Detailsinfo

A vulnerability was found in HestiaCP up to 1.9.4. It has been rated as very critical. Affected by this issue is the function is_dns_record_format_valid/update_domain_zone of the component DNS Record Validator/Parser. The manipulation of the argument dns_record_type with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2025-30007 since 03/13/2025. The exploitation is known to be easy. The attack may be launched remotely.
