CVE-2020-16163 (GCVE-0-2020-16163)

Vulnerability from cvelistv5 – Published: 2020-07-30 15:16 – Updated: 2024-08-04 13:37 Disputed

Summary

An issue was discovered in RIPE NCC RPKI Validator 3.x before 3.1-2020.07.06.14.28. RRDP fetches proceed even with a lack of validation of a TLS HTTPS endpoint. This allows remote attackers to bypass intended access restrictions, or to trigger denial of service to traffic directed to co-dependent routing systems. NOTE: third parties assert that the behavior is intentionally permitted by RFC 8182

Severity
