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. 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. The HTTP strict parsing changes added in 2.2.32 and 2.4.24 introduced a bug in token list parsing, which allows ap_find_token() to search past the end of its input string. Any bare CR present in request lines was treated as whitespace and remained in the request field member "the_request", while a bare CR in the request header field name would be honored as whitespace, and a bare CR in the request header field value was retained the input headers array. By specially crafting HTTP requests, the mod_md challenge handler would dereference a NULL pointer and cause the child process to segfault. /usr/local/, # ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_v2_module, https://ximenjianxue.blog.csdn.net, https://blog.csdn.net/weixin_42689212/article/details/119121188, : https://www.nginx.com/blog/updating-nginx-dns-resolver-vulnerability-cve-2021-23017/.

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. This requires a specially crafted request. 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.

Google introduces WebThe vulnerability is caused by a buffer over-read bug in the OpenSSL software, rather than a defect in the SSL or TLS protocol specification. In the more likely case, this memory is already reserved for future use and the issue has no effect at all. 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. API users should use the new ap_some_authn_required API added in 2.4.16 instead. |
in Apache HTTP Server versions 2.4.0 to 2.4.41, mod_proxy_ftp use of uninitialized value with malicious FTP backend. 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. Vulnerabilities. CISA's BOD 22-01 and Known Exploited Vulnerabilities Catalog for further guidance and requirements. 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. When under stress, closing many connections, the HTTP/2 handling code would sometimes access memory after it has been freed, resulting in potentially erratic behaviour. This allowed an attacker to inject unlimited request headers into the server, leading to eventual memory exhaustion. Acknowledgements: We would like to thank Vasileios Panopoulos and AdNovum Informatik AG for reporting this issue. Note that relaxing the behavior to 'Unsafe' will still not permit raw CTLs other than HTAB (where permitted), but will allow other RFC requirements to not be enforced, such as exactly two SP characters in the request line. A flaw was found in the WinNT MPM in httpd versions 2.4.1 to 2.4.9, when using the default AcceptFilter for that platform. Are we missing a CPE here?

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. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. 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. , : Acknowledgements: This issue was reported by Martin Holst Swende. not necessarily endorse the views expressed, or concur with

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. An authentication tag (SipHash MAC) is now added to prevent such attacks. We examine a new Spectre vulnerability in Linux, a handful of high-severity flaws affecting OpenSSL, still more problems surfacing with SolarWinds code, an intriguing new offering from our friends at Cloudflare, and the encouraging recognition of the need for increasing vigilance of the security of increasingly prevalent networked APIs. This could lead to an information disclosure due to a response mixup between users. Apache HTTP Server 2.4.53 and earlier on Windows may read beyond bounds when configured to process requests with the mod_isapi module. A malicious HTTP server could cause a crash in a caching forward proxy configuration. Acknowledgements: The Apache HTTP Server project would like to thank Ronald Crane (Zippenhop LLC) for reporting this issue. (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.). Readme Stars. 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. Acknowledgements: The issue was discovered by Simon Kappel. The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.48 and earlier. Science.gov

IBM Trust Center. Using fuzzed network input, the http/2 request handling could be made to access freed memory in string comparision when determining the method of a request and thus process the request incorrectly. A flaw was found in mod_proxy in httpd versions 2.4.6 to 2.4.9. Apache HTTP Server versions 2.4.6 to 2.4.46 mod_proxy_wstunnel configured on an URL that is not necessarily Upgraded by the origin server was tunneling the whole connection regardless, thus allowing for subsequent requests on the same connection to pass through with no HTTP validation, authentication or authorization possibly configured. |

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. No
No packages published . 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. Further, NIST does not
Actions. Packages 0. 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. XML parsing code in mod_dav incorrectly calculates the end of the string when removing leading spaces and places a NUL character outside the buffer, causing random crashes. 3.1 Official websites use .gov
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. JSON syntax hack allowed SQLi payloads to sneak past WAFs, Go SAML library vulnerable to authentication bypass, Tailscale VPN nodes vulnerable to DNS rebinding, RCE, Intel disputes seriousness of Data Centre Manager authentication flaw. X.509 fue publicado oficialmente en 1988 a partir de la norma X.500, [2] y asume un sistema jerrquico estricto de autoridades certificadoras (ACs) encargadas de emitir certificados.

We made improvements to the F5 (Build + Deploy) speed for Universal Windows Platform Our services are intended for corporate subscribers and you warrant OpenSSL 3.0.0 to 3.0.6 decodes some punycode email addresses in X.509 certificates improperly : 2021 9 14 . 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. Topping the list of this month's patches is CVE-2022-41033 (CVSS score: 7.8), a privilege escalation vulnerability in Windows COM+ Event System Service. FOIA

Acknowledgements: We would like to thank Javier Jimnez (
[email protected]) for reporting this issue. Acknowledgements: This issue was reported by Giancarlo Pellegrino and Davide Balzarotti. For configurations enabling support for HTTP/2, SSL client certificate validation was not enforced if configured, allowing clients unauthorized access to protected resources over HTTP/2. By maliciously crafting a sequence of request headers, an attacker may be able to cause a segmentation fault, or to force ap_find_token() to return an incorrect value. |

WebLoad balancing refers to efficiently distributing incoming network traffic across a group of backend servers, also known as a server farm or server pool.. Modern hightraffic websites must serve hundreds of thousands, if not millions, of concurrent requests from users or clients and return the correct text, images, video, or application data, all in a fast and Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. IBM Z Enterprise Security. 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 supporting Post-Handshake Authentication to bypass configured access control restrictions. This only affect a server that has enabled the h2 protocol.
