Doc Text:
A flaw was found in Glances, an open-source system monitoring tool. The `secure_popen()` function, which executes system commands, fails to properly validate command strings, allowing special operators like file redirection and command chaining to be interpreted. An attacker who can modify the Glances configuration file can leverage this vulnerability to execute arbitrary commands or write arbitrary content to files on the system. This could lead to unauthorized code execution and data manipulation.

Description OSIDB Bzimport 2026-06-25 19:03:47 UTC 
Glances is an open-source system cross-platform monitoring tool. From 4.0.8 until 4.5.5, the secure_popen() function in glances/secure.py interprets > (file redirection), | (pipe), and && (command chaining) operators in command strings. These operators are applied without any validation on the target file path, piped command, or chained command. When Application Monitoring Process (AMP) modules load their command or service_cmd configuration values from glances.conf, those values are passed directly to secure_popen() with no sanitization. This allows an attacker who can modify the Glances configuration file to write arbitrary content to arbitrary filesystem paths (via >), chain arbitrary commands (via &&), or pipe command output to arbitrary programs (via |). This vulnerability is fixed in 4.5.5.
