CVE-2020-26140 5 Alfa, Arista, Cisco and 2 more 388 Awus036h, Awus036h Firmware, C-100 and 385 more 2026-06-17 3.3 LOW 6.5 MEDIUM
An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to inject arbitrary data frames independent of the network configuration.
CVE-2020-26139 5 Arista, Cisco, Debian and 2 more 330 C-100, C-100 Firmware, C-110 and 327 more 2026-06-17 2.9 LOW 5.3 MEDIUM
An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients.
CVE-2020-25686 4 Arista, Debian, Fedoraproject and 1 more 4 Eos, Debian Linux, Fedora and 1 more 2026-06-17 4.3 MEDIUM 3.7 LOW
A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for an existing pending request for the same name and forwards a new request. By default, a maximum of 150 pending queries can be sent to upstream servers, so there can be at most 150 queries for the same name. This flaw allows an off-path attacker on the network to substantially reduce the number of attempts that it would have to perform to forge a reply and have it accepted by dnsmasq. This issue is mentioned in the "Birthday Attacks" section of RFC5452. If chained with CVE-2020-25684, the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
CVE-2020-25685 4 Arista, Debian, Fedoraproject and 1 more 4 Eos, Debian Linux, Fedora and 1 more 2026-06-17 4.3 MEDIUM 3.7 LOW
A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in forward.c:reply_query(), which is the forwarded query that matches the reply, by only using a weak hash of the query name. Due to the weak hash (CRC32 when dnsmasq is compiled without DNSSEC, SHA-1 when it is) this flaw allows an off-path attacker to find several different domains all having the same hash, substantially reducing the number of attempts they would have to perform to forge a reply and get it accepted by dnsmasq. This is in contrast with RFC5452, which specifies that the query name is one of the attributes of a query that must be used to match a reply. This flaw could be abused to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25684 the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
CVE-2020-25684 4 Arista, Debian, Fedoraproject and 1 more 4 Eos, Debian Linux, Fedora and 1 more 2026-06-17 4.3 MEDIUM 3.7 LOW
A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in the forward.c:reply_query() if the reply destination address/port is used by the pending forwarded queries. However, it does not use the address/port to retrieve the exact forwarded query, substantially reducing the number of attempts an attacker on the network would have to perform to forge a reply and get it accepted by dnsmasq. This issue contrasts with RFC5452, which specifies a query's attributes that all must be used to match a reply. This flaw allows an attacker to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25685 or CVE-2020-25686, the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
CVE-2020-24588 8 Arista, Cisco, Debian and 5 more 350 C-100, C-100 Firmware, C-110 and 347 more 2026-06-17 2.9 LOW 3.5 LOW
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets.
CVE-2020-24587 6 Arista, Cisco, Debian and 3 more 332 C-100, C-100 Firmware, C-110 and 329 more 2026-06-17 1.8 LOW 2.6 LOW
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed.
CVE-2020-24586 5 Arista, Debian, Ieee and 2 more 44 C-200, C-200 Firmware, C-230 and 41 more 2026-06-17 2.9 LOW 3.5 LOW
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
CVE-2020-24360 1 Arista 27 7280cr2ak-30, 7280cr2k-60, 7280cr3-32d4 and 24 more 2026-06-17 6.1 MEDIUM 7.4 HIGH

CVE-2019-18615 1 Arista 1 Cloudvision Portal 2026-06-17 3.5 LOW 4.9 MEDIUM
In CloudVision Portal (CVP) for all releases in the 2018.2 Train, under certain conditions, the application logs user passwords in plain text for certain API calls, potentially leading to user password exposure. This only affects CVP environments where: 1. Devices have enable mode passwords which are different from the user's login password, OR 2. There are configlet builders that use the Device class and specify username and password explicitly Application logs are not accessible or visible from the CVP GUI. Application logs can only be read by authorized users with privileged access to the VM hosting the CVP application.
CVE-2019-18181 1 Arista 1 Cloudvision Portal 2026-06-17 4.6 MEDIUM 7.8 HIGH
In CloudVision Portal all releases in the 2018.1 and 2018.2 Code train allows users with read-only permissions to bypass permissions for restricted functionality via CVP API calls through the Configlet Builder modules. This vulnerability can potentially enable authenticated users with read-only access to take actions that are otherwise restricted in the GUI.
