CVE-2023-40462 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The ACEManager component of ALEOS 4.16 and earlier does not perform input sanitization during authentication, which could potentially result in a Denial of Service (DoS) condition for ACEManager without impairing other router functions. ACEManager recovers from the DoS condition by restarting within ten seconds of becoming unavailable.. EPSS estimates a 0.88% chance of exploitation in the next 30 days.
