CISA KEV Advisory
D-Link DIR-820 Router OS Command Injection Vulnerability
D-Link DIR-820 routers contain an OS command injection vulnerability that allows a remote, unauthenticated attacker to escalate privileges to root via a crafted payload with the ping_addr parameter to ping.ccp.
The impacted product is end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue utilization of the product.
Risk Analysis
This OS command injection vulnerability in D-Link DIR-820 routers allows a remote, unauthenticated attacker to escalate privileges to root. Rated as HIGH severity with a very high EPSS score, this indicates a significant likelihood of exploitation. Its presence in CISA's KEV confirms it has been actively exploited.
This vulnerability has been actively exploited in the wild and is part of CISA's KEV, confirming its use in real-world attacks. It is remotely exploitable by an unauthenticated attacker via a crafted ping_addr parameter.
Users should update their D-Link DIR-820 routers to the latest firmware provided by the vendor. Restricting access to the router's web interface from the internet is also recommended.
Technical Analysis
CVE-2023-25280 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-2023-25280 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.
