CISA KEV Advisory
Dasan GPON Routers Command Injection Vulnerability
Dasan GPON Routers contain an authentication bypass vulnerability. When combined with CVE-2018-10561, exploitation can allow an attacker to perform remote code execution.
The impacted product is end-of-life and should be disconnected if still in use.
Risk Analysis
This is an authentication bypass vulnerability in Dasan GPON Routers. When chained with another vulnerability, it can lead to remote code execution. The high EPSS score and confirmed exploitation in the wild make this a critical issue.
This vulnerability is actively exploited in the wild and is included in CISA's KEV catalog. It is remotely exploitable.
Update Dasan GPON Routers to the latest secure firmware. Implement network segmentation to limit exposure of these devices.
Technical Analysis
CVE-2018-10562 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2018-10562 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
