CVE-2017-2666
Undertow-core vulnerable to HTTP Request Smuggling
Also known as GHSA-mcfm-h73v-635m
Published 8 y ago · modified 4 mo ago · JSON
Summary
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.
Exploit prediction (EPSS)
3.09% probability of exploitation in the next 30 days, higher than 88% of all scored CVEs.
