CVSS: 5.4EPSS: 0%CPEs: 20EXPL: 0CVE-2020-26147 – kernel: reassembling mixed encrypted/plaintext fragments
https://notcve.org/view.php?id=CVE-2020-26147
An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. Se detectó un problema en el kernel de Linux versión 5.8.9. Las implementaciones de WEP, WPA, WPA2 y WPA3 reensamblan fragmentos aunque algunos de ellos se enviaron en texto plano. • http://www.openwall.com/lists/oss-security/2021/05/11/12 https://cert-portal.siemens.com/productcert/pdf/ssa-913875.pdf https://github.com/vanhoefm/fragattacks/blob/master/SUMMARY.md https://lists.debian.org/debian-lts-announce/2021/06/msg00019.html https://lists.debian.org/debian-lts-announce/2021/06/msg00020.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wifi-faf-22epcEWu https://www.arista.com/en/support/advisories-notices/security-advisories/12602-s • CWE-307: Improper Restriction of Excessive Authentication Attempts •

https://notcve.org/view.php?id=CVE-2020-26146
An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WPA, WPA2, and WPA3 implementations reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. Note that WEP is vulnerable to this attack by design. • http://www.openwall.com/lists/oss-security/2021/05/11/12 https://cert-portal.siemens.com/productcert/pdf/ssa-913875.pdf https://github.com/vanhoefm/fragattacks/blob/master/SUMMARY.md https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wifi-faf-22epcEWu https://www.arista.com/en/support/advisories-notices/security-advisories/12602-security-advisory-63 https://www.fragattacks.com https://access.redhat.com/security/cve/CVE-2020-26146 https://bugzilla.redhat.com/show&# • CWE-20: Improper Input Validation CWE-307: Improper Restriction of Excessive Authentication Attempts •
CVSS: 5.3EPSS: 0%CPEs: 330EXPL: 0CVE-2020-26139 – kernel: Forwarding EAPOL from unauthenticated wifi client
https://notcve.org/view.php?id=CVE-2020-26139
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. Se detectó un problema en el kernel en NetBSD versión 7.1. Un punto de acceso (AP) reenvía tramas EAPOL a otros clientes aunque el remitente aún no se haya autenticado con éxito en el AP. • http://www.openwall.com/lists/oss-security/2021/05/11/12 https://cert-portal.siemens.com/productcert/pdf/ssa-913875.pdf https://github.com/vanhoefm/fragattacks/blob/master/SUMMARY.md https://lists.debian.org/debian-lts-announce/2021/06/msg00019.html https://lists.debian.org/debian-lts-announce/2021/06/msg00020.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wifi-faf-22epcEWu https://www.arista.com/en/support/advisories-notices/security-advisories/12602-s • CWE-287: Improper Authentication CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
