Publication date: 2026-10-04

Last updated on: 2026-10-04

Assigner: VulnCheck

Description
Cockpit CMS 2.12.0 before 2.14.1 disables TLS certificate verification in the cron.php web worker restart request, allowing network attackers to capture the worker token. Man-in-the-middle attackers on the outbound path to site_url can present any certificate to steal the worker/web/token value and start the web worker.

Executive Summary

CVE-2026-105217 is a vulnerability in Cockpit CMS versions 2.12.0 through 2.14.0 where TLS certificate verification is disabled in the cron.php file. This allows man-in-the-middle attackers to intercept and steal the worker token by presenting a malicious certificate, enabling unauthorized access to admin functions.

Detection Guidance

Check Cockpit CMS version with: curl -s http://your-cockpit-domain.com/cockpit | grep -i version. If version is 2.12.0 to 2.14.0, it is vulnerable. Inspect cron.php for CURLOPT_SSL_VERIFYPEER set to false or CURLOPT_SSL_VERIFYHOST set to 0.

Impact Analysis

An attacker could capture the worker token and use it to execute arbitrary cron jobs or admin actions as if they were authenticated. This could lead to unauthorized data access, modification, or service disruption. The impact is limited to network paths where the attacker can intercept traffic.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating confidentiality requirements in GDPR and HIPAA. If exploited, it may result in data breaches, requiring notifications and potential penalties under these regulations.

Mitigation Strategies

Upgrade Cockpit CMS to version 2.14.1 or later. If immediate upgrade is not possible, manually edit cron.php to set CURLOPT_SSL_VERIFYPEER to true and CURLOPT_SSL_VERIFYHOST to 2. Restrict network access to cron.php endpoints.
