Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVE-2023-34254

High
7.6/10

Summary

The GLPI Agent is a generic management agent. Prior to version 1.5, if glpi-agent is running remoteinventory task against an Unix platform with ssh command, an administrator user on the remote can manage to inject a command in a specific workflow the agent would run with the privileges it uses. In the case, the agent is running with administration privileges, a malicious user could gain high privileges on the computer glpi-agent is running on. A malicious user could also disclose all remote accesses the agent is configured with for remoteinventory task. This vulnerability has been patched in glpi-agent 1.5.

CWE-78 - OS Command Injection

The OS command injection weakness (also known as shell injection) is a vulnerability which enables an attacker to run arbitrary OS commands on a server. This is done by modifying the intended downstream OS command and injecting arbitrary commands, enabling the execution of unauthorized OS commands. This has the potential to fully compromise the application along with all of its data, and, if the compromised process does not follow the principle of least privileges, it may compromise other parts of the hosting infrastructure as well. This weakness is listed as number ten in the 'CWE Top 25 Most Dangerous Software Weaknesses'.
