Описание
When parsing HTTP/1.x header values, Envoy 1.9.0 and before does not reject embedded zero characters (NUL, ASCII 0x0). This allows remote attackers crafting header values containing embedded NUL characters to potentially bypass header matching rules, gaining access to unauthorized resources.
A flaw was found in Envoy version 1.9.0 and older, where Envoy does not reject embedded zero characters (NUL, ASCII 0x0) when processing HTTP/1.x header values. This flaw allows remote attackers crafting header values containing embedded NUL characters to potentially bypass header matching rules, gaining access to unauthorized resources.
