DescriptionNVD

An eval() injection vulnerability in the Rapid7 Insight Agent beaconing logic for Linux versions could theoretically allow an attacker to achieve remote code execution as root via a crafted beacon response. Because the Agent uses mutual TLS (mTLS) to verify commands from the Rapid7 Platform, it is unlikely that the eval() function could be exploited remotely without prior, highly privileged access to the backend platform.

AnalysisAI

Remote code execution in Rapid7 Insight Agent for Linux versions prior to 4.1.0.2 allows authenticated attackers with high privileges to inject arbitrary code via eval() in the beaconing logic by crafting a malicious beacon response. The vulnerability requires high authentication privileges and mutual TLS verification, making remote exploitation difficult without prior compromise of the Rapid7 Platform backend. …
