It is awaiting reanalysis which may result in further changes to the information provided. | Acknowledgements: This issue was reported by Jeff Trawick of the ASF. Detects whether a server is vulnerable to the F5 Ticketbleed bug (CVE-2016-9244). Listed software is paired with specific information regarding which version contains the security fixes and which software still requires fixes. Secure .gov websites use HTTPS ,,, : Acknowledgements: The issue was discovered internally by the Apache HTTP Server team. No packages published . (Note that this vulnerability was fixed in the 2.4.7 release, but the security impact was not disclosed at the time of the release.). It was introduced into the software in 2012 and publicly disclosed in April 2014. Use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed. No packages published . There may be other web If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes.

This can be abused for a DoS on the server. This site requires JavaScript to be enabled for complete site functionality. 15.9.39 This page contains an overview of software (un)affected by the OpenSSL vulnerability. | The vulnerability was recently introduced in version 2.4.49. Insecure handling of LD_LIBRARY_PATH was found that could lead to the current working directory to be searched for DSOs. This issue affects Apache HTTP Server 2.4.51 and earlier. A stack recursion crash in the mod_lua module was found. 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. An attacker can leverage this vulnerability to execute code in the context of root. Denotes Vulnerable Software WebFind software and development products, explore tools and technologies, connect with other developers and more. This is a potential security issue, you are being redirected to A remote attacker could send a carefully crafted request to a server configured as a reverse proxy, and cause the child process to crash. Beyond Security is proud to be part of Fortras comprehensive cybersecurity portfolio. Company. these sites. A maliciously constructed HTTP/2 request could cause mod_http2 to dereference a NULL pointer and crash the server process. Since 2.4.x Require lines are used for authorization as well and can appear in configurations even when no authentication is required and the request is entirely unrestricted. Acknowledgements: The issue was discovered by Craig Young, . 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. When generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. 181 forks Releases No releases published. Information Quality Standards When evaluating the impact of this vulnerability to your organization, take into account the nature of the data that is being protected and act according to your organizations risk acceptance. This vulnerability has been modified and is currently undergoing reanalysis. By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. In 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. If ErrorDocument 400 was configured pointing to a local URL-path with the INCLUDES filter active, a NULL dereference would occur when handling the error, causing the child process to crash. A XSS flaw affected the mod_proxy_balancer manager interface. Malformed requests may cause the server to dereference a NULL pointer. | Official websites use .gov | 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. inferences should be drawn on account of other sites being By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. Acknowledgements: Apache HTTP server would like to thank LI ZHI XIN from NSFoucs for reporting this. Acknowledgements: This issue was reported by Matei "Mal" Badanoiu. The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with mod_luas r:puts() function.

F5 issues fixes for BIG-IP, BIG-IQ flaws discovered by Rapid7 Smartphone shipments in Europe down by 16% in 3Q 2022 Apple ignoring requests to resume pay deal talks, union claims No mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port. Vulnerability Disclosure This could lead to modules using this API to allow access when they should otherwise not do so. | A design error in the "ap_some_auth_required" function renders the API unusuable in httpd 2.4.x. CVSS V2 scoring evaluates the impact of the vulnerability on the host where the vulnerability is located. WebCurrent Description . Secure .gov websites use HTTPS This issue is known to be exploited in the wild. An attacker able to access a public server status page on a server using a threaded MPM could send a carefully crafted request which could lead to a heap buffer overflow. The use of request body decompression is not a common configuration. This could be used to DoS the server. Learn More In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. Acknowledgements: LI ZHI XIN from NSFocus Security Team. Acknowledgements: The Apache HTTP Server project would like to thank Gaetan Ferry (Synacktiv) for reporting this issue. An attacker can send crafted packets through vulnerable devices to cause Denial-of-service (DoS) or to perform a man-in-the-middle (MitM) attack against a target network. It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. A bug exists in the way mod_ssl handled client renegotiations. This behavior may be avoided by listing all unusual HTTP Methods in a global httpd.conf RegisterHttpMethod directive in httpd release 2.4.25 and later. Authentication is not required to exploit this vulnerability. A malicious client could force the server to misinterpret the request length, allowing cache poisoning or credential hijacking if an intermediary proxy is in use. FOIA | Please let us know.

The memory copied is that of the configured push link header values, not data supplied by the client. A lock () or https:// means you've safely connected to the .gov website. Select the advanced search type to to search modules on the historical and revoked module lists. In the more likely case, this memory is already reserved for future use and the issue has no effect at all. 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. These defects represent a security concern when httpd is participating in any chain of proxies or interacting with back-end application servers, either through mod_proxy or using conventional CGI mechanisms. We have taken this opportunity to also remove request data from many other in-built error messages.

WebHeartbleed was a security bug in the OpenSSL cryptography library, which is a widely used implementation of the Transport Layer Security (TLS) protocol. 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. Modules compiled and distributed separately from Apache HTTP Server that use the "ap_rputs" function and may pass it a very large (INT_MAX or larger) string must be compiled against current headers to resolve the issue. NIST does This crash would only be a denial of service if using a threaded MPM.
