## Description

Glances is an open-source system cross-platform monitoring tool. Prior to
version 4.5.3, Glances supports dynamic configuration values in which
substrings enclosed in backticks are executed as system commands during
configuration parsing. This behavior occurs in Config.get\_value() and is
implemented without validation or restriction of the executed commands. If
an attacker can modify or influence configuration files, arbitrary commands
will execute automatically with the privileges of the Glances process
during startup or configuration reload. In deployments where Glances runs
with elevated privileges (e.g., as a system service), this may lead to
privilege escalation. This issue has been patched in version 4.5.3.
