Security readout for executives and security teams
Plain-English summary
Certain older Ubiquiti wireless ISP devices can be remotely compromised if exposed. The flaw lets an unauthenticated attacker inject operating-system commands through the Show AP info request. Business impact can include device takeover, service disruption, network foothold, and loss of confidentiality, integrity, and availability.
Executive priority
Treat this as urgent for any legacy Ubiquiti wireless infrastructure, particularly exposed devices. It is critical severity, remotely reachable without authentication, and listed by CISA as known exploited. Prioritize inventory, isolation, and firmware remediation.
Technical view
CVE-2010-5330 is command injection in stainfo.cgi on certain Ubiquiti devices because the ifname parameter is not sanitized. CVSS 3.1 is 9.8: network-accessible, low complexity, no privileges, no user interaction. Fixed versions cited are v4.0.1 for 802.11 ISP products, v5.3.5 for AirMax ISP products, and v5.4.5 for AirSync firmware.
Likely exposure
Exposure is most likely on legacy Ubiquiti AirOS, AirMax ISP, AirSync, and related 802.11 ISP wireless products, especially internet-reachable management interfaces. The provided affected-product metadata is incomplete, but Nanostation5 running Air OS is specifically cited as affected.
Exploitation context
CISA KEV lists CVE-2010-5330, which supports known exploitation in the wild. The source bundle also includes an Exploit-DB reference, indicating public exploit information exists. The provided sources do not establish current campaign activity, scale, or specific threat actors.
Researcher notes
The source evidence supports unauthenticated command injection via unsanitized ifname in stainfo.cgi. Avoid assuming all Ubiquiti products are affected; the bundle names specific firmware families and one example device, while structured affected-product data is incomplete.
Mitigation direction
- Inventory Ubiquiti wireless ISP devices and confirm firmware versions.
- Upgrade to the fixed firmware versions cited by the vendor guidance.
- Remove internet exposure from device management interfaces wherever possible.
- Restrict management access to trusted administrative networks.
- Check current Ubiquiti guidance for device-specific upgrade paths.
Validation and detection
- Identify devices matching AirOS, AirMax ISP, AirSync, or 802.11 ISP product lines.
- Compare installed firmware against v4.0.1, v5.3.5, or v5.4.5 as applicable.
- Review perimeter exposure for web management interfaces on affected devices.
- Check logs for unexpected management requests or configuration changes.
- Confirm remediated devices are no longer externally reachable for administration.

Improper Neutralization of Special Elements used in a Command ('Command Injection')
Improper Neutralization of Special Elements used in a Command ('Command Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
