Summary
Glances is a system monitoring tool that, from versions 4.0.8 to 4.5.5, has a vulnerability in the secure_popen() function. This function interprets redirection, pipe, and command chaining operators without validation, allowing unauthorized actions on the system.
Risk Assessment
An attacker can modify the Glances configuration file, enabling them to write arbitrary data to the filesystem and execute unauthorized commands. This poses a serious threat to the integrity and security of the system.
Recommendation
It is recommended to update Glances to version 4.5.5 or later to mitigate this vulnerability. Additionally, access to the configuration file should be restricted to prevent unauthorized modifications.
Original NVD description (English source)
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.
