Security readout for executives and security teams
Plain-English summary
CVE-2019-5640 is a low-severity information exposure issue in Rapid7 Nexpose before 6.6.114. After an inactive session ends, details from the last page a previous user viewed may remain visible locally in the browser. The main business risk is limited disclosure on shared or unattended admin workstations.
Executive priority
Treat this as a low-priority hygiene fix unless Nexpose is commonly used from shared workstations. It should be remediated during routine vulnerability maintenance, with faster action for environments handling sensitive scan results on shared admin systems.
Technical view
The issue is classified as CWE-200 with CVSS 3.1 score 3.3 and vector AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N. Sources describe browser-side exposure after timeout/logout, where prior page details can remain accessible locally. Integrity and availability are not indicated as impacted.
Likely exposure
Exposure is most plausible where Nexpose is accessed from shared, unlocked, or poorly controlled administrative browsers. Internet-facing exposure is not supported by the provided CVSS vector or description.
Exploitation context
The source bundle does not indicate active exploitation, and the CVE is not listed as KEV. Practical abuse appears to require local access and low privileges, with value depending on what the previous Nexpose page displayed.
Researcher notes
The provided affected metadata is sparse and somewhat inconsistent, listing Nexpose with version 1.0 while the description states versions prior to 6.6.114. Use the narrative version boundary and Rapid7 reference, but verify against vendor release notes before final scoping.
Mitigation direction
- Upgrade Nexpose to 6.6.114 or later, based on the affected-version statement.
- Review Rapid7 release notes and current vendor guidance for any additional instructions.
- Restrict Nexpose console access to trusted administrative workstations.
- Enforce screen locking, browser closure, and session hygiene on shared systems.
Validation and detection
- Inventory Nexpose deployments and compare versions against 6.6.114.
- Confirm administrative access paths are limited to controlled workstations.
- Review whether shared browsers are used for Nexpose administration.
- In a non-production lab, verify timeout behavior without exposing sensitive data.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
