CVE-2023-40462: Debian Linux

High severity, CVSS 7.5. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 10.0 only
• Sierra Wireless ALEOS: up to and including 4.16.0
