CISA KEV Advisory
Pi-Hole AdminLTE Remote Code Execution Vulnerability
Pi-hole Web v4.3.2 (aka AdminLTE) allows Remote Code Execution by privileged dashboard users via a crafted DHCP static lease.
Apply updates per vendor instructions.
Risk Analysis
Pi-hole Web v4.3.2 (AdminLTE) is vulnerable to remote code execution by privileged dashboard users via a crafted DHCP static lease. This high-severity flaw has a very high exploitation likelihood (EPSS 0.90775). Its inclusion in CISA's KEV confirms active exploitation, making it an urgent concern.
This vulnerability is actively exploited in the wild. While requiring privileged dashboard access, it allows for remote code execution, indicating a significant risk once an attacker gains initial access.
Update Pi-hole Web to a patched version to mitigate this remote code execution vulnerability. Ensure that only trusted and authorized users have privileged access to the Pi-hole dashboard.
Technical Analysis
CVE-2020-8816 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-2020-8816 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.
