Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
A relative path traversal vulnerability in a "FileUtil" class used by the PEAR management component of Apache UIMA allows an attacker to create files outside the designated target directory using carefully crafted ZIP entry names. This issue affects Apache UIMA Apache UIMA version prior to 3.3.1. Note that PEAR files should never be installed into an UIMA installation from untrusted sources because PEAR archives are executable plugins that will be able to perform any actions with the same privileges as the host Java Virtual Machine.
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.
