CVE-2023-25725 2 Debian, Haproxy 2 Debian Linux, Haproxy 2025-03-20 N/A 9.1 CRITICAL
HAProxy before 2.7.3 may allow a bypass of access control because HTTP/1 headers are inadvertently lost in some situations, aka "request smuggling." The HTTP header parsers in HAProxy may accept empty header field names, which could be used to truncate the list of HTTP headers and thus make some headers disappear after being parsed and processed for HTTP/1.0 and HTTP/1.1. For HTTP/2 and HTTP/3, the impact is limited because the headers disappear before being parsed and processed, as if they had not been sent by the client. The fixed versions are 2.7.3, 2.6.9, 2.5.12, 2.4.22, 2.2.29, and 2.0.31.
CVE-2024-6827 2025-03-20 N/A 7.5 HIGH
Gunicorn version 21.2.0 does not properly validate the value of the 'Transfer-Encoding' header as specified in the RFC standards, which leads to the default fallback method of 'Content-Length,' making it vulnerable to TE.CL request smuggling. This vulnerability can lead to cache poisoning, data exposure, session manipulation, SSRF, XSS, DoS, data integrity compromise, security bypass, information leakage, and business logic abuse.
CVE-2024-56908 2025-03-17 N/A 6.8 MEDIUM
In Perfex Crm < 3.2.1, an authenticated attacker can send a crafted HTTP POST request to the affected upload_sales_file endpoint. By providing malicious input in the rel_id parameter, combined with improper input validation, the attacker can bypass restrictions and upload arbitrary files to directories of their choice, potentially leading to remote code execution or server compromise.
CVE-2023-48365 1 Qlik 1 Qlik Sense 2025-03-13 N/A 9.6 CRITICAL
Qlik Sense Enterprise for Windows before August 2023 Patch 2 allows unauthenticated remote code execution, aka QB-21683. Due to improper validation of HTTP headers, a remote attacker is able to elevate their privilege by tunneling HTTP requests, allowing them to execute HTTP requests on the backend server that hosts the repository application. The fixed versions are August 2023 Patch 2, May 2023 Patch 6, February 2023 Patch 10, November 2022 Patch 12, August 2022 Patch 14, May 2022 Patch 16, February 2022 Patch 15, and November 2021 Patch 17. NOTE: this issue exists because of an incomplete fix for CVE-2023-41265.
CVE-2022-22536 1 Sap 3 Content Server, Netweaver Application Server Abap, Web Dispatcher 2025-03-13 10.0 HIGH 10.0 CRITICAL
SAP NetWeaver Application Server ABAP, SAP NetWeaver Application Server Java, ABAP Platform, SAP Content Server 7.53 and SAP Web Dispatcher are vulnerable for request smuggling and request concatenation. An unauthenticated attacker can prepend a victim's request with arbitrary data. This way, the attacker can execute functions impersonating the victim or poison intermediary Web caches. A successful attack could result in complete compromise of Confidentiality, Integrity and Availability of the system.
CVE-2025-29904 2025-03-12 N/A 5.3 MEDIUM

CVE-2023-33934 1 Apache 1 Traffic Server 2025-02-13 N/A 9.1 CRITICAL
Improper Input Validation vulnerability in Apache Software Foundation Apache Traffic Server.This issue affects Apache Traffic Server: through 9.2.1.
CVE-2023-25690 1 Apache 1 Http Server 2025-02-13 N/A 9.8 CRITICAL
Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied request-target (URL) data and is then re-inserted into the proxied request-target using variable substitution. For example, something like: RewriteEngine on RewriteRule "^/here/(.*)" "http://example.com:8080/elsewhere?$1"; [P] ProxyPassReverse /here/ http://example.com:8080/ Request splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version 2.4.56 of Apache HTTP Server.
CVE-2023-25950 1 Haproxy 1 Haproxy 2025-02-11 N/A 7.3 HIGH
HTTP request/response smuggling vulnerability in HAProxy version 2.7.0, and 2.6.1 to 2.6.7 allows a remote attacker to alter a legitimate user's request. As a result, the attacker may obtain sensitive information or cause a denial-of-service (DoS) condition.

CVE-2022-24801 4 Debian, Fedoraproject, Oracle and 1 more 4 Debian Linux, Fedora, Zfs Storage Appliance Kit and 1 more 2024-11-25 6.8 MEDIUM 8.1 HIGH
Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to version 22.4.0rc1, the Twisted Web HTTP 1.1 server, located in the `twisted.web.http` module, parsed several HTTP request constructs more leniently than permitted by RFC 7230. This non-conformant parsing can lead to desync if requests pass through multiple HTTP parsers, potentially resulting in HTTP request smuggling. Users who may be affected use Twisted Web's HTTP 1.1 server and/or proxy and also pass requests through a different HTTP server and/or proxy. The Twisted Web client is not affected. The HTTP 2.0 server uses a different parser, so it is not affected. The issue has been addressed in Twisted 22.4.0rc1. Two workarounds are available: Ensure any vulnerabilities in upstream proxies have been addressed, such as by upgrading them; or filter malformed requests by other means, such as configuration of an upstream proxy.
CVE-2020-10108 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2024-11-25 7.5 HIGH 9.8 CRITICAL
In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request.
