|---|---|---|---|---|---|
| CVE-2017-9789 | 1 Apache | 1 Http Server | 2021-06-06 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2017-9798 | 2 Apache, Debian | 2 Http Server, Debian Linux | 2021-06-06 | 5.0 MEDIUM | 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-2018-11763 | 5 Apache, Canonical, Netapp and 2 more | 9 Http Server, Ubuntu Linux, Storage Automation Store and 6 more | 2021-06-06 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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-2018-1283 | 5 Apache, Canonical, Debian and 2 more | 8 Http Server, Ubuntu Linux, Debian Linux and 5 more | 2021-06-06 | 3.5 LOW | 5.3 MEDIUM |
| 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-2018-1302 | 3 Apache, Canonical, Netapp | 6 Http Server, Ubuntu Linux, Clustered Data Ontap and 3 more | 2021-06-06 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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 | 8 Http Server, Ubuntu Linux, Debian Linux and 5 more | 2021-06-06 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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-2018-1303 | 4 Apache, Canonical, Debian and 1 more | 7 Http Server, Ubuntu Linux, Debian Linux and 4 more | 2021-06-06 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2018-1333 | 4 Apache, Canonical, Netapp and 1 more | 6 Http Server, Ubuntu Linux, Cloud Backup and 3 more | 2021-06-06 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2018-17199 | 5 Apache, Canonical, Debian and 2 more | 6 Http Server, Ubuntu Linux, Debian Linux and 3 more | 2021-06-06 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2018-8011 | 2 Apache, Netapp | 2 Http Server, Cloud Backup | 2021-06-06 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2019-0196 | 3 Apache, Canonical, Debian | 3 Http Server, Ubuntu Linux, Debian Linux | 2021-06-06 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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-2019-0211 | 5 Apache, Canonical, Debian and 2 more | 5 Http Server, Ubuntu Linux, Debian Linux and 2 more | 2021-06-06 | 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-2019-0215 | 2 Apache, Fedoraproject | 2 Http Server, Fedora | 2021-06-06 | 6.0 MEDIUM | 7.5 HIGH |
| 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-2019-0217 | 8 Apache, Canonical, Debian and 5 more | 14 Http Server, Ubuntu Linux, Debian Linux and 11 more | 2021-06-06 | 6.0 MEDIUM | 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-2019-10081 | 2 Apache, Debian | 2 Http Server, Debian Linux | 2021-06-06 | 5.0 MEDIUM | 7.5 HIGH |
| HTTP/2 (2.4.20 through 2.4.39) very early pushes, for example configured with "H2PushResource", could lead to an overwrite of memory in the pushing request's pool, leading to crashes. The memory copied is that of the configured push link header values, not data supplied by the client. | |||||
| CVE-2020-11984 | 7 Apache, Canonical, Debian and 4 more | 13 Http Server, Ubuntu Linux, Debian Linux and 10 more | 2021-06-06 | 7.5 HIGH | 9.8 CRITICAL |
| Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE | |||||
| CVE-2020-11985 | 1 Apache | 1 Http Server | 2021-06-06 | 4.3 MEDIUM | 5.3 MEDIUM |
| IP address spoofing when proxying using mod_remoteip and mod_rewrite For configurations using proxying with mod_remoteip and certain mod_rewrite rules, an attacker could spoof their IP address for logging and PHP scripts. Note this issue was fixed in Apache HTTP Server 2.4.24 but was retrospectively allocated a low severity CVE in 2020. | |||||
| CVE-2020-11993 | 7 Apache, Canonical, Debian and 4 more | 13 Http Server, Ubuntu Linux, Debian Linux and 10 more | 2021-06-06 | 4.3 MEDIUM | 7.5 HIGH |
| Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers. | |||||
| CVE-2004-0113 | 1 Apache | 1 Http Server | 2021-06-06 | 5.0 MEDIUM | N/A |
| Memory leak in ssl_engine_io.c for mod_ssl in Apache 2 before 2.0.49 allows remote attackers to cause a denial of service (memory consumption) via plain HTTP requests to the SSL port of an SSL-enabled server. | |||||
| CVE-2003-0993 | 1 Apache | 1 Http Server | 2021-06-06 | 7.5 HIGH | N/A |
| mod_access in Apache 1.3 before 1.3.30, when running big-endian 64-bit platforms, does not properly parse Allow/Deny rules using IP addresses without a netmask, which could allow remote attackers to bypass intended access restrictions. | |||||
