CVE-2024-43202: Apache DolphinScheduler code injection in task API

Executive brief

Apache DolphinScheduler is a workflow scheduling platform used to orchestrate data processing jobs and automated tasks. A code injection vulnerability in versions before 3.2.2 allows unauthenticated attackers to execute arbitrary code remotely, potentially compromising data confidentiality, integrity, and system availability. This vulnerability poses an immediate risk to organizations relying on DolphinScheduler for mission-critical automation.

Technical details

This is a code injection vulnerability (CWE-94) affecting Apache DolphinScheduler's task API module (dolphinscheduler-task-api). The vulnerability stems from improper control of code generation where externally-influenced input is used to construct code segments without proper neutralization of special elements. The vulnerability is exploitable remotely over the network without requiring authentication, privileges, or user interaction, as indicated by the CVSS v3.1 vector AV:N/AC:L/PR:N/UI:N. An attacker can achieve complete system compromise with high impact on confidentiality, integrity, and availability. Versions 3.1.0 through 3.2.1 are affected; patch version 3.2.2 is available and should be applied immediately.
