Festo: MSE6-C2M/D2M/E2M Incomplete User Documentation of Remote Accessible Functions

Festo — MSE6

Festo PSIRThigh

Published

Last update

Linked CVEs

Affected sectors

Risk evaluation

Incomplete user documentation of undocumented, authenticated test mode and further remote accessible functions. The supported features may be covered only partly by the corresponding user documentation. Festo developed the products according to the respective state of the art. As a result, the protocols used no longer fully meet today's security requirements. The products are designed and developed for use in sealed-off (industrial) networks. If the network is not adequately sealed off, unauthorized access to the product can cause damage or malfunctions, particularly Denial of Service (DoS) or loss of integrity.

Mitigation summary

Update of user documentation in next product version.
