Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVE-2017-2829

Severity Medium
Score 6.5/10

Summary

An exploitable directory traversal vulnerability exists in the web management interface used by the Foscam C1 Indoor HD Camera running application firmware 2.52.2.37. A specially crafted HTTP request can cause the application to read a file from disk but a failure to adequately filter characters results in allowing an attacker to specify a file outside of a directory. An attacker can simply send an HTTP request to the device to trigger this vulnerability.

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.
