Vulnerability from csaf_siemens - Published: 2021-12-14 00:00 - Updated: 2021-12-14 00:00Summary
SSA-802578: Multiple File Parsing Vulnerabilities in JTTK before V11.1.1.0 and JT Utilities before V13.1.1.0
Notes
Summary
JT Open Toolkit (JTTK) before V11.1.1.0 contains multiple vulnerabilities that could be triggered when it reads a maliciously crafted JT file. These vulnerabilities also affects JT Utilities before V13.1.1.0. If a user is tricked to open a malicious JT file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution.
Siemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products.
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.
