Privilege Escalation via Project File Tampering in AVEVA Process Optimization
CVE-2025-64729 is a missing authorization vulnerability in AVEVA Process Optimization affecting versions 2024.1 and earlier. According to the advisory content, an authenticated attacker with only OS Standard User privileges can tamper with Process Optimization project files and embed code into those files. If a victim user subsequently opens or otherwise interacts with the modified project files, the embedded code can execute in the victim’s security context, resulting in privilege escalation to that user’s identity. The issue is described in CISA/AVEVA material as involving insufficient authorization controls around project file handling or modification, enabling unauthorized alteration of trusted project content.
