Technical details
The vulnerability is classified as improper information exposure through debug symbols left in firmware binaries (CWE-1104/CWE-11). An unauthenticated attacker can obtain the publicly available firmware update files and extract debugging symbols from compiled binaries, significantly reducing the complexity and time required for reverse engineering. Debug symbols provide function names, variable names, and source-level structure information that facilitate vulnerability research. The attack requires only file-system access to the firmware package—no authentication or network connectivity is needed. Patches were released in V2.70 and later versions.
