CISA KEV Advisory
Cisco Small Business Routers Improper Input Validation Vulnerability
A vulnerability in the web-based management interface of Cisco Small Business RV320 and RV325 Dual Gigabit WAN VPN Routers could allow an authenticated, remote attacker with administrative privileges on an affected device to execute arbitrary commands.
Apply updates per vendor instructions.
Risk Analysis
A vulnerability in the web-based management interface of Cisco Small Business RV320 and RV325 Dual Gigabit WAN VPN Routers allows an authenticated, remote attacker with administrative privileges to execute arbitrary commands. The high EPSS score of 0.93023 indicates a strong likelihood of exploitation, and its inclusion in CISA's KEV catalog confirms it is actively being exploited. This is a critical concern for administrators of these devices.
This vulnerability is actively exploited in the wild, indicating an immediate threat to affected Cisco RV320 and RV325 routers. While requiring authentication, the flaw is remotely exploitable once an attacker gains administrative credentials.
Apply the latest security updates and patches from Cisco for the RV320 and RV325 routers. Ensure strong, unique passwords are used for administrative accounts and restrict access to the web-based management interface to trusted internal networks only.
Technical Analysis
CVE-2019-1652 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-2019-1652 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.
