nginx Modsecurity Waf, Http Server and 2 more 2024-11-21 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-2020-15598 2 Debian, Trustwave 2 Debian Linux, Modsecurity 2024-11-21 7.5 High
Trustwave ModSecurity 3.x through 3.0.4 allows denial of service via a special request. NOTE: The discoverer reports "Trustwave has signaled they are disputing our claims." The CVE suggests that there is a security issue with how ModSecurity handles regular expressions that can result in a Denial of Service condition. The vendor does not consider this as a security issue because1) there is no default configuration issue here. An attacker would need to know that a rule using a potentially problematic regular expression was in place, 2) the attacker would need to know the basic nature of the regular expression itself to exploit any resource issues. It's well known that regular expression usage can be taxing on system resources regardless of the use case. It is up to the administrator to decide on when it is appropriate to trade resources for potential security benefit
CVE-2019-25043 1 Trustwave 1 Modsecurity 2024-11-21 5.3 Medium
ModSecurity 3.x before 3.0.4 mishandles key-value pair parsing, as demonstrated by a "string index out of range" error and worker-process crash for a "Cookie: =abc" header.
CVE-2019-19886 2 Fedoraproject, Trustwave 2 Fedora, Modsecurity 2024-11-21 7.5 High
Trustwave ModSecurity 3.0.0 through 3.0.3 allows an attacker to send crafted requests that may, when sent quickly in large volumes, lead to the server becoming slow or unresponsive (Denial of Service) because of a flaw in Transaction::addRequestHeader in transaction.cc.
CVE-2018-13065 1 Trustwave 1 Modsecurity 2024-11-21 N/A
ModSecurity 3.0.0 has XSS via an onerror attribute of an IMG element. NOTE: a third party has disputed this issue because it may only apply to environments without a Core Rule Set configured
CVE-2013-5705 2 Debian, Trustwave 2 Debian Linux, Modsecurity 2024-11-21 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-2013-2765 3 Apache, Opensuse, Trustwave 3 Http Server, Opensuse, Modsecurity 2024-11-21 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-2013-1915 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Opensuse and 1 more 2024-11-21 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 2024-11-21 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 2024-11-21 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-2009-5031 2 Opensuse, Trustwave 2 Opensuse, Modsecurity 2024-11-21 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-2009-1903 2 Fedoraproject, Trustwave 2 Fedora, Modsecurity 2024-11-21 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 2024-11-21 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.
