Exploitation vector: Network

Exploit availability: No

Vulnerable software:
iCMS
Web applications / CMS

Vendor: iCMS

Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data via admincp.php?app=spider&do=import_rule because the upfile content is base64 decoded, deserialized, and used for database insertion in spider.admincp.php in iCMS v7.0.11. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.

Mitigation
Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
