SynopsisThe remote Apache Tomcat server is affected by multiple vulnerabilities.
DescriptionAccording to its self-reported version number, the instance of Apache Tomcat listening on the remote host is prior to 5.5.26. It is, therefore, affected by multiple vulnerabilities :
- The remote Apache Tomcat install may be vulnerable to an information disclosure attack via cookies. The previous fix for CVE-2007-3385 was incomplete and did not account for the use of quotes or '%5C' in cookie values.
- The default security policy in the JULI logging component did not restrict access permissions to files.
This could be misused by untrusted web applications to access and write arbitrary files in the context of the tomcat process. (CVE-2007-5342)
- The remote Apache Tomcat install may be vulnerable to an information disclosure attack via the WebDAV servlet.
Certain WebDAV requests, containing an entity with a SYSTEM tag can result in the disclosure of arbitrary file contents. (CVE-2007-5461)
- When the native APR connector is used, it does not properly handle an empty request to the SSL port, which allows remote attackers to trigger handling of a duplicate copy of one of the recent requests, as demonstrated by using netcat to send the empty request.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Apache Tomcat version 5.5.26 or later.
