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

CVE-2024-1881

High
9.8/10

Summary

AutoGPT, a component of significant-gravitas/autogpt, is vulnerable to improper neutralization of special elements used in an OS command ('OS Command Injection') due to a flaw in its shell command validation function. The issue arises from the application's method of validating shell commands against an "allowlist" or "denylist", where it only checks the first word of the command. This allows an attacker to bypass the intended restrictions by crafting commands that are executed despite not being on the "allowlist" or by including malicious commands not present in the "denylist". Successful exploitation of this vulnerability could allow an attacker to execute arbitrary shell commands. This vulnerability affects autogpt versions 0.4.0 through 0.5.0.

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'.
