Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Use of a broken or risky cryptographic algorithm
EUVDB-ID: #VU59838
Risk: Low
CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-23304
CWE-ID:
CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
Exploit availability: No
DescriptionThe 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).
Install updates from vendor's repository.

4) Information disclosure
EUVDB-ID: #VU23959
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-9494
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the implementations of SAE are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. A remote attacker can gain leaked information from a side channel attack that can be used for full password recovery.
