Vulnerability Description

Pterodactyl is a free, open-source game server management panel. Prior to version 1.11.11, using the /locales/locale.json with the locale and namespace query parameters, a malicious actor is able to execute arbitrary code without being authenticated. With the ability to execute arbitrary code it could be used to gain access to the Panel’s server, read credentials from the Panel’s config, extract sensitive information from the database, access files of servers managed by the panel, etc. This issue has been patched in version 1.11.11. There are no software workarounds for this vulnerability, but use of an external Web Application Firewall (WAF) could help mitigate this attack.

  1. Maintain the observed Atomicorp protections. Keep your Atomicorp commercial rules current and confirm that the selected observed rules (340007 ) have not been locally disabled. Atomicorp commercial rules are enabled by default. If you use Atomic WAF, review the applicable policy and rule settings.

  2. Apply the vendor’s remediation. WAF protection is defense in depth and does not replace upgrading or following the affected vendor’s guidance.

    • Affected versions: pterodactyl panel version < 1.11.11.
    • No specific CNA/vendor solution or workaround is included in the current CVE Record . Review the vendor’s security advisories and supported-release guidance before making changes.

  3. Validate after changes. Confirm rule updates are current, review WAF events for the affected application, and test application behavior after vendor upgrades, mitigations, or local policy changes.

Research Notes

Atomicorp WAF protections are designed around attack techniques and exploit behaviors, allowing existing protections to apply across multiple vulnerabilities without requiring a unique rule for every CVE.

Research Note Context

This research note documents exploit-technique analysis associated with this vulnerability and references Atomicorp WAF protections observed during engineering review, testing, or validation activities.

Atomicorp security controls are generally designed to identify and mitigate attack techniques and exploit behaviors rather than individual CVE identifiers. As a result, protections developed for one vulnerability may also apply to related attack variants and future vulnerabilities using similar techniques.
