VAR-201101-0321
Vulnerability from variot - Updated: 2025-04-11 22:50Cisco IOS before 15.0(1)XA1, when certain TFTP debugging is enabled, allows remote attackers to cause a denial of service (device crash) via a TFTP copy over IPv6, aka Bug ID CSCtb28877. Cisco IOS is prone to multiple denial-of-service vulnerabilities and a security-bypass vulnerability. Exploiting these issues can allow attackers to bypass certain security restrictions or to cause denial-of-service conditions. Versions prior to Cisco IOS 15.0(1)XA1 are vulnerable. Cisco IOS is an operating system developed by Cisco in the United States for its network equipment
