Security News > 2021 > August > Cisco: Firewall manager RCE bug is a zero-day, patch incoming
In a Thursday security advisory update, Cisco revealed that a remote code execution vulnerability in the Adaptive Security Device Manager Launcher disclosed last month is a zero-day bug that has yet to receive a security update.
Cisco ADSM is a firewall appliance manager that provides a web interface for managing Cisco Adaptive Security Appliance firewalls and AnyConnect Secure Mobility clients.
"At the time of publication, Cisco planned to fix this vulnerability in Cisco ASDM," the company says in the updated advisory.
While Cisco PSIRT said that proof-of-concept exploit code was available publicly when the bug was disclosed, it also added that there was no evidence of in the wild abuse.
Cisco revealed the zero-day in November 2020 without security updates addressing the underlying weakness, but it did provide mitigation measures to decrease the attack surface.
Last month, attackers immediately pounced on a Cisco ASA bug, immediately after Positive Technologies' Offensive Team published a PoC exploit.
