HTTP request smuggling is a type of attack that exploits the difference in interpretation of a set of HTTP header values between two devices.
With this type of request smuggling (“tunnel smuggling”?), you can send as many requests as you like via HTTP/2 multiplexing. Also, as we know from prior research, HTTP request smuggling enables a wide variety of attacks, including: forging internal headers, accessing restricted administrative...
We achieved critical impact for virtually every vulnerable host that we manually inspected. Introducing: TE.0 HTTP Request Smuggling One thing we know for sure is that HTTP Request Smuggling is still everywhere and massively under-researched. This has been suggested ...
Impact Advisory Description Somemod_proxy configurationson Apache HTTP Server versions2.4.0through2.4.55allow aHTTP 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 ...
WASC-27:HTTP Response Smuggling WASC-25:HTTP Response Splitting WASC-26:HTTP Request Smuggling WASC-24:HTTP Request Splitting 4. Affected software Any software that uses input data to construct headers is potentially vulnerable to this weakness. In most cases these are web applications, web servers...
DESCRIPTION:Apache HTTP Server is vulnerable to HTTP request smuggling, caused by the failure to close inbound connection when errors are encountered discarding the request body. An attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and co...
DESCRIPTION:Apache HTTP Server is vulnerable to HTTP request smuggling, caused by improper parsing of the HTTP transfer-encoding request header by the mod_proxy_uwsgi module. By sending a specially-crafted HTTP(S) transfer-encoding request header, an attacker could exploit this vulnerability to poiso...
Impact Prior topumaversion 5.5.0, usingpumawith a proxy which forwards LF characters as line endings could allow HTTP request smuggling. A client could smuggle a request through a proxy, causing the proxy to send a response back to another unknown client. ...
the vulnerability could be used totriggeran HTTP request smuggling attack. Also called HTTP resynchronization, this technique is a web application attack that tampers how a website processes sequences of HTTP requests received from more than one user. HTTP request smuggling also takes advant...
Complexity: The upgrade mechanism adds complexity to both client and server implementations, potentially introducing new bugs or security flaws, such as request smuggling. Potential for Confusion: Users may believe they're using a secure connection from the start when in reality, the initial request ...
