[nuclei-template] CNVD-2017-06001 Dahua DSS SQL injection

[shibeta]

Template Information:

Dahua DSS Digital Surveillance System is a security video monitoring system developed by Dahua.

A SQL injection vulnerability exists within Dahua DSS. Attackers can send specially crafted data packets to the attachment_clearTempFile.action or attachment_getAttList.action route, exploiting error-based injection to acquire sensitive information from the database. Beyond obtaining information from the database such as administrator credentials and personal information of users on the site, attackers could potentially write trojans to the server with sufficient privileges and further gain system-level access.

Relevant vulnerability ID: CNVD-2017-06001
