I discovered a command injection vulnerability in uniget that allows arbitrary command execution through the metadata loading and version check mechanism. ### 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. ### Details The vulnerable code is located in: `tool.go:250` Vulnerable function: ```go id="f2g0ic" func (tool *Tool) RunVersionCheck() (string, error) { cmd := exec.Command("/bin/bash", "-c", tool.Check+" | tr -d '\n'") version, err := cmd.Output() return string(version), nil } ``` The issue occurs because the `tool.Check` field is populated directly from metadata JSON files without validation. Related structure: ```go id="7f4yzm" type Tool struct {
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
