CVE-2018-25360 Agatasoft CVE debrief

AgataSoft Auto PingMaster 1.5 contains a stack-based buffer overflow vulnerability in the Trace Route host name field. The vulnerability allows local attackers to execute arbitrary code by triggering structured exception handling (SEH). Attackers can craft a malicious ping.txt file containing shellcode and jump instructions that overwrite the SEH handler pointer, achieving code execution when the file contents are pasted into the application. The vulnerability is classified as CWE-121 (Stack-based Buffer Overflow) and carries a CVSS 4.0 score of 8.6 (HIGH severity). The attack vector is local with low attack complexity, requiring no privileges or user interaction. The vulnerability impacts confidentiality, integrity, and availability with high severity. The CVE was published on 2026-05-25 and last modified on 2026-05-26. The vulnerability status in NVD is currently marked as Deferred.

Who should care

Organizations running AgataSoft Auto PingMaster 1.5 on Windows endpoints; security teams managing legacy network diagnostic tools; incident responders investigating potential local privilege escalation or code execution on workstations with network monitoring software installed.

Technical summary

A stack-based buffer overflow exists in AgataSoft Auto PingMaster 1.5's Trace Route host name field. The vulnerability can be exploited by crafting a malicious ping.txt file with shellcode and jump instructions that overwrite the SEH handler pointer. When this content is pasted into the application, the corrupted SEH handler enables arbitrary code execution. The vulnerability requires local access but no privileges or user interaction, resulting in complete compromise of confidentiality, integrity, and availability on affected systems.

Defensive priority

HIGH

Recommended defensive actions

  • Remove or disable AgataSoft Auto PingMaster 1.5 from all systems due to unpatched stack-based buffer overflow vulnerability
  • Restrict local access to systems where Auto PingMaster 1.5 must remain installed
  • Implement application whitelisting to prevent execution of unauthorized programs that could leverage this vulnerability
  • Monitor for suspicious ping.txt files or unexpected pasting operations into Auto PingMaster
  • Consider network segmentation to limit lateral movement if local code execution occurs
  • Review system logs for anomalous SEH-based exception handling patterns
