What is CVE-2023-40459?

The ACEManager component in ALEOS versions 4.16 and earlier fails to adequately sanitize input during the authentication process. This flaw could potentially lead to a Denial of Service (DoS) condition for ACEManager, effectively disrupting access to services managed by this component without affecting the overall functionality of the router. Notably, ACEManager can recover from such a DoS condition by performing a restart within roughly ten seconds after the incident, allowing for a temporary service interruption.

Affected Version(s)

ALEOS 4.10 <= 4.16

ALEOS 0 <= 4.9.8

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
