Executive Summary

CVE-2026-50979 is a command injection vulnerability in Osbil Technology oPanel v1.19.50 and earlier. It exists in the 'advanced/curl' component where improper input sanitization allows authenticated attackers to inject shell commands via the 'url' parameter. Attackers can bypass space restrictions using shell variables like ${IFS} and execute arbitrary OS commands with the web app's privileges.

Detection Guidance

To detect this vulnerability, monitor HTTP POST requests to /advanced/curl (typically on port 2083) for payloads containing shell command injection patterns like ;, &&, ||, or ${IFS} in the url parameter. Check server logs for suspicious commands such as id, whoami, or curl requests to external domains.

Impact Analysis

This vulnerability can lead to full system compromise, unauthorized data access, and potential lateral movement within the network. Attackers can execute OS commands with the privileges of the web application, allowing them to take control of the server or steal sensitive data.

Mitigation Strategies

Immediately update oPanel to the latest version beyond v1.19.50. If an update is unavailable, restrict access to /advanced/curl via firewall rules or disable the endpoint entirely. Implement strict input validation for the url parameter and enforce authentication with strong credentials.
