Which versions of Hestiacp are affected by EUVD-2025-210452?

HestiaCP versions prior to 1.9.5 allow any authenticated control panel user to escalate privileges to root through DNS record injection, enabling complete host takeover.. A patch is available.

How to fix or mitigate EUVD-2025-210452?

Within 24 hours: Inventory all HestiaCP deployments and identify instances running versions before 1.9.5; assess active control panel user base. Within 7 days: Apply vendor patch to upgrade all affected instances to HestiaCP 1.9.5 or later; if patching cannot be completed, restrict control panel access to essential administrators only. Within 30 days: Confirm patch deployment across all production systems, audit DNS record modification logs for suspicious activity, and validate no unauthorized root-level access occurred during vulnerability window.

DescriptionCVE.org

HestiaCP before 1.9.5 contains an authenticated OS command injection vulnerability that allows low-privilege authenticated users to execute arbitrary commands as root by injecting a single-quote character into unvalidated DNS record types. Attackers can exploit insufficient input validation in is_dns_record_format_valid() combined with unsafe eval-based parsing in update_domain_zone() to prematurely close a variable assignment string and achieve full root code execution on the underlying host in a single DNS record creation step.

AnalysisAI

Privilege escalation to root in the HestiaCP web hosting control panel (versions before 1.9.5) lets any low-privilege authenticated user run arbitrary OS commands as root by injecting a single-quote into an unvalidated DNS record type field. The flaw chains weak input validation in is_dns_record_format_valid() with unsafe eval-based zone parsing in update_domain_zone(), turning a routine DNS record creation into full host takeover. No public exploit is identified at time of analysis, but VulnCheck has published a detailed advisory and the vendor shipped a fix in 1.9.5.
