Detailsinfo

A vulnerability was found in twentyhq twenty up to 1.16.7. It has been classified as critical. Affected is the function group_by of the file engine/api/graphql/graphql-query-runner/group-by/resolvers/utils/get-group-by-expression.util.ts of the component REST API groupBy Endpoint. The manipulation of the argument timeZone with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Twenty is an open source CRM. From 1.7.7 through 1.16.7, a critical Remote Code Execution (RCE) vulnerability exists in Twenty CRM via a chained SQL Injection and PostgreSQL COPY TO PROGRAM attack. If Postgres user is a super user then any authenticated user can execute arbitrary OS commands on the database server by injecting SQL through the unsanitized timeZone parameter in the REST API groupBy endpoint. The timeZone field within the group_by query parameter is directly interpolated into a raw SQL expression using JavaScript template literals without any parameterization, validation, or escaping. This affects engine/api/graphql/graphql-query-runner/group-by/resolvers/utils/get-group-by-expression.util.ts.
