9.8

CVSS v3.1

Official Description

Hertzbeat is a real-time monitoring system. In `CalculateAlarm.java`, `AviatorEvaluator` is used to directly execute the expression function, and no security policy is configured, resulting in AviatorScript (which can execute any static method by default) script injection. Version 1.4.1 fixes this vulnerability.

Risk Analysis

Hertzbeat contains a script injection vulnerability due to insecure use of AviatorScript in its alarm calculation component. This allows remote attackers to execute arbitrary static methods.

The vulnerability is remotely exploitable with low complexity, though no public exploit is currently known.

Recommended Action

Upgrade to Hertzbeat version 1.4.1 or later to implement required security policies for script execution.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-51388 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
