CVE-2019-10097 | 2 Apache, Oracle | 8 Http Server, Communications Element Manager, Communications Session Report Manager and 5 more | 2024-02-28 | 6.0 MEDIUM | 7.2 HIGH |
In Apache HTTP Server 2.4.32-2.4.39, when mod_remoteip was configured to use a trusted intermediary proxy server using the "PROXY" protocol, a specially crafted PROXY header could trigger a stack buffer overflow or NULL pointer deference. This vulnerability could only be triggered by a trusted proxy and not by untrusted HTTP clients. | |||||
CVE-2019-10092 | 8 Apache, Canonical, Debian and 5 more | 10 Http Server, Ubuntu Linux, Debian Linux and 7 more | 2024-02-28 | 4.3 MEDIUM | 6.1 MEDIUM |
In Apache HTTP Server 2.4.0-2.4.39, a limited cross-site scripting issue was reported affecting the mod_proxy error page. An attacker could cause the link on the error page to be malformed and instead point to a page of their choice. This would only be exploitable where a server was set up with proxying enabled but was misconfigured in such a way that the Proxy Error page was displayed. | |||||
CVE-2019-0220 | 5 Apache, Canonical, Debian and 2 more | 5 Http Server, Ubuntu Linux, Debian Linux and 2 more | 2024-02-28 | 5.0 MEDIUM | 5.3 MEDIUM |
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-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 25 Http Server, Traffic Server, Mac Os X and 22 more | 2024-02-28 | 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-2019-0197 | 6 Apache, Canonical, Fedoraproject and 3 more | 12 Http Server, Ubuntu Linux, Fedora and 9 more | 2024-02-28 | 4.9 MEDIUM | 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-2019-0217 | 8 Apache, Canonical, Debian and 5 more | 14 Http Server, Ubuntu Linux, Debian Linux and 11 more | 2024-02-28 | 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-2019-0215 | 2 Apache, Fedoraproject | 2 Http Server, Fedora | 2024-02-28 | 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-2019-0196 | 3 Apache, Canonical, Debian | 3 Http Server, Ubuntu Linux, Debian Linux | 2024-02-28 | 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-2019-10081 | 2 Apache, Debian | 2 Http Server, Debian Linux | 2024-02-28 | 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-2019-0190 | 3 Apache, Openssl, Oracle | 6 Http Server, Openssl, Enterprise Manager Ops Center and 3 more | 2024-02-28 | 5.0 MEDIUM | 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 | 2024-02-28 | 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-2017-12171 | 2 Apache, Redhat | 5 Http Server, Enterprise Linux, Enterprise Linux Desktop and 2 more | 2024-02-28 | 6.4 MEDIUM | 6.5 MEDIUM |
A regression was found in the Red Hat Enterprise Linux 6.9 version of httpd 2.2.15-60, causing comments in the "Allow" and "Deny" configuration lines to be parsed incorrectly. A web administrator could unintentionally allow any client to access a restricted HTTP resource. | |||||
CVE-2016-4975 | 1 Apache | 1 Http Server | 2024-02-28 | 4.3 MEDIUM | 6.1 MEDIUM |
Possible CRLF injection allowing HTTP response splitting attacks for sites which use mod_userdir. This issue was mitigated by changes made in 2.4.25 and 2.2.32 which prohibit CR or LF injection into the "Location" or other outbound header key or value. Fixed in Apache HTTP Server 2.4.25 (Affected 2.4.1-2.4.23). Fixed in Apache HTTP Server 2.2.32 (Affected 2.2.0-2.2.31). | |||||
CVE-2018-17189 | 7 Apache, Canonical, Debian and 4 more | 13 Http Server, Ubuntu Linux, Debian Linux and 10 more | 2024-02-28 | 5.0 MEDIUM | 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 | 9 Http Server, Ubuntu Linux, Storage Automation Store and 6 more | 2024-02-28 | 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-2018-17199 | 5 Apache, Canonical, Debian and 2 more | 6 Http Server, Ubuntu Linux, Debian Linux and 3 more | 2024-02-28 | 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-2018-1302 | 3 Apache, Canonical, Netapp | 6 Http Server, Ubuntu Linux, Clustered Data Ontap and 3 more | 2024-02-28 | 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-2017-15710 | 5 Apache, Canonical, Debian and 2 more | 8 Http Server, Ubuntu Linux, Debian Linux and 5 more | 2024-02-28 | 5.0 MEDIUM | 7.5 HIGH |
In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the process would crash which could be used as a Denial of Service attack. In the more likely case, this memory is already reserved for future use and the issue has no effect at all. | |||||
CVE-2018-1333 | 4 Apache, Canonical, Netapp and 1 more | 6 Http Server, Ubuntu Linux, Cloud Backup and 3 more | 2024-02-28 | 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-2018-1303 | 4 Apache, Canonical, Debian and 1 more | 7 Http Server, Ubuntu Linux, Debian Linux and 4 more | 2024-02-28 | 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. |
