A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.33, due to an out of bound access after a size limit is reached by reading the HTTP header. Git for Windows is now updated to version 2.35.1.2, which addresses this issue. sites that are more appropriate for your purpose. Connections could still be opened, but no streams where processed for these. An anonymous researcher has been credited with reporting the issue. To permit other .htaccess directives while denying the directive, see the AllowOverrideList directive. Readme Stars. If Apache HTTP Server 2.4.53 is configured to do transformations with mod_sed in contexts where the input to mod_sed may be very large, mod_sed may make excessively large memory allocations and trigger an abort.

A lock () or https:// means you've safely connected to the .gov website. A possible mitigation is to not enable the h2 protocol. Listed software is paired with specific information regarding which version contains the security fixes and which software still requires fixes. Note this issue was fixed in Apache HTTP Server 2.4.24 but was retrospectively allocated a low severity CVE in 2020. | The initial GA release, Apache httpd 2.4.1, includes fixes for all vulnerabilities which have been resolved in Apache httpd 2.2.22 and all older releases. For issues, let us know through the Report a Problem option in the upper right-hand corner of either the installer or the Visual Studio IDE itself. | While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing. Acknowledgements: This issue was reported by Ben Reser. This only affect a server that has enabled the h2 protocol. ap_escape_quotes() may write beyond the end of a buffer when given malicious input. https://nvd.nist.gov. The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the "POODLE" issue. Overview. Acknowledgements: We would like to thank Robert Święcki for reporting this issue. By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. 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'). This may be used to bypass IP based authentication on the origin server/application. Acknowledgements: The issue was discovered by Michael Kaufmann. By selecting these links, you will be leaving NIST webspace. This site requires JavaScript to be enabled for complete site functionality. Users are encouraged to migrate to 2.4.28 or later for this and other fixes. Acknowledgements: This issue was reported by Teguh P. Alko. We made improvements to the F5 (Build + Deploy) speed for Universal Windows Platform WebWeb vulnerability scanner Burp Suite Editions Release Notes. The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack. 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. Fix handling of the Require line in mod_lau when a LuaAuthzProvider is used in multiple Require directives with different arguments. Depending on h2 worker dimensioning, it was possible to block those with relatively few connections. ?. The keyword search will perform searching across all components of the CPE name for the user specified search text. A bug exists in the way mod_ssl handled client renegotiations. A maliciously constructed HTTP/2 request could cause mod_http2 to dereference a NULL pointer and crash the server process. Copyrights Acknowledgements: The issue was discovered by Jonathan Looney of Netflix. WebThe vulnerability was disclosed in 2002, but is still present in modern implementation due to poor configuration of the service. This rejection response was not fully initialised in the HTTP/2 protocol handler if the offending header was the very first one received or appeared in a a footer. The modules mod_proxy_ajp and mod_proxy_http did not always close the connection to the back end server when necessary as part of error handling. Company. Possible XSS for sites which use mod_negotiation and allow untrusted uploads to locations which have MultiViews enabled. 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. An authentication tag (SipHash MAC) is now added to prevent such attacks. This affects only HTTP/2 connections. 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. Original release date: November 07, 2022 f5 -- njs: Nginx NJS v0.7.2 was discovered to contain a heap-use-after-free bug caused by illegal memory copy in the function njs_json_parse_iterator_call at njs_json.c. Further, NIST does not The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug. Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. Vulnerability Disclosure This issue only affects Apache 2.4.49 and not earlier versions. WebA remote code vulnerability in F5 BIG-IP network appliances is now being scanned for by threat actors, and some experts have observed exploitation in the wild. FOIA This is a potential security issue, you are being redirected to may have information that would be of interest to you. 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. An out-of-bounds memory read was found in mod_proxy_fcgi. No IBM Cloud. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow, Acknowledgements: This issue was discovered and reported by GHSL team member @antonio-morales (Antonio Morales), Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Cookie header handled by mod_session can cause a NULL pointer dereference and crash, leading to a possible Denial Of Service, Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted SessionHeader sent by an origin server could cause a heap overflow, Acknowledgements: Discovered internally Christophe Jaillet, Apache HTTP Server versions 2.4.39 to 2.4.46 Unexpected matching behavior with 'MergeSlashes OFF', Acknowledgements: Discovered by Christoph Anton Mitterer. NIST does Please address comments about this page to nvd@nist.gov. Scientific Integrity Customers. | Each vulnerability is given a security impact rating by the Apache security team - please note that this rating may well vary from platform to platform. Acknowledgements: Reported by James Kettle of PortSwigger. 