Security Bulletin
This security bulletin contains information about 10 vulnerabilities.
1) Improper Authentication
EUVDB-ID: #VU23961
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-9496
CWE-ID:
CWE-287 - Improper Authentication
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to missing state validation steps when processing the
SAE confirm message when in hostapd/AP mode. A remote attacker can bypass authentication process, force the hostapd process to terminate and perform a denial of service (DoS) attack on the target system.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) 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).

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.

5) Key management errors
EUVDB-ID: #VU8837
Risk: High
CVSSv3.1: 8.6 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-13077
CWE-ID:
CWE-320 - Key Management Errors
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to force a supplicant to reinstall a previously used pairwise key.
The weakness exists in the processing of the 802.11i 4-way handshake messages of the WPA and WPA2 protocols due to ambiguities in the processing of associated protocol messages. An adjacent attacker can use man-in-the-middle techniques to retransmit previously used message exchanges between supplicant and authenticator.
