2018-07-03 | CVE-2018-13065 | 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 | Modsecurity | 6.1 | ||
2020-01-21 | CVE-2019-19886 | 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. | Fedora, Modsecurity | 7.5 | ||
2020-10-06 | CVE-2020-15598 | 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... | Debian_linux, Modsecurity | 7.5 | ||
2021-05-06 | CVE-2019-25043 | 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. | Modsecurity | 5.3 | ||
2021-12-07 | CVE-2021-42717 | 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. | Debian_linux, Nginx_modsecurity_waf, Http_server, Zfs_storage_appliance_kit, Modsecurity, Modsecurity | 7.5 | ||
2023-01-20 | CVE-2022-48279 | 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. | Debian_linux, Modsecurity, Modsecurity | 7.5 | ||
2023-04-28 | CVE-2023-28882 | 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. | Modsecurity | 7.5 | ||
2023-07-26 | CVE-2023-38285 | Trustwave ModSecurity 3.x before 3.0.10 has Inefficient Algorithmic Complexity. | Modsecurity | 7.5 | ||
2024-01-30 | CVE-2024-1019 | 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... | Modsecurity | 8.6 | ||
2025-06-02 | CVE-2025-48866 | ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. Versions prior to 2.9.10 contain a denial of service vulnerability similar to GHSA-859r-vvv8-rm8r/CVE-2025-47947. The `sanitiseArg` (and `sanitizeArg` - this is the same action but an alias) is vulnerable to adding an excessive number of arguments, thereby leading to denial of service. Version 2.9.10 fixes the issue. As a workaround, avoid using rules that contain the `sanitiseArg`... | Modsecurity | N/A |
