CVE-2021-44153Public exploitNetwork attack vector

Authenticated code execution via unvalidated ISV directive

Published Dec 13, 2021 · Updated Aug 4, 2024

Code execution in Reprise RLM 14.2 allows remote authenticated users to run arbitrary binaries through the administrative webserver. The license-file editor accepts an ISV directive naming a user-chosen executable and arguments, and RLM launches that program without an allowlist. Administrative access is required; execution occurs at server startup or when Reread/Restart Servers processes the edited license file.
