In Page Banner Information Leak

  • Risk:

  • Low

  • Type:
  • Passive
Summary

The server returned a version banner string in the response content. Such information leaks may allow attackers to further target specific issues impacting the product and version in use.

Solution

Configure the server to prevent such information leaks. For example: Under Tomcat this is done via the "server" directive and implementation of custom error pages. Under Apache this is done via the "ServerSignature" and "ServerTokens" directives.

Other info
There is a chance that the highlight in the finding is on a value in the headers, versus the actual matched string in the response body.
