CVE-2011-1646: The web management interface on the Cisco RVS4000 Gigabit Security Router with software 1.x before 1.3.3.4...

Security readout for executives and security teams

CVE-2011-1646 lets a logged-in user run system commands through diagnostic tools in the Cisco router web interface. If these routers are still used, compromise of valid credentials could turn a network security device into an attacker-controlled foothold. Exposure is limited to environments still running the listed Cisco RVS4000 or WRVS4400N firmware and allowing authenticated access to the web management interface. The source bundle does not identify internet-wide prevalence or affected CPEs. Prioritize remediation if these routers remain in production, especially at network edges or remote offices. The issue requires authentication, but successful abuse gives command execution on a security router, which can affect network trust and visibility. Mitigation focus: Upgrade RVS4000 1.x to 1.3.3.4 or later.; Upgrade RVS4000 2.x to 2.0.2.7 or later.; Upgrade WRVS4400N to 2.0.2.1 or later..
