CVE-2019-0220 6 Apache, Canonical, Debian and 3 more 8 Http Server, Ubuntu Linux, Debian Linux and 5 more 2024-11-21 N/A
A vulnerability was found in Apache HTTP Server 2.4.0 to 2.4.38. When the path component of a request URL contains multiple consecutive slashes ('/'), directives such as LocationMatch and RewriteRule must account for duplicates in regular expressions while other aspects of the servers processing will implicitly collapse them.
CVE-2019-0217 8 Apache, Canonical, Debian and 5 more 16 Http Server, Ubuntu Linux, Debian Linux and 13 more 2024-11-21 7.5 High
In Apache HTTP Server 2.4 release 2.4.38 and prior, a race condition in mod_auth_digest when running in a threaded server could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions.
CVE-2019-0215 3 Apache, Fedoraproject, Redhat 3 Http Server, Fedora, Enterprise Linux 2024-11-21 N/A
In Apache HTTP Server 2.4 releases 2.4.37 and 2.4.38, a bug in mod_ssl when using per-location client certificate verification with TLSv1.3 allowed a client to bypass configured access control restrictions.
CVE-2019-0211 8 Apache, Canonical, Debian and 5 more 28 Http Server, Ubuntu Linux, Debian Linux and 25 more 2024-11-21 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-2019-0197 6 Apache, Canonical, Fedoraproject and 3 more 12 Http Server, Ubuntu Linux, Fedora and 9 more 2024-11-21 4.2 Medium
A vulnerability was found in Apache HTTP Server 2.4.34 to 2.4.38. When HTTP/2 was enabled for a http: host or H2Upgrade was enabled for h2 on a https: host, an Upgrade request from http/1.1 to http/2 that was not the first request on a connection could lead to a misconfiguration and crash. Server that never enabled the h2 protocol or that only enabled it for https: and did not set "H2Upgrade on" are unaffected by this issue.
CVE-2019-0196 4 Apache, Canonical, Debian and 1 more 5 Http Server, Ubuntu Linux, Debian Linux and 2 more 2024-11-21 N/A
A vulnerability was found in Apache HTTP Server 2.4.17 to 2.4.38. Using fuzzed network input, the http/2 request handling could be made to access freed memory in string comparison when determining the method of a request and thus process the request incorrectly.
CVE-2019-0190 3 Apache, Openssl, Oracle 6 Http Server, Openssl, Enterprise Manager Ops Center and 3 more 2024-11-21 7.5 High
A bug exists in the way mod_ssl handled client renegotiations. A remote attacker could send a carefully crafted request that would cause mod_ssl to enter a loop leading to a denial of service. This bug can be only triggered with Apache HTTP Server version 2.4.37 when using OpenSSL version 1.1.1 or later, due to an interaction in changes to handling of renegotiation attempts.
CVE-2018-8011 2 Apache, Netapp 2 Http Server, Cloud Backup 2024-11-21 N/A
By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. This could be used to DoS the server. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.33).
CVE-2018-1333 4 Apache, Canonical, Netapp and 1 more 7 Http Server, Ubuntu Linux, Cloud Backup and 4 more 2024-11-21 N/A
By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.18-2.4.30,2.4.33).
CVE-2018-1312 5 Apache, Canonical, Debian and 2 more 15 Http Server, Ubuntu Linux, Debian Linux and 12 more 2024-11-21 9.8 Critical
In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection.
CVE-2018-1303 5 Apache, Canonical, Debian and 2 more 10 Http Server, Ubuntu Linux, Debian Linux and 7 more 2024-11-21 N/A
A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.
CVE-2018-1302 4 Apache, Canonical, Netapp and 1 more 7 Http Server, Ubuntu Linux, Clustered Data Ontap and 4 more 2024-11-21 N/A
When an HTTP/2 stream was destroyed after being handled, the Apache HTTP Server prior to version 2.4.30 could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerability hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk.
CVE-2018-1301 5 Apache, Canonical, Debian and 2 more 10 Http Server, Ubuntu Linux, Debian Linux and 7 more 2024-11-21 N/A
A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.
CVE-2018-1283 5 Apache, Canonical, Debian and 2 more 10 Http Server, Ubuntu Linux, Debian Linux and 7 more 2024-11-21 N/A
In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a "Session" header. This comes from the "HTTP_SESSION" variable name used by mod_session to forward its data to CGIs, since the prefix "HTTP_" is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications.
CVE-2018-17199 6 Apache, Canonical, Debian and 3 more 9 Http Server, Ubuntu Linux, Debian Linux and 6 more 2024-11-21 N/A
In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded.
CVE-2018-17189 7 Apache, Canonical, Debian and 4 more 14 Http Server, Ubuntu Linux, Debian Linux and 11 more 2024-11-21 5.3 Medium
In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections.
CVE-2018-11763 5 Apache, Canonical, Netapp and 2 more 11 Http Server, Ubuntu Linux, Storage Automation Store and 8 more 2024-11-21 N/A
In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol.
CVE-2017-9798 3 Apache, Debian, Redhat 8 Http Server, Debian Linux, Enterprise Linux and 5 more 2024-11-21 7.5 High
Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c.
CVE-2017-9789 1 Apache 1 Http Server 2024-11-21 N/A
When under stress, closing many connections, the HTTP/2 handling code in Apache httpd 2.4.26 would sometimes access memory after it has been freed, resulting in potentially erratic behaviour.
CVE-2017-9788 6 Apache, Apple, Debian and 3 more 18 Http Server, Mac Os X, Debian Linux and 15 more 2024-11-21 N/A
In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service.
