CVE-2021-32498 : Security Advisory and Response
Learn about CVE-2021-32498 affecting SICK SOPAS ET before 4.8.0, allowing attackers to run arbitrary executables through path traversal. Find mitigation steps here.
SICK SOPAS ET before version 4.8.0 allows attackers to manipulate the pathname of the emulator and use path traversal to run an arbitrary executable located on the host system. This can lead to the execution of unauthorized code when the user initiates the emulator, posing a significant security risk.
Understanding CVE-2021-32498
This section provides an overview of the impact, technical details, and mitigation strategies related to CVE-2021-32498.
What is CVE-2021-32498?
