Lifecycle Timeline
1DescriptionCVE.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.
