DescriptionCVE.org

PowerJob Worker version 5.1.2 (and likely earlier versions) exposes the /worker/deployContainer HTTP endpoint without authentication on the default transport port. This allows a remote attacker to execute arbitrary code.

AnalysisAI

Unauthenticated remote code execution in PowerJob Worker 5.1.2 (and likely earlier) stems from the /worker/deployContainer HTTP endpoint being reachable on the default transport port with no authentication, letting a remote attacker deploy and run an arbitrary container/module and thereby execute code on the worker host. PowerJob is a widely-forked open-source Java distributed job-scheduling framework, and the worker component is the execution plane that runs scheduled tasks. …

Vulnerability AssessmentAI

Exploitation Exploitation requires network reachability to the PowerJob worker's default transport (HTTP) port and that the /worker/deployContainer endpoint is served without authentication, which is the default per the description; no credentials, no user interaction, and no special configuration are needed against a default-configured worker version 5.1.2 or earlier. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine high-priority issue rather than a paper-critical one: the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/C:H/I:H/A:H, 9.8) describes network-reachable, no-authentication, no-interaction code execution, and that aligns cleanly with the description of an unauthenticated endpoint that deploys arbitrary containers. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No vendor-released fixed version is identified in the provided data, so treat patch status as unconfirmed and monitor the PowerJob project and its SECURITY.md (https://github.com/PowerJob/PowerJob/blob/master/SECURITY.md) for an updated release beyond 5.1.2. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify and inventory all PowerJob Worker instances running version 5.1.2 or earlier and assess network exposure; immediately implement network segmentation restricting access to the /worker/deployContainer endpoint to whitelisted trusted sources only. …
