Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Improper Authentication (CVE-ID: CVE-2019-9496)
The 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.
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) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2022-23303)
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).4) Information disclosure (CVE-ID: CVE-2019-9494)
The 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 (CVE-ID: CVE-2017-13077)
The 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.
6) Key management errors (CVE-ID: CVE-2017-13078)
The vulnerability allows an adjacent attacker to force a supplicant to reinstall a previously used group 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.
7) Key management errors (CVE-ID: CVE-2017-13079)
The vulnerability allows an adjacent attacker to force a supplicant to reinstall a previously used integrity group 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.
8) Key management errors (CVE-ID: CVE-2017-13080)
The vulnerability allows an adjacent attacker to force a supplicant to reinstall a previously used group 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.
The vulnerability is dubbed "KRACK" attack.
9) Key management errors (CVE-ID: CVE-2017-13081)
The vulnerability allows an adjacent attacker to force a supplicant to reinstall a previously used integrity group 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.
10) Key management errors (CVE-ID: CVE-2017-13082)
The 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.
