Title: Cherokee HTTPD Directory Traversal Vulnerability
Severity: HIGH
Description:
Cherokee is a compact web server which provides fast delivery of web content. It is freely available and distributed under the GPL. It runs on Linux and other Unix systems.
A vulnerability exists in Cherokee web server which may allow a remote attacker to display arbitrary files.
Cherokee is prone to directory traversal attacks. This is due to insufficient validation of externally supplied data, such as in web requests. By appending '../' sequences to a web request, it is possible for an attacker to break out of wwwroot and browse the filesystem of the host.
Furthermore, another issue is known to exist in Cherokee which increases the impact of this vulnerability dramatically. BugTraq ID 3771, "Cherokee HTTPD Insecure Privilege Release Vulnerability" describes a problem in which Cherokee web server fails to drop root privileges after binding to port 80. The implication is that an attacker may browse any file on the system, as the web server is running with root privileges.
