Security readout for executives and security teams
Plain-English summary
This flaw can expose the administrator username and password for a Wanscam HW0021 network camera without authentication. If these cameras are reachable from untrusted networks, an attacker could gain camera administrator access and potentially use the device as a foothold.
Executive priority
Prioritize locating and isolating affected cameras where they are externally reachable or on shared networks. Treat confirmed exposure as urgent because the issue can disclose administrator credentials without login.
Technical view
CVE-2017-11510 is a CWE-200 information disclosure issue in Wanscam HW0021 firmware 11.6.5.1.1-20161213. The source states an unauthenticated remote attacker can recover administrator credentials through an ONVIF GetSnapshotUri request. No CVSS score is provided in the bundle.
Likely exposure
Exposure is likely limited to Wanscam HW0021 cameras running firmware 11.6.5.1.1-20161213, especially where ONVIF or camera services are reachable from the Internet, guest networks, or other untrusted segments.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation evidence. Tenable’s advisory reports unauthenticated remote credential recovery, which makes Internet-exposed devices materially risky even without confirmed exploitation.
Researcher notes
Evidence is narrow but clear: one affected product and firmware version are named, and the described impact is administrator credential disclosure. The bundle does not provide CVSS, patch details, CPEs, or exploitation confirmation.
Mitigation direction
- Inventory Wanscam HW0021 cameras and confirm firmware versions.
- Check Wanscam or vendor guidance for fixed firmware or replacement options.
- Block Internet and untrusted-network access to camera and ONVIF services.
- Place affected cameras on segmented networks with strict ACLs or VPN access.
- Rotate administrator credentials after isolation or remediation.
Validation and detection
- Confirm whether any HW0021 device runs firmware 11.6.5.1.1-20161213.
- Review firewall and exposure data for reachable camera or ONVIF services.
- Check device logs for suspicious unauthenticated ONVIF access if logs are available.
- Verify segmentation prevents untrusted hosts from reaching affected camera services.

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.
