Summary
Acunetix 360 identified a version disclosure (Tornado) in the target web server's HTTP response. Eclipse Tornado is a scalable, non-blocking web server and web application framework written in Python.
This information can help an attacker gain a greater understanding of the systems in use and potentially develop further attacks targeted at the specific version of Tornado.
Impact
An attacker might use the disclosed information to harvest specific security vulnerabilities for the version identified.
Remediation
Make use of RequestHandler.clear_header() to prevent information leakage from the SERVER header of its HTTP response:
RequestHandler.clear_header(‘Server’)
