NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat6-servlet-2.5-api package and not the tomcat6-servlet-2.5-api package as distributed by Oracle. See How to fix? for Oracle:6 relevant fixed versions and status.

The code in Apache Tomcat 9.0.0.M1 to 9.0.0.M11, 8.5.0 to 8.5.6, 8.0.0.RC1 to 8.0.38, 7.0.0 to 7.0.72, and 6.0.0 to 6.0.47 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 and/or obtain sensitive information from requests other then their own.
