Quick assessment

Affected
NLnet Labs Routinator
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

NLnet Labs Routinator是荷兰NLnet Labs的一款使用Rust语言编写的RPKI（资源公钥基础设施）验证器。 NLnet Labs Routinator 0.9.0至0.11.2版本存在安全漏洞，该漏洞源于错误处理中的错误，RRDP快照和增量文件中没有正确编码base64的数据将被视为致命错误，并导致Routinator退出。该漏洞的最坏影响是拒绝为Routinator提供给路由器的RPKI数据提供服务。这可能会阻止网络基于RPKI数据验证路由起源。此漏洞不允许攻击者操纵RPKI数

Vulnerability Title
Fatal error on incorrect base64 data in RRDP
Source: CVE Program / CVE List V5
Vulnerability Description
In NLnet Labs Routinator 0.9.0 up to and including 0.11.2, due to a mistake in error handling, data in RRDP snapshot and delta files that isn’t correctly base 64 encoded is treated as a fatal error and causes Routinator to exit. Worst case impact of this vulnerability is denial of service for the RPKI data that Routinator provides to routers. This may stop your network from validating route origins based on RPKI data. This vulnerability does not allow an attacker to manipulate RPKI data.
