Firmware in KAON PG5298A and PG5298B routers allow an authenticated user to send crafted JSON-RPC requests and perform operations not possible via GUI, e.g. system file read or command execution. This vulnerability has been fixed in firmware version: 3.0.82 for PG5298A and 4.0.82 for PG5298B.
CVE-2025-63080
This high-severity CVE scores 8.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 73% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
