[原文]register.php in S8Forum 3.0 allows remote attackers to execute arbitrary PHP commands by creating a user whose name ends in a .php extension and entering the desired commands into the E-mail field, which creates a web-accessible .php file that can be called by the attacker, as demonstrated using a "system($cmd)" E-mail address with a "any_name.php" username.


        S8Forum 3.0版本的register.php存在漏洞。远程攻击者可以通过创建一个名称以.php拓展名结尾的用户以及输入E-mail字段需要的命令来执行任意PHP命令,该漏洞创建了一个可被攻击者调用的web-accessible .php文件,正如使用带有"any_name.php"用户名的"system($cmd)" 电子邮件地址。

S8Forum 3.0 Remote Command Execution Vulnerability (EDBID:22134)
php webapps
2003-01-06 Verified

N/A [点击下载]

S8Forum is prone to a remote command execution vulnerability.

When a user registers with the forum, a file is created locally with the specified username. The contents of this file will be the data entered by the user. As a result, a malicious user could create a file with an arbitrary name and PHP (.php) extension that contains valid PHP code. The attacker may then cause this file to be executed by requesting it via HTTP. 

- go to Register

- insert in Username:

- in password : any_pasword.

- in E-Mail:

<? system($cmd); ?>

Then request the following page:

S8Forum register.php Arbitrary Command Execution
Remote / Network Access Input Manipulation
Loss of Integrity
Exploit Public

- 漏洞描述

S8Forum contains a flaw that will allow a remote attacker to execute arbitrary commands. The problem is that user-supplied input upon submission to the 'register.php' script is not verified properly. It is possible for a remote attacker to pass arbitrary commands to the server in the name, email, or password field to be executed on the system resulting in a loss of integrity.
