CVE-2019-0211 8 Apache, Canonical, Debian and 5 more 28 Http Server, Ubuntu Linux, Debian Linux and 25 more 2025-07-28 7.8 High
In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected.
CVE-2021-40438 11 Apache, Broadcom, Debian and 8 more 45 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 42 more 2025-07-28 9 Critical
A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier.
CVE-2021-4034 7 Canonical, Oracle, Polkit Project and 4 more 37 Ubuntu Linux, Http Server, Zfs Storage Appliance Kit and 34 more 2025-07-28 7.8 High
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine.
CVE-2010-0425 5 Apache, Broadcom, Ibm and 2 more 6 Http Server, Vmware Ace Management Server, Http Server and 3 more 2025-07-24 N/A
modules/arch/win32/mod_isapi.c in mod_isapi in the Apache HTTP Server 2.0.37 through 2.0.63, 2.2.0 through 2.2.14, and 2.3.x before 2.3.7, when running on Windows, does not ensure that request processing is complete before calling isapi_unload for an ISAPI .dll module, which allows remote attackers to execute arbitrary code via unspecified vectors related to a crafted request, a reset packet, and "orphaned callback pointers."
CVE-2019-10219 3 Netapp, Oracle, Redhat 199 Active Iq Unified Manager, Element, Management Services For Element Software And Netapp Hci and 196 more 2025-07-07 6.1 Medium
A vulnerability was found in Hibernate-Validator. The SafeHtml validator annotation fails to properly sanitize payloads consisting of potentially malicious code in HTML comments and instructions. This vulnerability can result in an XSS attack.
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-2022-25313 6 Debian, Fedoraproject, Libexpat Project and 3 more 8 Debian Linux, Fedora, Libexpat and 5 more 2025-05-30 6.5 Medium
In Expat (aka libexpat) before 2.4.5, an attacker can trigger stack exhaustion in build_model via a large nesting depth in the DTD element.
CVE-2018-20843 8 Canonical, Debian, Fedoraproject and 5 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2025-05-30 7.5 High
In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks).
CVE-2022-25315 6 Debian, Fedoraproject, Libexpat Project and 3 more 12 Debian Linux, Fedora, Libexpat and 9 more 2025-05-05 9.8 Critical
In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames.
CVE-2022-25314 6 Debian, Fedoraproject, Libexpat Project and 3 more 8 Debian Linux, Fedora, Libexpat and 5 more 2025-05-05 7.5 High
In Expat (aka libexpat) before 2.4.5, there is an integer overflow in copyString.
CVE-2022-25236 5 Debian, Libexpat Project, Oracle and 2 more 11 Debian Linux, Libexpat, Http Server and 8 more 2025-05-05 9.8 Critical
xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters into namespace URIs.
CVE-2022-25235 6 Debian, Fedoraproject, Libexpat Project and 3 more 12 Debian Linux, Fedora, Libexpat and 9 more 2025-05-05 9.8 Critical
xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks for whether a UTF-8 character is valid in a certain context.
CVE-2021-36160 7 Apache, Broadcom, Debian and 4 more 16 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 13 more 2025-05-01 7.5 High
A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive).
CVE-2021-39275 7 Apache, Debian, Fedoraproject and 4 more 14 Http Server, Debian Linux, Fedora and 11 more 2025-05-01 9.8 Critical
ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache HTTP Server 2.4.48 and earlier.
CVE-2021-44790 8 Apache, Apple, Debian and 5 more 20 Http Server, Mac Os X, Macos and 17 more 2025-05-01 9.8 Critical
A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier.
CVE-2022-23943 5 Apache, Debian, Fedoraproject and 2 more 8 Http Server, Debian Linux, Fedora and 5 more 2025-05-01 9.8 Critical
Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and prior versions.
CVE-2022-21716 5 Debian, Fedoraproject, Oracle and 2 more 6 Debian Linux, Fedora, Http Server and 3 more 2025-04-22 7.5 High
Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 22.2.0, Twisted SSH client and server implement is able to accept an infinite amount of data for the peer's SSH version identifier. This ends up with a buffer using all the available memory. The attach is a simple as `nc -rv localhost 22 < /dev/zero`. A patch is available in version 22.2.0. There are currently no known workarounds.
CVE-2013-5704 5 Apache, Apple, Canonical and 2 more 17 Http Server, Mac Os X, Mac Os X Server and 14 more 2025-04-12 N/A
The mod_headers module in the Apache HTTP Server 2.2.22 allows remote attackers to bypass "RequestHeader unset" directives by placing a header in the trailer portion of data sent with chunked transfer coding. NOTE: the vendor states "this is not a security issue in httpd as such."
CVE-2014-0098 4 Apache, Canonical, Oracle and 1 more 7 Http Server, Ubuntu Linux, Http Server and 4 more 2025-04-12 N/A
The log_cookie function in mod_log_config.c in the mod_log_config module in the Apache HTTP Server before 2.4.8 allows remote attackers to cause a denial of service (segmentation fault and daemon crash) via a crafted cookie that is not properly handled during truncation.
CVE-2014-0226 4 Apache, Debian, Oracle and 1 more 9 Http Server, Debian Linux, Enterprise Manager Ops Center and 6 more 2025-04-12 N/A
Race condition in the mod_status module in the Apache HTTP Server before 2.4.10 allows remote attackers to cause a denial of service (heap-based buffer overflow), or possibly obtain sensitive credential information or execute arbitrary code, via a crafted request that triggers improper scoreboard handling within the status_handler function in modules/generators/mod_status.c and the lua_ap_scoreboard_worker function in modules/lua/lua_request.c.
