Aditya K. Sood discovered the vulnerabilities and presented them at DefCon 2015 in Las Vegas.

He reported these vulnerabilities to ICS-CERT a few days before his presentation so the vendor was aware of the issue but has not had time to address it. ICS CERT notified the affected vendor of the report and has asked it to confirm the vulnerabilities and identify mitigations. ICS-CERT is issuing this alert to provide early notice of the report and identify baseline mitigations for reducing risks.

• Client-side encrypted password, which could lead to unauthorized access to the device
• Weakly hashed password contained in the HTTP cookie, which could lead to unauthorized access to the device

All vulnerabilities, except the client-side encrypted password, are remotely exploitable.
