SYN Flood or FIN Flood attack in ECos 1 and other versions embedded devices results in web Authentication Bypass. "eCos Embedded Web Servers used by Multiple Routers and Home devices, while sending SYN Flood or FIN Flood packets fails to validate and handle the packets and does not ask for any sign of authentication resulting in Authentication Bypass. An attacker can take complete advantage of this bug and take over the device remotely or locally. The bug has been successfully tested and reproduced in some versions of SOHO Routers manufactured by TOTOLINK, GREATEK and others."

Protection Mechanism Failure in ECOS Secure Boot Stick (aka SBS) 5.6.5 allows a local attacker to duplicate an authentication factor via cloning.

Protection Mechanism Failure in ECOS Secure Boot Stick (aka SBS) 5.6.5 allows an attacker to compromise authentication and encryption keys via compromised firmware.

Authentication Bypass by Spoofing vulnerability in ECOS System Management Appliance (aka SMA) 5.2.68 allows a man-in-the-middle attacker to compromise authentication keys and configurations via IP spoofing during "Easy Enrollment."

Incomplete Cleanup vulnerability in ECOS Secure Boot Stick (aka SBS) 5.6.5 allows an attacker to compromise authentication and encryption keys via a compromised host PC after a reset.

Insufficient Verification of Data Authenticity vulnerability in ECOS Secure Boot Stick (aka SBS) 5.6.5 allows an attacker to manipulate security relevant configurations and execute malicious code.

Protection Mechanism Failure in ECOS Secure Boot Stick (aka SBS) 5.6.5 allows an attacker to compromise authentication and encryption keys via a virtualization attack.

Incorrect access control in ECOS System Management Appliance (aka SMA) 5.2.68 allows a user to compromise authentication keys, and access and manipulate security relevant configurations, via unrestricted database access during Easy Enrollment.

Undocumented Factory Backdoor in ECOS Secure Boot Stick (aka SBS) 5.6.5 allows the vendor to extract confidential information via remote root SSH access.
