AI Analysis
Technical Summary
The KAON PG5298A and PG5298B routers have a firmware vulnerability identified as CVE-2025-63080, classified under CWE-863 (Incorrect Authorization). Authenticated users can exploit this flaw by sending specially crafted JSON-RPC requests, enabling them to perform actions beyond the capabilities of the router's GUI, including reading system files and executing commands. This represents a significant authorization bypass. The issue has been addressed in firmware versions 3.0.82 for PG5298A and 4.0.82 for PG5298B.
Potential Impact
An authenticated user can bypass intended authorization controls to perform unauthorized system-level operations such as reading sensitive files or executing arbitrary commands on the affected routers. This could lead to compromise of the device and potentially the network it serves.
Mitigation Recommendations
A fix is available in firmware version 3.0.82 for PG5298A and 4.0.82 for PG5298B. Users should upgrade to these versions or later to remediate this vulnerability. No additional mitigation guidance is provided.