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. In September 2014, a variant of Daniel Bleichenbacher's PKCS#1 v1.5 RSA Signature Forgery vulnerability was announced by Intel Security Advanced Threat Research. Share sensitive information only on official, secure websites. Note: This is not assigned an httpd severity, as it is a defect in other software which overloaded well-established CGI environment variables, and does not reflect an error in HTTP server software. A resource consumption flaw was found in mod_deflate. Information Quality Standards | Using fuzzed network input, the http/2 session handling could be made to read memory after being freed, during connection shutdown. Copyright 1997-2022 The Apache Software Foundation. Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. Share sensitive information only on official, secure websites. Acknowledgements: The issue was discovered by Gal Goldshtein of F5 Networks. Google introduces may have information that would be of interest to you. Modules which call the legacy ap_get_basic_auth_pw() during the authentication phase MUST either immediately authenticate the user after the call, or else stop the request immediately with an error response, to avoid incorrectly authenticating the current request. 656 stars Watchers. inferences should be drawn on account of other sites being Acknowledgements: Anonymous working with Trend Micro Zero Day Initiative. WebFixed in Apache HTTP Server 2.4.52 moderate: Possible NULL dereference or SSRF in forward proxy configurations in Apache HTTP Server 2.4.51 and earlier (CVE-2021-44224) 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 the facts presented on these sites. the facts presented on these sites. HTTP/2 very early pushes, for example configured with "H2PushResource", could lead to an overwrite of memory in the pushing request's pool, leading to crashes. these sites. A malicious FastCGI server could send a carefully crafted response which could lead to a crash when reading past the end of a heap memory or stack buffer. An attacker could cause the link on the error page to be malfomed and instead point to a page of their choice. Actions. Please let us know. Note however this issue did not affect them directly and their output was already escaped to prevent cross-site scripting attacks. Detects whether a server is vulnerable to the F5 Ticketbleed bug (CVE-2016-9244). By selecting these links, you will be leaving NIST webspace. In particular the API is documented to answering if the request required authentication but only answers if there are Require lines in the applicable configuration. Acknowledgements: The issue was discovered by the Apache HTTP security team. A malicious client could perform a DoS attack by flooding a connection with requests and basically never reading responses on the TCP connection. inferences should be drawn on account of other sites being This crash would only be a denial of service if using a threaded MPM. Related Links. This led to a NULL pointer dereference on initialised memory, crashing reliably the child process. Environmental Policy Please note that if a vulnerability is shown below as being fixed in a "-dev" release then this means that a fix has been applied to the development source tree and will be part of an upcoming full release. In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. Acknowledgements: This issue was reported by Rainer M Canavan, A NULL pointer dereference was found in mod_cache. mod_mime can read one byte past the end of a buffer when sending a malicious Content-Type response header. 2.1 Acknowledgements: The issue was discovered by Yukitsugu Sasaki. | In each case where one agent accepts such CTL characters and does not treat them as whitespace, there is the possiblity in a proxy chain of generating two responses from a server behind the uncautious proxy agent. A remote attacker could send a specific truncated cookie causing a crash. A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead to request splitting or cache poisoning. CRLF Online, per e-mail of telefoon. Authentication is not required to exploit this vulnerability. Commerce.gov endorse any commercial products that may be mentioned on mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port. We also list the versions the flaw is known to affect, and where a flaw has not been verified list the version with a question mark. A crash in ErrorDocument handling was found. This site requires JavaScript to be enabled for complete site functionality. 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. 2.2 | Accessibility Select the basic search type to search modules on the active validation list.

The memory pools maintained by the server make this vulnerabilty 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. Prototype pollution project yields another Parse Server RCE, AppSec engineer keynote says Log4j revealed lessons were not learned from the Equifax breach, A rough guide to launching a career in cybersecurity. Acknowledgements: The Apache HTTP Server security team would like to thank Alex Nichols and Jakob Hirsch for reporting this issue. While no code distributed with the server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may hypothetically be affected. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. Acknowledgements: The issue was discovered by Diego Angulo from ImExHS. By toggling from 'Strict' behavior to 'Unsafe' behavior, some of the restrictions may be relaxed to allow some invalid HTTP/1.1 clients to communicate with the server, but this will reintroduce the possibility of the problems described in this assessment. Acknowledgements: We would like to thank individuals at the RedTeam Pentesting GmbH for reporting this issue. This issue affects Apache HTTP Server 2.4 version 2.4.52 and prior versions.
