Summary
SSA-478893: TightVNC Vulnerabilities in Industrial Products (Revoked)

Notes

Summary
Multiple TightVNC (V1.x) vulnerabilities could allow remote code execution and Denial-of-Service attacks under certain conditions. Siemens has previously released this advisory containing a set of products that were considered to be affected. Through Siemens' continuous investigation processes it was identified that all products previously advised are not affected by any vulnerability listed in this advisory.
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.
