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

CVE-2026-45152

Low
0/10

Summary

A Command Injection vulnerability exists in uniget due to unsafe execution of the 'check' field from metadata files using '/bin/bash -c'. Because the 'check' field is loaded directly from untrusted JSON metadata without validation or sanitization, an attacker can craft malicious metadata that executes arbitrary shell commands on the victim's system when common uniget operations such as 'describe', 'install', 'update', or 'inspect' are performed. This vulnerability can lead to Arbitrary Code Execution with the privileges of the user running uniget. This issue affects versions prior to 0.27.1.

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'.
