Advisory Details:
High-Tech Bridge Security Research Lab discovered vulnerability in AdRotate, which can be exploited to perform SQL Injection attacks.
1) SQL Injection in AdRotate: CVE-2014-1854
The vulnerability exists due to insufficient validation of "track" HTTP GET parameter passed to
"/wp-content/plugins/adrotate/library/clicktracker.php" script. A remote unauthenticated attacker can execute arbitrary SQL commands in application's database.
The following PoC code contains a base64-encoded string "-1 UNION SELECT version(),1,1,1", which will be injected into SQL query and will output MySQL server version:
http:///wp-content/plugins/adrotate/library/clicktracker.php?track=LTEgVU5JT04gU0VMRUNUIHZlcnNpb24oKSwxLDEsMQ==
Successful exploitation will result in redirection to local URI that contains version of the MySQL server:
http:///wp-content/plugins/adrotate/library/5.1.71-community-log
-----------------------------------------------------------------------------------------------
Solution:
Update to AdRotate 3.9.5

感谢Diana分享这个详细的漏洞信息。这个SQL注入漏洞（CVE-2014-1854）风险评级为高，而且攻击者无需认证即可利用，影响还是比较严重的。好在官方在漏洞公开后很快发布了3.9.5版本修复，使用AdRotate插件的朋友建议尽快更新到最新版，避免被攻击。也提醒大家关注插件更新日志，及时打补丁是防范此类问题最有效的方法。Re: Wordpress AdRotate Plugin 3.9.4 - (clicktracker.php, track param) - SQL Injec...
感谢分享这个漏洞信息。这是一个典型的未认证SQL注入，攻击者只需构造特制的`track`参数就能在数据库上执行任意查询，风险确实很高。CVSS 7.5分说明影响面不小，好在官方在1月31日就发布了3.9.5修复版本。如果你或者身边的人还在用AdRotate 3.9.4或更早版本，建议尽快升级到3.9.5以上，避免被攻击者利用。另外注意检查服务器日志，避免已有被利用的痕迹。Re: Wordpress AdRotate Plugin 3.9.4 - (clicktracker.php, track param) - SQL Injec...
这个SQL注入漏洞看起来挺严重的，未授权远程攻击者就能通过clicktracker.php的track参数执行任意SQL命令，CVSS评分7.5确实不低。好消息是厂商响应很快，1月30号报漏洞，31号就打了补丁，建议还在用3.9.4及之前版本的用户赶紧升级到3.9.5。另外PoC里提到了通过UNION SELECT获取MySQL版本号，实际利用可能危害更大，建议同时检查一下日志看有没有被尝试攻击的痕迹。WordPress插件这种第三方组件确实容易成为突破口，定期更新很重要。
