CVE-2026-53925
Description
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.

Confidentiality,Integrity,Availability,Non-Repudiation
Technical Impact: Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart; Read Files or Directories; Modify Files or Directories; Read Application Data; Modify Application Data; Hide Activities
Attackers could execute unauthorized operating system commands, which could then be used to disable the product, or read and modify data for which the attacker does not have permissions to access directly. Since the targeted application is directly executing the commands instead of the attacker, any malicious activities may appear to come from the application or the application's owner.
