CVE-2019-1724: Cisco Small Business RV320 and RV325 Routers Session Hijacking Vulnerability

A vulnerability in the session management functionality of the web-based interface for Cisco Small Business RV320 and RV325 Dual Gigabit WAN VPN Routers could allow an unauthenticated, remote attacker to hijack a valid user session on an affected system. An attacker could use this impersonated session to create a new user account or otherwise control the device with the privileges of the hijacked session. The vulnerability is due to a lack of proper session management controls. An attacker could exploit this vulnerability by sending a crafted HTTP request to a targeted device. A successful exploit could allow the attacker to take control of an existing user session on the device. Exploitation of the vulnerability requires that an authorized user session is active and that the attacker can craft an HTTP request to impersonate that session.

Security readout for executives and security teams

Plain-English summary

This flaw lets a remote unauthenticated attacker hijack an active administrator session on Cisco RV320/RV325 routers. If successful, the attacker could create accounts or control the router with the victim session’s privileges. It requires an active authorized session, but impact is high.

Executive priority

Treat as high priority for any deployed RV320/RV325 routers, particularly internet-reachable management interfaces. The business risk is unauthorized router control, which can affect network availability, traffic confidentiality, and perimeter integrity.

Technical view

CVE-2019-1724 is a Cisco RV320/RV325 web interface session management weakness, mapped to CWE-287. Cisco describes missing proper session management controls allowing impersonation of an active valid session via a crafted HTTP request. CVSS v3.0 is 8.8 with high confidentiality, integrity, and availability impact.

Likely exposure

Organizations using Cisco Small Business RV320 or RV325 Dual Gigabit WAN VPN Routers may be exposed, especially where the web-based management interface is reachable by untrusted networks. The source bundle does not specify affected firmware versions or CPEs.

Exploitation context

The provided sources do not indicate CISA KEV listing or active exploitation. Exploitation requires an active authorized user session and attacker ability to impersonate that session through the web interface.

Researcher notes

Evidence is strong on vulnerability nature and impact, but incomplete on affected firmware versions and exact fixed releases in the provided bundle. Avoid assuming exploitation in the wild; KEV is false in the supplied data.

Mitigation direction

  • Review Cisco advisory cisco-sa-20190501-sbr-hijack for official fixed firmware or guidance.
  • Inventory Cisco RV320 and RV325 routers and prioritize management-plane exposure reduction.
  • Restrict web-based administration to trusted admin networks or VPN-only access.
  • End unnecessary administrator sessions and enforce disciplined admin logout practices.
  • Monitor Cisco advisories for version-specific remediation details if firmware status is unclear.

Validation and detection

  • Confirm whether RV320 or RV325 routers exist in the environment.
  • Identify firmware versions and compare them with Cisco’s advisory guidance.
  • Check whether web management is reachable from untrusted networks.
  • Review administrative account changes for unexpected new users.
  • Look for router management access during active administrator sessions.
