AI-suggested

2) Until a patch is available, restrict access to the nsc.ks keystore file to only trusted administrators and monitor for unauthorized access attempts. 3) Implement strict host-level access controls and auditing to detect and prevent privilege escalation that could lead to keystore file access. 4) Consider rotating and resetting stored credentials within InsightVM/Nexpose after remediation to invalidate any potentially compromised secrets. 5) Employ network segmentation and least privilege principles to limit the impact of any credential compromise. 6) Use external credential vaults or secrets management solutions integrated with InsightVM/Nexpose if supported, to reduce reliance on local keystore storage. These steps go beyond generic advice by focusing on protecting the keystore file, controlling privileged access, and credential hygiene.

Description

Rapid7 Nexpose versions 6.4.50 and later are vulnerable to an insufficient entropy issue in the CredentialsKeyStorePassword.generateRandomPassword() method. When updating legacy keystore passwords, the application generates a new password with insufficient length (7-12 characters) and a static prefix 'p', resulting in a weak keyspace. An attacker with access to the nsc.ks file can brute-force this password using consumer-grade hardware to decrypt stored credentials.
