New Critical Zero-Day Vulnerability Affects Web UI of Cisco IOS XE Software & Allows Attackers to Compromise Routers
2023-10-18 09:00

Cisco Talos discovered a new critical zero-day vulnerability in the Web User Interface feature of Cisco IOS XE software that's currently being used in the wild.

The vulnerability used to access the system and create those accounts is CVE-2023-20198; it received the highest Common Vulnerability Scoring System score of 10.

How to mitigate this Cisco IOS XE software security threat.

Only Cisco IOS XE software can be targeted by this vulnerability exploitation.

For organizations using that software, Cisco strongly recommends disabling the HTTP server feature on all internet-facing systems so the Web UI is no longer accessible.

Log files should be checked carefully for every user accessing the web UI. In addition, in the findings reported by Cisco Talos, an attacker could exploit a vulnerability patched since 2021 for further compromise.
