• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days

Description

Rapid7 Nexpose and InsightVM versions prior to 6.6.172 failed to reliably validate the authenticity of update contents. This failure could allow an attacker to provide a malicious update and alter the functionality of Rapid7 Nexpose. The attacker would need some pre-existing mechanism to provide a malicious update, either through a social engineering effort, privileged access to replace downloaded updates in transit, or by performing an Attacker-in-the-Middle attack on the update service itself.

Affected products

• Rapid7 InsightVM: before 6.6.172 — fixed in 6.6.172
• Rapid7 Nexpose: before 6.6.172 — fixed in 6.6.172

How to fix

Upgrade to a fixed version: Rapid7 InsightVM 6.6.172; Rapid7 Nexpose 6.6.172. Check the vendor advisory for mitigations.
