CVE-2018-25214 Overview
CVE-2018-25214 is a local buffer overflow vulnerability in Magnetosoft MegaPing 1.0. The flaw resides in the Finger function, specifically in the Destination Address List input field. A local attacker can paste an oversized payload into the field and trigger the Start button to crash the application. The condition results in a denial of service against the running MegaPing process. The vulnerability is classified under CWE-787 (Out-of-bounds Write) and requires local access with no special privileges or user interaction beyond launching the affected functionality.
Critical Impact
Local attackers can crash the MegaPing application by submitting an oversized payload to the Destination Address List in the Finger function, producing a denial of service.
Affected Products
- Magnetosoft MegaPing 1.0
- Windows installations deployed via megaping_setup.exe
- Environments using MegaPing's Finger network diagnostic feature

Technical Details for CVE-2018-25214
Vulnerability Analysis
MegaPing is a Windows network diagnostic utility that includes Finger, Ping, Traceroute, and similar tools. The Finger function accepts user-supplied input through the Destination Address List field. The application fails to validate the length of data placed in this field before processing it. When an oversized buffer is submitted and the Start button is clicked, the application performs an out-of-bounds write that corrupts process memory and terminates the program. The issue is local in scope because exploitation requires direct interaction with the MegaPing graphical interface. Additional context is available in the VulnCheck Advisory for MegaPing and Exploit-DB entry #46004.
Root Cause
The root cause is missing bounds checking on the Destination Address List input in the Finger function. The application copies attacker-controlled input into a fixed-size buffer without enforcing a maximum length. This results in memory corruption consistent with CWE-787.
Attack Vector
An attacker with local access pastes a crafted, oversized string into the Destination Address List field within the MegaPing Finger module. Selecting Start triggers processing of the malformed input, which writes past the destination buffer boundary and crashes the process. No authentication credentials or remote network access are required. Code execution has not been demonstrated for this issue, which is currently characterized as a denial of service condition.
No verified exploit code is reproduced here. Refer to the Exploit-DB entry #46004 for the original proof-of-concept payload structure.
Detection Methods for CVE-2018-25214
Indicators of Compromise
- Unexpected termination or crash dumps generated by megaping.exe on Windows hosts
- Windows Error Reporting (WER) entries referencing MegaPing with access violation exception codes such as 0xC0000005
- Application Event Log entries indicating MegaPing faulted shortly after user interaction with the Finger feature
Detection Strategies
- Inventory endpoints for installations of Magnetosoft MegaPing 1.0 and flag any presence of the vulnerable build
- Monitor for process crashes of megaping.exe correlated with interactive user sessions
- Review WER and application crash telemetry for repeated faults tied to the Finger function
Monitoring Recommendations
- Centralize Windows application crash logs in a SIEM and alert on faults involving megaping.exe
- Track installation of unmanaged network diagnostic tools through software inventory controls
- Correlate process termination events with user login context to identify suspicious local activity
How to Mitigate CVE-2018-25214
Immediate Actions Required
- Remove Magnetosoft MegaPing 1.0 from production endpoints where it is not required
- Restrict interactive logon to MegaPing hosts to trusted administrative users only
- Replace MegaPing with maintained network diagnostic tooling that receives security updates
Patch Information
No vendor patch has been published for this issue in the referenced advisories. The Magnetosoft Official Website and VulnCheck Advisory for MegaPing do not list a corrected version at this time. Organizations should treat MegaPing 1.0 as unpatched and plan for removal or replacement.
Workarounds
- Uninstall MegaPing 1.0 on systems where the Finger function is not operationally required
- Apply application allowlisting to prevent unauthorized execution of megaping.exe
- Limit local user privileges so that only vetted personnel can launch the application interactively
# Configuration example: remove MegaPing using Windows package management
wmic product where "name like 'MegaPing%%'" call uninstall /nointeractive
