Camunda 7

Camunda 7.24.0 before 7.24.14 and 7.23.0 before 7.23.17 contains an expression injection vulnerability where AdhocQueryValidator.validate() fails to check sub-query expression maps within the orQueries field exposed by TaskQueryDto, allowing authenticated users to bypass the enableExpressionsInAdhocQueries restriction. Attackers can supply a malicious JUEL expression such as dueAfterExpression inside an orQueries entry to achieve arbitrary Java reflection and invoke java.lang.Runtime.exec, resulting in operating-system command execution as the engine service user.

Camunda 7.24.0 before 7.24.16 and 7.23.0 before 7.23.17 contains an authorization bypass vulnerability in the Cockpit webapp that allows authenticated attackers to bypass permission checks due to an inverted comparison logic in AbstractCockpitPluginResource.isPermissionDisabled(). Attackers with minimal Cockpit access can exploit a non-empty disabledPermissions configuration to read all process instances, process definitions, and incidents engine-wide without triggering any logging, regardless of their actual data grants.

Camunda 7.24.0 before 7.24.14 and 7.23.0 before 7.23.17 contains a missing authorization check vulnerability in engine-rest task sub-resources that allows authenticated attackers with no permission grants to access task comments and attachments by calling singular read and delete endpoints that lack the authorization-filtered checks enforced on their corresponding list endpoints. Using only a known object ID, attackers can exploit TaskAttachmentResourceImpl and TaskCommentResourceImpl methods such as getAttachment, getAttachmentData, deleteAttachment, and getComment to read or download task attachments and comments and to permanently delete task attachments.
