CVE-2017-16598
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThis vulnerability allows remote attackers to execute code by overwriting arbitrary files on vulnerable installations of NetGain Systems Enterprise Manager 7.2.730 build 1034. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the org.apache.jsp.u.jsp.tools.snmpwalk.snmpwalk_005fdo_jsp servlet, which listens on TCP port 8081 by default. When parsing the ip parameter, the process does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code under the context of Administrator. Was ZDI-CAN-5138.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidencePath traversal vulnerability in NetGain Enterprise Manager's snmpwalk servlet (TCP 8081) allows authenticated attackers to overwrite arbitrary files via the ip parameter without validating the supplied path, leading to remote code execution as Administrator. The authentication requirement can be bypassed.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm NetGain Enterprise Manager installationIdentify whether NetGain Enterprise Manager is installed in your environmentAffected if NetGain Enterprise Manager software is present on the system
-
Check installed versionDetermine the exact version number of the NetGain Enterprise Manager installationAffected if The installed version is 7.2.730
-
Verify snmpwalk service availabilityCheck if port 8081 is open and accepting connections on the system running NetGain Enterprise ManagerAffected if Port 8081 is accessible and responding
-
Confirm snmpwalk servlet is reachableAttempt to access the snmpwalk servlet endpoint to verify it is exposedAffected if The snmpwalk servlet is accessible via network or localhost
Your environment is affected if NetGain Enterprise Manager version 7.2.730 is installed and the snmpwalk servlet on port 8081 is reachable

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation for the ip parameter to ensure only valid IP addresses are accepted, and fix the authentication bypass mechanism. Consider network segmentation to restrict access to port 8081.
