Improper Control of Generation of Code ('Code Injection')
Ralf Image Gallery (RIG) 0.7.4 and other versions before 1.0, when register_globals is enabled, allows remote attackers to conduct PHP remote file inclusion and directory traversal attacks via URLs or ".." sequences in the (1) dir_abs_src parameter in (a) check_entry.php, (b) admin_album.php, (c) admin_image.php, and (d) admin_util.php; and the (2) dir_abs_admin_src parameter in admin_album.php and admin_image.php. NOTE: this issue can be leveraged to conduct cross-site scripting (XSS) attacks.
CWE-94 - Code Injection
Code injection is a type of vulnerability that allows an attacker to execute arbitrary code. This vulnerability fully compromises the machine and can cause a wide variety of security issues, such as unauthorized access to sensitive information, manipulation of data, denial of service attacks etc. Code injection is different from command injection in the fact that it is limited by the functionality of the injected language (e.g. PHP), as opposed to command injection, which leverages existing code to execute commands, usually within the context of a shell.
