Summary
Multiple Vulnerabilities in Frame Aggregation and Fragmentation Implementations of 802.11 Specification Affecting Cisco Products: May 2021
Notes
Summary
On May 11, 2021, the research paper Fragment and Forge: Breaking Wi-Fi Through Frame Aggregation and Fragmentation was made public. This paper discusses 12 vulnerabilities in the 802.11 standard. One vulnerability is in the frame aggregation functionality, two vulnerabilities are in the frame fragmentation functionality, and the other nine are implementation vulnerabilities. These vulnerabilities could allow an attacker to forge encrypted frames, which could in turn enable the exfiltration of sensitive data from a targeted device.
This advisory will be updated as additional information becomes available.

Bei der Fragmentierungsfunktion f\u00fcr 802.11-Frames fehlen \u00dcberpr\u00fcfungen, was mitunter zur Entgegennahme von unverschl\u00fcsselten Frames oder Fragmenten f\u00fchrt. Au\u00dferdem gibt es bei EAPoL (Extensible Authentication Protocol over Local Area Network) und TKIP (Temporal Key Integrity Protocol) mehrere produktspezifische Implementierungsfehler. Ein Angreifer innerhalb der WiFi-Funkreichweite kann diese Schwachstellen ausnutzen, um beliebigen Datenverkehr in ein drahtloses Netzwerk zu injizieren und Daten zu exfiltrieren. Zu den praktischen Angriffen geh\u00f6ren verschiedene Arten von Man-in-the-Middle-Angriffen (um die Ausnutzung anderer Schwachstellen zu erm\u00f6glichen), DNS Poisoning (z. B. um Phishing zu erm\u00f6glichen) und die Offenlegung von Daten aus ungesch\u00fctzter Kommunikation." } ], "product_status": { "known_affected": [ "2070", "T006498", "T010954", "132177", "67646", "4035", "T005205", "T012215", "T004914", "T019358", "697", "T019316", "T019338", "T018746", "398363", "T000052", "T008011", "T000491", "T006520", "T015978", "T016605", "6368", "T015357", "T016423", "T016785", "T019302", "T019304", "T019303", "2951", "T002207", "T019305", "T000126", "7107", "T002543", "T009493" ] }, "release_date": "2021-05-11T22:00:00Z", "title": "CVE-2020-26147" } ] }

Details
An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets, independent of the network configuration.
