Vulnerability from csaf_siemens - Published: 2021-04-13 00:00 - Updated: 2021-09-14 00:00Summary
SSA-187092: Several Buffer-Overflow Vulnerabilities in Web Server of SCALANCE X-200
Notes
Summary: Several SCALANCE X-200 switches contain buffer overflow vulnerabilities in the web server.
In the most severe case an attacker could potentially remotely execute code.
Siemens is preparing updates and recommends specific countermeasures for products where updates 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.
