Deeper analysis
Hardy Barth cPH2 eCharge Ladestation versions 1.87.0 and earlier contain an Execution with Unnecessary Privileges vulnerability, tracked as CVE-2023-46360 and assigned CWE-250. The flaw carries a CVSS 3.1 score of 8.8 with a network attack vector, low complexity, and low privileges required, resulting in high impact to confidentiality, integrity, and availability.
An authenticated remote attacker with low-privileged access can exploit the condition to run commands or processes at elevated privileges beyond those intended for the account. This enables full compromise of the charging station's operating environment without needing user interaction.
The associated EPSS score stands at 0.5512 with no indicated rise from a lower baseline. Public references point to vendor information at hardy.com and detailed analysis of related command-injection issues in the same product line, but no specific patch or mitigation guidance is supplied in the available data.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Policy promotes least privilege by defining necessary privileges and management commitment to them.
Supervision detects and allows removal of unnecessary privileges that enable execution with excess rights.
Reviewing accounts for compliance, disabling/removing unneeded accounts, and aligning with termination processes prevents execution with unnecessary privileges.
Separation of duties prevents any single user from holding all privileges needed to complete a critical task, directly reducing execution with unnecessary privileges.
Directly prevents execution with more privileges than needed for assigned tasks.
Role-based training on least privilege principles reduces the chance personnel assign or retain unnecessary privileges.
Analysis of audit records can identify execution with unnecessary privileges through unusual activity patterns.
Automatic termination after a defined period eliminates unnecessary privileges from persistent connections.
