Apache Tomcat 6.0.x < 6.0.36 Multiple Vulnerabilities

Synopsis :

The remote Apache Tomcat server is affected by multiple

Description :

According to its self-reported version number, the instance of Apache
Tomcat 6.0 listening on the remote host is prior to Tomcat 6.0.36. It
is, therefore, affected by multiple vulnerabilities :

- A flaw exists within the parseHeaders() function that
allows for a crafted header to cause a remote denial of
service. (CVE-2012-2733)

- An error exists related to FORM authentication that
allows a security bypass if 'j_security_check' is
appended to the request. (CVE-2012-3546)

- An error exists in the file
'filters/CsrfPreventionFilter.java' that allows
cross-site request forgery (XSRF) attacks to bypass
the filtering. This can allow access to protected
resources without a session identifier. (CVE-2012-4431)

- An error exists related to the 'NIO' connector when
HTTPS and 'sendfile' are enabled that can force the
application into an infinite loop. (CVE-2012-4534)

- Replay-countermeasure functionality in HTTP Digest
Access Authentication tracks cnonce values instead of
nonce values, which makes it easier for attackers to
bypass access restrictions by sniffing the network for
valid requests. (CVE-2012-5885)

- The HTTP Digest Access Authentication implementation
caches information about the authenticated user, which
allows an attacker to bypass authentication via session
ID. (CVE-2012-5886)

- The HTTP Digest Access Authentication implementation
does not properly check for stale nonce values with
enforcement of proper credentials, which allows an
attacker to bypass restrictions by sniffing requests.

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