CVSS: 5.3EPSS: 0%CPEs: 38EXPL: 0CVE-2020-26146 – kernel: reassembling encrypted fragments with non-consecutive packet numbers
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: 6.5EPSS: 0%CPEs: 26EXPL: 0CVE-2020-26145 – kernel: accepting plaintext broadcast fragments as full frames
https://notcve.org/view.php?id=CVE-2020-26145
An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. 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. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. Se detectó un problema en los dispositivos Samsung Galaxy S3 i9305 versión 4.4.4. Las implementaciones de WEP, WPA, WPA2 y WPA3 aceptan segundos fragmentos de transmisión (o posteriores) incluso cuando se envían en texto plano y los procesan como tramas completas no fragmentados. • 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://www.fragattacks.com https://access.redhat.com/security/cve/CVE-2020-26145 https://bugzilla.redhat.com/show_bug.cgi?id=1960500 • CWE-20: Improper Input Validation CWE-307: Improper Restriction of Excessive Authentication Attempts •
CVSS: 6.5EPSS: 0%CPEs: 36EXPL: 0CVE-2020-26144 – kernel: accepting unencrypted A-MSDU frames that start with RFC1042 header
https://notcve.org/view.php?id=CVE-2020-26144
An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext A-MSDU frames as long as the first 8 bytes correspond to a valid RFC1042 (i.e., LLC/SNAP) header for EAPOL. An adversary can abuse this to inject arbitrary network packets independent of the network configuration. Se detectó un problema en los dispositivos Samsung Galaxy S3 i9305 versión 4.4.4. Las implementaciones WEP, WPA, WPA2 y WPA3 aceptan tramas A-MSDU de texto plano siempre que los primeros 8 bytes correspondan a un encabezado RFC1042 válido (es decir, LLC/SNAP) para EAPOL. • 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-2020-26144 https://bugzilla.redhat.com/show&# • CWE-20: Improper Input Validation CWE-290: Authentication Bypass by Spoofing •
