Undertow HTTP Request Line Parsing Vulnerability

CVE-2017-2666 · MEDIUM Severity

AV:N/AC:L/AU:N/C:P/I:P/A:N

It was discovered in Undertow that the code that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack, or obtain sensitive information from requests other than their own.
