| Título | DTStack Taier <=1.0.0 Code Injection |
|---|
| Descrição | A vulnerability was found in DTStack Taier up to 1.0.0. It has been classified as critical. Affected is the function preHandle of the file taier-data-develop/src/main/java/com/dtstack/taier/develop/interceptor/LoginInterceptor.java. The LoginInterceptor only checks whether the authentication token cookie is blank without verifying its signature or validity. This allows an unauthenticated attacker to bypass authentication by setting any non-empty token cookie value. Combined with a JDBC URL injection in the data source connection test endpoint (ConnFactory.java) and an outdated PostgreSQL JDBC driver (42.2.2, CVE-2022-21724 unfixed), a remote attacker can execute arbitrary commands on the server as root without any credentials. The attack can be initiated remotely.
