[原文]registration.PHP in ATutor 1.5.1 pl2 allows remote attackers to execute arbitrary SQL commands via an e-mail address that ends in a NULL character, which bypasses the PHP regular expression check. NOTE: it is possible that this is actually a bug in PHP code, in which case this should not be treated as a vulnerability in ATutor.


[CNNVD]ATutor Registration.PHP SQL注入漏洞(CNNVD-200512-184)

        ATutor 1.5.1 pl2中的registration.PHP存在SQL注入漏洞,远程攻击者可以通过以空字符结尾的电子邮件地址(这可绕过PHP正则表达式检查)执行任意SQL命令。

ATutor registration.php Email Field SQL Injection
Remote / Network Access Information Disclosure, Input Manipulation
Loss of Confidentiality, Loss of Integrity

- 漏洞描述

ATutor contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the registration.php script not properly sanitizing user-supplied input to the 'email' field. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
