Successful exploitation could allow an attacker to execute arbitrary code as a privileged user on the underlying operating system leading to complete system compromise.\n\n## Affected\n\n- `arubaos_aos >= 8.13.0.0 <= 8.13.3.0`\n- `arubaos_aos >= 8.10.0.0 <= 8.10.0.23`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":45,"depthScoreParts":{"impact":44.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
