Summary

CVE-2010-5330 is a critical-severity Command Injection (CWE-77) vulnerability in Ui Airos. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2010-5330 is a command injection vulnerability affecting certain Ubiquiti devices running Air OS, including the Nanostation5. The flaw resides in stainfo.cgi (Show AP info), where the ifname variable is not sanitized before being passed to a system command, allowing shell metacharacters in an unauthenticated GET request.

An attacker with network access can send a crafted HTTP GET request to the affected endpoint and execute arbitrary commands on the device. Successful exploitation grants full control over the device, enabling actions such as configuration changes, data exfiltration, or use of the device as a pivot point, consistent with the CVSS 9.8 rating and CWE-77 classification.

Ubiquiti community advisories and firmware release notes direct users to apply the fixed versions v4.0.1 for 802.11 ISP products, v5.3.5 for AirMax ISP products, or v5.4.5 for AirSync firmware to eliminate the injection vector.

The vulnerability appears in the CISA Known Exploited Vulnerabilities catalog and has publicly available exploit code on Exploit-DB, indicating confirmed real-world exploitation.

Vulnerability Data

On certain Ubiquiti devices, Command Injection exists via a GET request to stainfo.cgi (aka Show AP info) because the ifname variable is not sanitized, as demonstrated by shell metacharacters. The fixed version is v4.0.1 for 802.11 ISP products, v5.3.5 for…

Secure development life cycle mandates input validation and command construction practices that directly prevent command injection.

prevents

Application security requirements explicitly call for controls against injection flaws including command injection.

prevents

Secure architecture principles reduce the attack surface but do not prescribe the specific neutralization techniques needed.

none

Environment separation limits the blast radius of an exploited command injection but does not prevent the flaw itself.
