Security readout for executives and security teams
Plain-English summary
This flaw affects a Metasploit post-exploitation module used by security teams. If an analyst runs the vulnerable OS X enumeration module against a malicious host, that host can influence the module into writing files outside the intended location on the analyst’s machine.
Executive priority
Treat as high priority for security operations teams using Metasploit. The business risk is compromise or disruption of analyst systems, not broad customer-facing exposure based on the provided sources.
Technical view
CVE-2020-7376 is a relative path traversal in Metasploit Framework’s post/osx/gather/enum_osx module, specifically get_keychains. The CVSS 3.1 score is 7.1, with local attack vector and required user interaction. The documented impact is arbitrary file writes to arbitrary filesystem locations on the host running the module.
Likely exposure
Exposure is most likely on security workstations, lab systems, or automation hosts running the affected Metasploit Framework module against untrusted or malicious OS X targets. It is not described as an internet-facing service issue.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires the vulnerable module to be run on a malicious host, so risk depends on analyst workflow and tool isolation.
Researcher notes
Affected versions listed in the bundle are Metasploit Framework 4.11.7 and 6.0.3. Evidence is limited to the CVE record and Rapid7 issue reference; do not assume broader affected ranges, active exploitation, or specific patches without vendor confirmation.
Mitigation direction
- Check Rapid7 guidance and issue 14008 for remediation details.
- Upgrade Metasploit Framework to a vendor-supported fixed release when confirmed.
- Avoid running the affected enum_osx module against untrusted hosts until remediated.
- Run security tooling from isolated, least-privileged analysis environments.
Validation and detection
- Inventory Metasploit Framework installations and versions.
- Identify usage of post/osx/gather/enum_osx in engagements or automation.
- Review whether the module was run against untrusted OS X hosts.
- Check affected analyst systems for unexpected filesystem writes after module execution.
