Technical Analysis

The KAON PG5298A and PG5298B routers contain a vulnerability caused by incorrect authorization controls in their firmware. Authenticated users can exploit this flaw by sending specially crafted JSON-RPC requests, enabling them to perform operations beyond those allowed via the graphical user interface, including reading system files and executing commands. This vulnerability is identified as CWE-863 and has a CVSS 4.0 score of 8.5, indicating high severity. 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 restrictions to perform sensitive operations such as reading system files and executing commands on affected KAON PG5298A and PG5298B routers. This could lead to unauthorized system control or data exposure.

Mitigation Recommendations

Upgrade affected devices to firmware version 3.0.82 for PG5298A and 4.0.82 for PG5298B or later, where this vulnerability has been fixed. No other mitigation guidance is provided.
