Weakness

Incomplete Documentation  (CWE-1059) 

Summary

In multiple products by Festo a remote unauthenticated attacker could use functions of undocumented protocols which could lead to a complete loss of confidentiality, integrity and availability.


Impact

Please consult the CVE details above.

Solution

Mitigation

Update of technical user manual documentation in next product version.

Additionally, please refer to the following Recommendations

Users running communication over an untrusted network who require full protection should switch to an alternative solution such as running the communication over a VPN.

Festo strongly recommends to minimize and protect network access to connected devices with state of the art techniques and processes. For a secure operation follow the recommendations in the product manuals and note the protocols and their supported features in Festo Field Device Tool or Festo Automation Suite online help.

As part of a security strategy, Festo recommends the following general defense measures to reduce the risk of exploits: - Use controllers and devices only in a protected environment to minimize network exposure and ensure that they are not accessible from outside

- Use firewalls to protect and separate the control system network from other networks

- Use VPN (Virtual Private Networks) tunnels if remote access is required

- Activate and apply user management and password features

- Use encrypted communication links

- Limit the access to both development and control system by physical means, operating system features, etc.

- Protect both development and control system by using up to date virus detecting solutions
