CVE-2021-43172

NLnet Labs Routinator (pre-0.10.2) is vulnerable to an infinite validation loop when processing an RRDP chain. The flaw arises because there is no limit on the length of a chain of RRDP repositories, enabling a malicious CA to generate an effectively infinite chain of CAs that reference different...

CVE-2021-43172 Infinite length chain of RRDP repositories

NLnet Labs Routinator prior to 0.10.2 happily processes a chain of RRDP repositories of infinite length causing it to never finish a validation run. In RPKI, a CA can choose the RRDP repository it wishes to publish its data in. By continuously generating a new child CA that only consists of anoth...

CVE-2021-43174

NLnet Labs Routinator versions 0.9.0 up to and including 0.10.1, support the gzip transfer encoding when querying RRDP repositories. This encoding can be used by an RRDP repository to cause an out-of-memory crash in these versions of Routinator. RRDP uses XML which allows arbitrary amounts of whi...

CVE-2021-43173

In NLnet Labs Routinator prior to 0.10.2, a validation run can be delayed significantly by an RRDP repository by not answering but slowly drip-feeding bytes to keep the connection alive. This can be used to effectively stall validation. While Routinator has a configurable time-out value for RRDP...

Vulnerabilities found in RPKI validators

Researchers at the University of Twente have found vulnerabilities found in several RPKI validators. RPKI validators are used to validate that a route propagated via BGP originates from an AS that is authorized to distribute this route. propagation. The vulnerabilities make it possible for an...
