CVE-2026-67868 is a critical heap-based out-of-bounds write vulnerability in S2OPC version 1.7.3. It occurs in the server-side EventFilter handling during CreateMonitoredItems processing. This flaw allows a remote attacker to execute arbitrary code on the affected system.
AI Analysis
Technical Summary
This vulnerability involves a heap-based out-of-bounds write in S2OPC 1.7.3 specifically during the processing of EventFilter in CreateMonitoredItems on the server side. The flaw enables remote code execution by corrupting memory, which can be exploited by an unauthenticated attacker over the network. The CVSS v3.1 base score is 9.8, indicating critical severity with network attack vector, low attack complexity, no privileges or user interaction required, and full confidentiality, integrity, and availability impact.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code on the vulnerable server, potentially leading to full system compromise including data theft, service disruption, or further network penetration.
Mitigation Recommendations
No patch or official fix information is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, consider limiting network exposure of the affected service and applying any available workarounds recommended by the vendor.
