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. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.

A carefully crafted If: request header can cause a memory read, or write of a single zero byte, in a pool (heap) memory location beyond the header value sent. This could cause the process to crash. This issue affects Apache HTTP Server 2.4.54 and earlier.

A vulnerability was found in agy pontifex.http. It has been declared as critical. This vulnerability affects unknown code of the file lib/Http.coffee. The manipulation leads to sql injection. Upgrading to version 0.1.0 is able to address this issue. The name of the patch is e52a758f96861dcef2dabfecb9da191bb2e07761. It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-218356.

Http4s is a Scala interface for HTTP services. Starting with version 0.1.0 and prior to versions 0.21.34, 0.22.15, 0.23.17, and 1.0.0-M38, the `User-Agent` and `Server` header parsers are susceptible to a fatal error on certain inputs. In http4s, modeled headers are lazily parsed, so this only applies to services that explicitly request these typed headers. Fixes are released in 0.21.34, 0.22.15, 0.23.17, and 1.0.0-M38. As a workaround, use the weakly typed header interface.

A vulnerability was found in RamseyK httpserver. It has been rated as critical. This issue affects the function ResourceHost::getResource of the file src/ResourceHost.cpp of the component URI Handler. The manipulation of the argument uri leads to path traversal: '../filedir'. The attack may be initiated remotely. The name of the patch is 1a0de56e4dafff9c2f9c8f6b130a764f7a50df52. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-216863.

A vulnerability classified as critical was found in SimbCo httpster. This vulnerability affects the function fs.realpathSync of the file src/server.coffee. The manipulation leads to path traversal. The exploit has been disclosed to the public and may be used. The name of the patch is d3055b3e30b40b65d30c5a06d6e053dffa7f35d0. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-216748.

An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.

The llhttp parser in the http module in Node v18.7.0 does not correctly handle header fields that are not terminated with CLRF. This may result in HTTP Request Smuggling.

Proxmox Virtual Environment (PVE) and Proxmox Mail Gateway (PMG) are vulnerable to SSRF when proxying HTTP requests between pve(pmg)proxy and pve(pmg)daemon. An attacker with an unprivileged account can craft an HTTP request to achieve SSRF and file disclosure of any files on the server. Also, in Proxmox Mail Gateway, privilege escalation to the root@pam account is possible if the backup feature has ever been used, because backup files such as pmg-backup_YYYY_MM_DD_*.tgz have 0644 permissions and contain an authkey value. This is fixed in pve-http-server 4.1-3.

A response-header CRLF injection vulnerability in the Proxmox Virtual Environment (PVE) and Proxmox Mail Gateway (PMG) web interface allows a remote attacker to set cookies for a victim's browser that are longer than the server expects, causing a client-side DoS. This affects Chromium-based browsers because they allow injection of response headers with %0d. This is fixed in pve-http-server 4.1-3.
