Description

This security bulletin contains information about 3 vulnerabilities.


1) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-23303)

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to the implementations of SAE 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 #VU23959 (CVE-2019-9494).

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

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


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)

CWE-ID: CWE-427 - Uncontrolled Search Path Element

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Clear


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.
