Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Absolute path traversal vulnerability in SugarCRM Sugar Community Edition 4.5.1 and 5.0.0 allows remote attackers to read arbitrary files via a full path in the URL parameter to modules/Feeds/Feed.php, which places the contents into a related cache file in the .cache/feeds directory.
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.
