Design/Logic Flaw

An issue was discovered in Suricata before 6.0.4. It is possible to bypass/evade any HTTP-based signature by faking an RST TCP packet with random TCP options of the md5header from the client side. After the three-way handshake, it's possible to inject an RST ACK with a random TCP md5header option...

CVE-2017-16005

Http-signature is a "Reference implementation of Joyent's HTTP Signature Scheme". In versions =0.9.11, http-signature signs only the header values, but not the header names. This makes http-signature vulnerable to header forgery. Thus, if an attacker can intercept a request, he can swap header...

Header Forgery in http-signature

Affected versions of http-signature contain a vulnerability which can allow an attacker in a privileged network position to modify header names and change the meaning of the request, without requiring an updated signature. This problem occurs because vulnerable versions of http-signature sign the...
