Summary
SSA-238730: Out-of-Bounds Write Vulnerabilities in SITOP UPS1600 before V2.5.4

Notes

Summary
Multiple out-of-bounds vulnerabilities in third-party components are affecting SITOP UPS1600 before V2.5.4. Attackers could exploit these vulnerabilities and cause limited impact in the affected systems. Siemens has released new versions for the affected products and recommends to update to the latest versions.
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.
