Description

A stack-based buffer overflow vulnerability exists in the OpenPLC Runtime EtherNet/IP parser functionality of OpenPLC _v3 b4702061dc14d1024856f71b4543298d77007b88. A specially crafted EtherNet/IP request can lead to remote code execution. An attacker can send a series of EtherNet/IP requests to trigger this vulnerability.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
