A BeanShell interpreter in remote server mode runs in OpenMNS Horizon versions earlier than 32.0.2 and in related Meridian versions which could allow arbitrary remote Java code execution. The solution is to upgrade to Meridian 2023.1.6, 2022.1.19, 2021.1.30, 2020.1.38 or Horizon 32.0.2 or newer. Meridian and Horizon installation instructions state that they are intended for installation within an organization's private networks and should not be directly accessible from the Internet.
CVE-2023-40313
This high-severity CVE scores 7.1 under NVD CVSS v3. EPSS exploit probability: 0.8% (54th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
