| In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code. | |||||
| CVE-2016-5425 | 3 Apache, Oracle, Redhat | 9 Tomcat, Instantis Enterprisetrack, Linux and 6 more | 2025-04-12 | 7.2 HIGH | 7.8 HIGH |
| The Tomcat package on Red Hat Enterprise Linux (RHEL) 7, Fedora, CentOS, Oracle Linux, and possibly other Linux distributions uses weak permissions for /usr/lib/tmpfiles.d/tomcat.conf, which allows local users to gain root privileges by leveraging membership in the tomcat group. | |||||
| CVE-2019-0211 | 8 Apache, Canonical, Debian and 5 more | 27 Http Server, Ubuntu Linux, Debian Linux and 24 more | 2025-04-04 | 7.2 HIGH | 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-2020-1938 | 7 Apache, Blackberry, Debian and 4 more | 21 Geode, Tomcat, Good Control and 18 more | 2025-03-28 | 7.5 HIGH | 9.8 CRITICAL |
| When using the Apache JServ Protocol (AJP), care must be taken when trusting incoming connections to Apache Tomcat. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP connection. If such connections are available to an attacker, they can be exploited in ways that may be surprising. In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, Tomcat shipped with an AJP Connector enabled by default that listened on all configured IP addresses. It was expected (and recommended in the security guide) that this Connector would be disabled if not required. This vulnerability report identified a mechanism that allowed: - returning arbitrary files from anywhere in the web application - processing any file in the web application as a JSP Further, if the web application allowed file upload and stored those files within the web application (or the attacker was able to control the content of the web application by some other means) then this, along with the ability to process a file as a JSP, made remote code execution possible. It is important to note that mitigation is only required if an AJP port is accessible to untrusted users. Users wishing to take a defence-in-depth approach and block the vector that permits returning arbitrary files and execution as JSP may upgrade to Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. A number of changes were made to the default AJP Connector configuration in 9.0.31 to harden the default configuration. It is likely that users upgrading to 9.0.31, 8.5.51 or 7.0.100 or later will need to make small changes to their configurations. | |||||
| CVE-2021-41773 | 4 Apache, Fedoraproject, Netapp and 1 more | 4 Http Server, Fedora, Cloud Backup and 1 more | 2025-03-21 | 4.3 MEDIUM | 7.5 HIGH |
| A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue is known to be exploited in the wild. This issue only affects Apache 2.4.49 and not earlier versions. The fix in Apache HTTP Server 2.4.50 was found to be incomplete, see CVE-2021-42013. | |||||
| CVE-2021-42013 | 4 Apache, Fedoraproject, Netapp and 1 more | 6 Http Server, Fedora, Cloud Backup and 3 more | 2025-03-21 | 7.5 HIGH | 9.8 CRITICAL |
| It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue only affects Apache 2.4.49 and Apache 2.4.50 and not earlier versions. | |||||
| CVE-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 25 Http Server, Traffic Server, Mac Os X and 22 more | 2025-01-14 | 7.8 HIGH | 7.5 HIGH |
| Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. | |||||
| CVE-2021-45105 | 5 Apache, Debian, Netapp and 2 more | 121 Log4j, Debian Linux, Cloud Manager and 118 more | 2024-11-21 | 4.3 MEDIUM | 5.9 MEDIUM |
| Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1. | |||||
| CVE-2021-44224 | 6 Apache, Apple, Debian and 3 more | 12 Http Server, Mac Os X, Macos and 9 more | 2024-11-21 | 6.4 MEDIUM | 8.2 HIGH |
| A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). | |||||
| CVE-2021-41524 | 4 Apache, Fedoraproject, Netapp and 1 more | 4 Http Server, Fedora, Cloud Backup and 1 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing, allowing an external source to DoS the server. This requires a specially crafted request. The vulnerability was recently introduced in version 2.4.49. No exploit is known to the project. | |||||
| CVE-2021-34798 | 8 Apache, Broadcom, Debian and 5 more | 18 Http Server, Brocade Fabric Operating System Firmware, Debian Linux and 15 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier. | |||||
| CVE-2021-33503 | 3 Fedoraproject, Oracle, Python | 5 Fedora, Enterprise Manager Ops Center, Instantis Enterprisetrack and 2 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in urllib3 before 1.26.5. When provided with a URL containing many @ characters in the authority component, the authority regular expression exhibits catastrophic backtracking, causing a denial of service if a URL were passed as a parameter or redirected to via an HTTP redirect. | |||||
