Apache Tomcat 7.x < 7.0.12 Multiple Vulnerabilities

Synopsis :

The remote web server is affected by multiple vulnerabilities.

Description :

According to its self-reported version number, the instance of Apache
Tomcat 7.x listening on the remote host is prior to 7.0.12. It is,
therefore, affected by multiple vulnerabilities :

- A fix for CVE-2011-1088 introduced a security bypass
vulnerability. If login configuration data is absent
from the 'web.xml' file and a web application is
marked as 'metadata-complete', security constraints are
ignored and may be bypassed by an attacker. Please note
this vulnerability only affects version 7.0.11 of
Tomcat. (CVE-2011-1183)

- Several weaknesses were found in the HTTP Digest
authentication implementation. The issues are as
follows: replay attacks are possible, server nonces
are not checked, client nonce counts are not checked,
'quality of protection' (qop) values are not checked,
realm values are not checked, and the server secret is
a hard-coded, known string. The effect of these issues
is that Digest authentication is no stronger than Basic
authentication. (CVE-2011-1184, CVE-2011-5062,
CVE-2011-5063, CVE-2011-5064)

- Updates to the HTTP BIO connector, in support of
Servlet 3.0 asynchronous requests, fail to completely
handle HTTP pipelining. Sensitive information may be
disclosed because responses from the server can be
improperly returned to the wrong request and possibly
to the wrong user. (CVE-2011-1475)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.
