Note, this vulnerability exists due to incomplete fix for #VU23959 (CVE-2019-9494).

2) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-23304)

The vulnerability allows a remote attacker to gain access to sensitive information on the target system.

The vulnerability exists due to the implementations of EAP-PWD are vulnerable to side-channel attacks as a result of cache access patterns. A remote attacker with ability to install and execute applications can crack weak passwords when memory access patterns are visible in a shared cache.

Note, this vulnerability exists due to incomplete fix for #VU23960 (CVE-2019-9495).

3) Insecure DLL loading (CVE-ID: CVE-2022-2334)

The vulnerability allows a remote user to compromise vulnerable system.

The vulnerability exists due to the application searches for a library dll that is not found. A remote administrator can place a specially crafted .dll file and execute arbitrary code on target system.
