CVE-2016-6816
CVSS v3.1
7.1
High
| Vector | AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L |
Name of the Vulnerable Software and Affected Versions
Apache Tomcat versions 9.0.0.M1 through 9.0.0.M11
Apache Tomcat versions 8.5.0 through 8.5.6
Apache Tomcat versions 8.0.0.RC1 through 8.0.38
Apache Tomcat versions 7.0.0 through 7.0.72
Apache Tomcat versions 6.0.0 through 6.0.47
Description
The code in Apache Tomcat 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 than their own.
Recommendations
For Apache Tomcat versions 9.0.0.M1 through 9.0.0.M11, update to a version outside of this range to resolve the issue.
For Apache Tomcat versions 8.5.0 through 8.5.6, update to a version outside of this range to resolve the issue.
For Apache Tomcat versions 8.0.0.RC1 through 8.0.38, update to a version outside of this range to resolve the issue.
For Apache Tomcat versions 7.0.0 through 7.0.72, update to a version outside of this range to resolve the issue.
For Apache Tomcat versions 6.0.0 through 6.0.47, update to a version outside of this range to resolve the issue.
As a temporary workaround, consider restricting access to the HTTP request line parsing functionality until a patch is available.
