Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2020-24586)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the 802.11 standard due to the affected device does not clear its cache/memory to remove fragments of an incomplete MSDU/MMPDU from previous session after reconnection/reassociation. A remote attacker on the local network can perform a fragment cache attack and perform a denial of service (DoS) attack.
2) Information disclosure (CVE-ID: CVE-2020-24587)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in Windows Wireless Networking. A remote attacker on the local network can gain unauthorized access to sensitive information on the system.
3) Spoofing attack (CVE-ID: CVE-2020-24588)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data in Windows Wireless Networking. A remote attacker on the local network can spoof page content.
4) Input validation error (CVE-ID: CVE-2020-26139)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to forwarding EAPOL frames even though the sender is not yet authenticated. A remote attacker on the local network can cause a denial of service (DoS) condition on the target system.
5) Input validation error (CVE-ID: CVE-2020-26140)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. A remote attacker on the local network can inject arbitrary data frames independent of the network configuration.
6) Input validation error (CVE-ID: CVE-2020-26141)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the Wi-Fi implementation does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. A remote attacker on the local network can inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-confidentiality protocol.
7) Input validation error (CVE-ID: CVE-2020-26142)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. A remote attacker on the local network can inject arbitrary network packets, independent of the network configuration.
8) Input validation error (CVE-ID: CVE-2020-26143)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the WEP, WPA, WPA2, and WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. A remote attacker on the local network can inject arbitrary data frames independent of the network configuration.
9) Spoofing attack (CVE-ID: CVE-2020-26144)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data in Windows Wireless Networking. A remote attacker on the local network can spoof page content.
10) Input validation error (CVE-ID: CVE-2020-26145)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the WEP, WPA, WPA2, and WPA3 implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process them as full unfragmented frames. A remote attacker on the local network can inject arbitrary network packets independent of the network configuration.
11) Input validation error (CVE-ID: CVE-2020-26146)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the WPA, WPA2, and WPA3 implementations reassemble fragments with non-consecutive packet numbers. A remote attacker on the local network can exfiltrate selected fragments.
12) Input validation error (CVE-ID: CVE-2020-26147)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. A remote attacker on the local network can inject packets and/or exfiltrate selected fragments
