Vulnerability from variot
An integer overflow exists in HAProxy 2.0 through 2.5 in htx_add_header that can be exploited to perform an HTTP request smuggling attack, allowing an attacker to bypass all configured http-request HAProxy ACLs and possibly other ACLs. HAProxy Exists in an integer overflow vulnerability.Information may be tampered with. HAProxy is an open source TCP/HTTP load balancing server from the French HAProxy= company. =
There is an input validation error vulnerability in HAProxy, which stems from the lack of header name length checking in the htx_add_header() and htx_add_trailer() functions in HAProxy, which can be exploited by attackers to cause request smuggling attacks or response splitting attacks. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256
