Technical details
A vulnerability in NLnet Labs Routinator up to version 0.15.1 is caused by improper input validation of the 'select-asn' query parameter at the /api/v1/origins endpoint. When the application receives a specifically crafted non-UTF-8 string in this parameter, it triggers a panic (crash) during string parsing. The attack can be executed remotely without authentication if the API endpoint is reachable over the network. This results in a complete loss of availability for the Routinator service. The issue is resolved in version 0.15.2.
