CVE-2016-1391: Cisco Prime Network Analysis Module (NAM) before 6.1(1) patch.6.1-2-final and 6.2.x before 6.2(2) and Prime...

Security readout for executives and security teams

CVE-2016-1391 lets a logged-in remote user run operating system commands through crafted HTTP requests against vulnerable Cisco Prime NAM or vNAM systems. The main concern is that a compromised or misused account could become system-level control of a network monitoring appliance. Exposure is limited to organizations running Cisco Prime NAM or vNAM in the affected version ranges. The attacker needs authenticated access, so internet exposure matters less than who can reach and log into the web interface. Treat this as a high-priority legacy appliance remediation if NAM or vNAM is still deployed. Authenticated command execution can turn a monitoring system into a foothold inside the network. Mitigation focus: Upgrade affected Cisco Prime NAM and vNAM systems to the fixed releases named by Cisco.; Check Cisco's advisory for exact fixed-release and upgrade guidance.; Restrict web management access to trusted administrative networks..
