Security News > 2021 > June > Cisco security devices targeted with CVE-2020-3580 PoC exploit

Attackers and bug hunters are leveraging an exploit for CVE-2020-3580 to compromise vulnerable security devices running Cisco ASA or FTD software.
Active attacks apparently started after Positive Technologies researchers shared proof-of-concept exploit code last Thursday via Twitter.
In April 2021, Cisco released new software updates because the fix for CVE-2020-3581 was incomplete.
Nine months have passed since CVE-2020-3580 was fixed, and Positive Technologies researchers were apparently confident that enough organizations have implemented the security updates and that releasing the PoC exploit code would not be widely damaging.
According to Tenable, attackers have started actively exploiting CVE-2020-3580 in the wild.
Cisco's updated security advisory can serve as a guide.
