Version(s): 12.1X46; SRX 210, 240, 650 series (with AX411 Wireless Access Points)
Description:   Multiple vulnerabilities were reported in Juniper Junos. A remote user on the wireless network can access and modify data on the wireless network.

A remote user within range of the wireless network can record and replay retransmissions of part of the 802.11i 4-way handshake of the WPA and WPA2 protocols to force a reinstallation of the pairwise transient key, a group key, or an integrity key and force a reset of the incremental transmit packet number nonce and the receive replay counter. As a result, the remote user can replay encrypted packets, decrypt packets, and forge packets.

A remote user on the wireless network can reinstall the pairwise encryption key (PTK-TK) [CVE-2017-13077].

A remote user on the wireless network can reinstall the group key (GTK) [CVE-2017-13078, CVE-2017-13080].

A remote user on the wireless network can reinstall the integrity group key (IGTK) [CVE-2017-13079, CVE-2017-13081].

A remote user on the wireless network can reinstall the STK key in the PeerKey handshake [CVE-2017-13084].

A remote user on the wireless network can reinstall the Tunneled Direct-Link Setup (TDLS) PeerKey (TPK) key in the TDLS handshake [CVE-2017-13086].

A remote user on the wireless network can reinstall the group key (GTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame [CVE-2017-13087].

A remote user on the wireless network can reinstall the integrity group key (IGTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame [CVE-2017-13088].

The vendor has assigned PR 1297300 to these vulnerabilities.

This set of vulnerabilities is referred to as KRACK (Key Reinstallation AttaCK).
