NVD Description

A vulnerability in the Cisco GroupEncrypted Transport VPN (GET VPN) feature of Cisco IOS Software and Cisco IOSXE Software could allow an authenticated, remote attacker who hasadministrative control of either a group member or a key server to executearbitrary code on an affected device or cause the device to crash.

This vulnerability is due toinsufficient validation of attributes in the Group Domain of Interpretation(GDOI) and G-IKEv2 protocols of the GET VPN feature. An attacker could exploitthis vulnerability by either compromising an installed key server or modifyingthe configuration of a group member to point to a key server that is controlledby the attacker. A successful exploit could allow the attacker to executearbitrary code and gain full control of the affected system or cause theaffected system to reload, resulting in a denial of service (DoS) condition.For more information, see the Details ["#details"] section of thisadvisory.
