HIGH

Glances Vulnerable to Command Injection via Dynamic Configuration Values

Title source: cna
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2026-33641. PoCs published by best.sell.

AI-analyzed exploit summary This PoC demonstrates a command injection vulnerability in Glances versions prior to 4.5.3, where backtick-enclosed substrings in configuration files are executed as system commands. The exploit creates a malicious config file and verifies command execution by checking for a created file.

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.
