VAR-201312-0287
Vulnerability from variot - Updated: 2023-12-18 13:57The VTY authentication implementation in Cisco IOS XE 03.02.xxSE and 03.03.xxSE incorrectly relies on the Linux-IOS internal-network configuration, which allows remote attackers to bypass authentication by leveraging access to a 192.168.x.2 source IP address, aka Bug ID CSCuj90227. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. Cisco IOS XE Software is prone to a remote authentication-bypass vulnerability. Exploiting this issue could allow an attacker to bypass certain security restrictions and perform unauthorized actions with elevated privileges on the device running the vulnerable application. This issue is tracked by Cisco Bug ID CSCuj90227. The vulnerability is caused by the program not properly validating the Linux-IOS internal network configuration
