Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The Tomcat 4.1-based Servlet Service in Fujitsu Interstage Application Server 7.0 through 9.0.0 and Interstage Apworks/Studio 7.0 through 9.0.0 allows remote attackers to obtain sensitive information (web root path) via unspecified vectors that trigger an error message, probably related to enabling the useCanonCaches Java Virtual Machine (JVM) option.
CWE-22 - Path Traversal
Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
