Security readout for executives and security teams
Plain-English summary
This CVE describes an access-control logic flaw in specific i3 International Annexxus camera builds. A restriction meant to prevent multiple administrator accounts can be bypassed, allowing an additional admin account. The business risk is unauthorized persistent control of surveillance devices if camera management access is reachable.
Executive priority
Prioritize assessment where these cameras support physical security, regulated environments, or internet-accessible sites. Without active exploitation evidence or a named patch, treat this as urgent inventory and access-control work rather than an emergency rebuild.
Technical view
The record names Annexxus Camera Ax46 V5.2.0 build 150317, Ax68 V5.0.9 build 151106, and Ax78 V5.0.9 build 150615. The flaw involves parameter manipulation and the UserPermission endpoint changing a created account to admin userType. Public sources do not provide CVSS, CWE, prerequisites, or vendor remediation details.
Likely exposure
Exposure is most likely where affected Annexxus camera management interfaces are reachable by untrusted networks or weakly controlled internal users. The source bundle does not prove exposure for other models, versions, or vendors.
Exploitation context
The provided sources describe a bypass method at a high level, but do not show active exploitation. CISA KEV status is false in the bundle. Authentication requirements and real-world exploit prevalence are not established.
Researcher notes
Evidence is narrow but specific: affected builds and the administrative-account impact are described. Missing items include CVSS, CWE, exploit prerequisites, vendor advisory status, and patch information. Do not generalize beyond the named Annexxus models and builds without independent confirmation.
Mitigation direction
- Identify any Ax46, Ax68, or Ax78 cameras matching the listed firmware builds.
- Check i3 International guidance for fixed firmware or supported remediation.
- Restrict camera management interfaces to trusted admin networks or VPN only.
- Audit and remove unexpected administrator accounts on affected devices.
- Harden credentials and review access permissions for camera administration.
Validation and detection
- Inventory camera model, firmware version, and build number against the CVE record.
- Review configured users for unauthorized or duplicate administrator accounts.
- Check administrative logs for unexpected account changes or permission updates.
- Confirm management interfaces are not exposed to the public internet.
- Track vendor advisories for patch or configuration guidance.
