Security readout for executives and security teams
Plain-English summary
This CVE affects Metasploit Framework users, not target networks in general. If an analyst runs the Telpho10 credential-dump module against a malicious HTTP server, that server can cause arbitrary file writes on the analyst's host. The business risk is compromise or disruption of security tooling and workstations, especially in research or assessment environments.
Executive priority
Treat this as a high-priority tooling hygiene issue for security teams, not a broad enterprise perimeter emergency. Prioritize inventory, user guidance, update verification, and isolation of assessment environments.
Technical view
The affected Metasploit module is auxiliary/admin/http/telpho10_credential_dump. Its untar handling is vulnerable to relative path traversal, allowing a malicious HTTP server to write files to arbitrary filesystem locations when the module is run. The CVSS 3.1 score is 8.1, with high integrity and availability impact and required user interaction.
Likely exposure
Exposure is likely limited to systems running Metasploit Framework versions named in the source bundle, 4.12.40 and 6.0.3, where users run the Telpho10 credential dump module against attacker-controlled or untrusted HTTP servers.
Exploitation context
The source bundle does not cite CISA KEV listing or active exploitation. Exploitation requires a user to run the vulnerable module against a malicious HTTP server, so the realistic threat is targeting security researchers, testers, or shared assessment infrastructure.
Researcher notes
Evidence supports path traversal during archive extraction in a specific Metasploit auxiliary module. The source bundle names arbitrary file write impact but does not provide official exploit-in-the-wild evidence or a specific patch version in the supplied data.
Mitigation direction
- Identify Metasploit Framework installations and versions in security workstations and assessment servers.
- Avoid running the Telpho10 credential-dump module against untrusted HTTP servers.
- Check Rapid7 guidance and the linked issue for fixed versions or official remediation.
- Run security tooling with least privilege and avoid elevated shells for routine module execution.
- Use isolated analysis environments for testing unfamiliar or potentially hostile services.
Validation and detection
- Confirm whether Metasploit Framework is installed on analyst workstations or shared testing hosts.
- Check installed versions against the CVE source bundle and Rapid7 issue.
- Verify whether auxiliary/admin/http/telpho10_credential_dump is present or used.
- Review logs, shell history, and assessment notes for use against untrusted HTTP endpoints.
- Inspect affected hosts for unexpected file writes after any relevant module execution.

Relative Path Traversal
Relative Path Traversal represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
