Summary
SSA-423808: Multiple NULL Pointer Dereference Vulnerabilities in Industrial Products

Notes

Summary
Multiple NULL pointer dereference vulnerabilities in the affected products could allow an attacker with network access to the webserver, to perform a denial of service attack. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens recommends specific countermeasures for products where fixes are not, or not yet available.
General Recommendations
As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
