CVE-2018-25369 scanwith CVE debrief

CVE-2018-25369 documents a buffer overflow vulnerability in Visual Ping 0.8.0.0, a Windows-based ping utility. The flaw exists in the application's input field handling for configuration parameters including Host, Time Out, Packet Size, Pause, and Loops. Supplying data exceeding 4108 bytes to any of these fields triggers a buffer overflow, resulting in application crash and denial of service. The vulnerability requires local access to the application interface, with no authentication prerequisites. The CVSS 4.0 vector indicates local attack vector with high availability impact but no confidentiality or integrity impact. The weakness is categorized as CWE-120 (Buffer Copy without Checking Size of Input). The CVE was published on May 25, 2026 and modified on May 26, 2026, with NVD status currently marked as Deferred. Multiple source references including VulnCheck advisory and Exploit-DB entry provide technical disclosure details.

Who should care

System administrators managing Windows endpoint environments, security teams monitoring for denial-of-service conditions in network diagnostic tools, and organizations with software asset management responsibilities for legacy utilities

Technical summary

Visual Ping 0.8.0.0 fails to properly validate input length in multiple configuration fields. The Host, Time Out, Packet Size, Pause, and Loops input fields accept data without adequate bounds checking. Payloads exceeding 4108 bytes trigger memory corruption and application termination. The vulnerability is exploitable only through local interaction with the application GUI, requiring no user privileges but also granting no elevated access upon exploitation. The attack results in availability impact only, with no code execution or information disclosure capabilities demonstrated.

Defensive priority

Recommended defensive actions

  • Audit endpoints for Visual Ping 0.8.0.0 installations and remove or restrict access where unnecessary
  • Implement application whitelisting to prevent unauthorized execution of Visual Ping
  • Monitor for unexpected process crashes of Visual Ping that may indicate exploitation attempts
  • Contact software distributor for patch availability given deferred NVD status
  • Consider network segmentation for systems requiring Visual Ping to limit lateral movement
  • Review and enforce input validation policies for all locally-installed utilities

Evidence notes

Evidence sources include NVD modified feed, VulnCheck advisory, and Exploit-DB reference. Vendor identification remains uncertain with 'Unknown Vendor' classification and low confidence due to limited authoritative vendor documentation. The 'Itlights' domain reference suggests possible vendor association but requires verification.

Official resources

The vulnerability was disclosed through coordinated disclosure channels with advisory publication by VulnCheck and entry in the Exploit-DB database. The NVD record reflects deferred status, indicating ongoing analysis or vendor coordination
