Tomcat is the Apache Jakarta Project's official implementation of Java Servlets and Java Server Pages.
The following vulnerabilities were reported:
- Delian Krustev discovered that the JULI logging component does not properly enforce access restrictions, allowing web application to add or overwrite files (CVE-2007-5342).
- When the native APR connector is used, Tomcat 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 (CVE-2007-6286).
- If the processing or parameters is interrupted, i.e. by an exception, then it is possible for the parameters to be processed as part of later request (CVE-2008-0002).
- An absolute path traversal vulnerability exists due to the way that WebDAV write requests are handled (CVE-2007-5461).
- Tomcat does not properly handle double quote (") characters or %5C (encoded backslash) sequences in a cookie value, which might cause sensitive information such as session IDs to be leaked to remote attackers and enable session hijacking attacks (CVE-2007-5333).
These vulnerabilities can be exploited by:
- a malicious web application to add or overwrite files with the permissions of the user running Tomcat.
- a remote attacker to conduct session hijacking or disclose sensitive data.
There is no known workaround at this time.
