CVE-2020-15023: Askey AP5100W Firmware

Medium severity, CVSS 5.9. EPSS: 1.6% chance of exploitation in the next 30 days.

Askey AP5100W devices through AP5100W_Dual_SIG_1.01.097 are affected by WPS PIN offline brute-force cracking. This arises because of issues with the random number selection for the Diffie-Hellman exchange. By capturing an attempted (and even failed) WPS authentication attempt, it is possible to brute force the overall authentication exchange. This allows an attacker to obtain the recovered WPS PIN in minutes or even seconds, and eventually obtain the Wi-Fi PSK key, gaining access to the Wi=Fi network.

Affected products

• Askey AP5100W Firmware: up to and including 1.01.097
