Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Directory traversal vulnerability in Oracle Reports 6.0, 6i, 9i, and 10g allows remote attackers to overwrite arbitrary files via (1) "..", (2) Windows drive letter (C:), and (3) absolute path sequences in the desname parameter. NOTE: this issue was probably fixed by REP06 in CPU Jan 2006, in which case it overlaps CVE-2006-0289.
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.
