Multiple directory traversal vulnerabilities in CyBoards PHP Lite 1.21 allow remote attackers to include and execute arbitrary local files via directory traversal sequences in the (1) script_path parameter to (a) options.php and the (2) lang_code parameter to (b) copy_vip.php and (c) process_edit_board.php in adminopts/. NOTE: some of these vectors might not be vulnerabilities under proper installation.
In order to exploit this vulnerability to execute arbitrary code, the attacker would first be required to upload a malicious file or inject arbitrary commands into an existing file and register_globals must be enabled.
CVSS Severity (version 2.0):
Impact Subscore: 6.4
Exploitability Subscore: 4.9
CVSS Version 2 Metrics:
Access Vector: Network exploitable
Access Complexity: High
Authentication: Not required to exploit
Impact Type: Allows unauthorized disclosure of information; Allows unauthorized modification; Allows disruption of service
