CVE-2024-6435 Rockwell Automation CVE debrief

Who should care

Organizations operating Rockwell Automation Pavilion 8 in industrial environments, particularly those in critical infrastructure sectors. Security teams responsible for OT/ICS asset management, identity and access management administrators, and compliance officers monitoring NIST CSF or IEC 62443 adherence should prioritize this vulnerability due to its potential for unauthorized administrative access in process control environments.

Technical summary

CVE-2024-6435 is a privilege escalation vulnerability in Rockwell Automation Pavilion 8 versions 5.15.00 through 5.20.00. The flaw allows authenticated users with basic privileges to access administrative functions that should require elevated privileges. Successful exploitation enables attackers to create users with elevated privileges and read sensitive information from the 'views' section. The vulnerability has a CVSS 3.1 score of 8.8 (HIGH severity) with network attack vector, low attack complexity, and low privilege requirements. Rockwell Automation has released version 6.0 to address this issue. CISA recommends upgrading immediately or applying compensating controls including access restriction and privilege review procedures.
