What to do
AI-suggested
- Restrict access to Datart instances strictly to trusted users and networks to minimize the risk of authenticated attackers.
- Implement strong authentication mechanisms, including multi-factor authentication, to reduce the risk of credential compromise.
- Apply rigorous input validation and sanitization on all user inputs, especially those interacting with template engines or SQL fields, to prevent injection of malicious template syntax.
- Monitor logs and application behavior for unusual template processing or execution patterns indicative of exploitation attempts.
- Isolate the Datart environment using network segmentation and least privilege principles to limit potential damage from a successful attack.
- Stay informed about vendor updates and apply patches promptly once available.
- Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SSTI payloads targeting Freemarker templates.
- Conduct security reviews and code audits focusing on template usage and input handling within Datart deployments.
Description
A Server-Side Template Injection (SSTI) vulnerability in the Freemarker template engine of Datart v1.0.0-rc.3 allows authenticated attackers to execute arbitrary code via injecting crafted Freemarker template syntax into the SQL script field.
