Apache Tomcat 7.0.11, when web.xml has no login configuration, does not follow security constraints, which allows remote attackers to bypass intended access restrictions via HTTP requests to a meta-data complete web application. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-1088 and CVE-2011-1419.

The remote host is affected by the vulnerability described in GLSA-201206-24 (Apache Tomcat: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Apache Tomcat. Please       review the CVE identifiers referenced below for details.
  Impact :

    The vulnerabilities allow an attacker to cause a Denial of Service, to       hijack a session, to bypass authentication, to inject webscript, to       enumerate valid usernames, to read, modify and overwrite arbitrary files,       to bypass intended access restrictions, to delete work-directory files,       to discover the server&rsquo;s hostname or IP, to bypass read permissions for       files or HTTP headers, to read or write files outside of the intended       working directory, and to obtain sensitive information by reading a log       file.
  Workaround :

    There is no known workaround at this time.

Versions of Tomcat 7.0.x earlier than 7.0.12 are potentially affected by multiple vulnerabilities : 

  - An information disclosure exists in the HTTP BIO connector. (CVE-2011-1475)

  - A security bypass vulnerability exists due to a regression in the fix for CVE-2011-1088.  Note that this issue only affects Tomcat 7.0.11.(CVE-2011-1183)

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