Detailsinfo

A vulnerability, which was classified as very critical, was found in Eclipse Kura up to 5.6.2. Affected is the function CommandCloudApp.execute of the component Command Execution. The manipulation of the argument workingDirectory with an unknown input leads to a sandbox vulnerability. CWE is classifying the issue as CWE-265. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In Kura versions <= 5.6.2, `CommandCloudApp.execute()` extracts a caller-supplied ZIP archive into a caller-supplied directory inside the Kura JVM process before dispatching the command to the executor service. On a packaged Kura installation the JVM runs as `kurad` with `CAP_DAC_OVERRIDE`, while the configurable "Unprivileged" executor drops to the `kura` user via `su`. A caller with permissions `rest.command` who is intentionally restricted to unprivileged command execution (`privileged.command.service.enable=false`, the default) can therefore set `workingDirectory` to `/` and use the ZIP body to write or overwrite arbitrary files on the device as `kurad`, completely bypassing the unprivileged sandbox the operator selected. The command service is disabled by default since Kura 4.0.0 [1]. The issue does not apply when the command service is disabled.
