Descriptions

Improper Input Validation vulnerability allows Remote Code Execution. Affected products: ABB ASPECT - Enterprise v3.08.02; NEXUS Series v3.08.02; MATRIX Series v3.08.02

ABB Cylon Aspect version 3.08.02 is vulnerable to code execution and sudo misconfiguration flaws. An authenticated remote code execution vulnerability in the firmware update mechanism allows an attacker with valid credentials to escalate privileges and execute commands as root. The process involves uploading a crafted .aam file through fileSystemUpdate.php, which is then moved to /tmp and executed by fileSystemUpdateExecute.php. This script leverages sudo to run the upgrade-bundle.sh script, enabling the attacker to bypass input validation checks and execute arbitrary code, leading to full system compromise and unauthorized root access.
