This 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.

Exploit prediction

4.12% chance of exploitation in the next 30 days, higher than 90% of all scored CVEs (FIRST EPSS, 2026-11-09).
