Last modified Jun 17, 2026

CVE-2023-33220 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. During the retrofit validation process, the firmware doesn't properly check the boundaries while copying some attributes to check. This allows a stack-based buffer overflow that could lead to a potential Remote Code Execution on the targeted device . EPSS estimates a 1.14% chance of exploitation in the next 30 days.
