CVE-2021-3911

CVE-2021-3911 : In Cloudflare’s CFRPKI/OctoRPKI stack, a ROA response containing too many bits for the IP address can cause OctoRPKI to crash, i.e., an availability issue. The vulnerability is triggered when the ROA payload’s IP bit width exceeds expected limits, leading to a crash rather than a ...

CVE-2021-3910

CVE-2021-3910 concerns Cloudflare’s CFRpki/OctoRPKI where processing a repository ROA that is just a NUL character can cause a crash. Connected sources confirm this vulnerability in CFRpki/OctoRPKI (e.g., GO-2022-0251 and OSV/NVD copies) and note the issue arises from an invalid ROA payload. The ...

CVE-2021-3909

OctoRPKI does not limit the length of a connection, allowing for a slowloris DOS attack to take place which makes OctoRPKI wait forever. Specifically, the repository that OctoRPKI sends HTTP requests to will keep the connection open for a day before a response is returned, but does keep drip...

CVE-2021-3909 Infinite open connection causes OctoRPKI to hang forever

OctoRPKI does not limit the length of a connection, allowing for a slowloris DOS attack to take place which makes OctoRPKI wait forever. Specifically, the repository that OctoRPKI sends HTTP requests to will keep the connection open for a day before a response is returned, but does keep drip...

CVE-2021-3909

CVE-2021-3909 affects OctoRPKI: the vulnerable component does not bound connection length, enabling a slowloris-style DOS where the target repository keeps the HTTP connection open (up to about a day) while drip-feeding data. This can cause the OctoRPKI service to hang, impacting availability. Co...

CVE-2021-3908

CVE-2021-3908 affects Cloudflare’s CFRpki/OctoRPKI validator. The issue: an unlimited certificate-chain depth allows tree traversal to recurse indefinitely, potentially leading to denial of service or path traversal. Affected component: CFRpki/OctoRPKI (RPKI validator). Root cause: no limit on ce...

CVE-2021-3908 Infinite certificate chain depth results in OctoRPKI running forever

OctoRPKI does not limit the depth of a certificate chain, allowing for a CA to create children in an ad-hoc fashion, thereby making tree traversal never end...

CVE-2021-3907 Arbitrary filepath traversal via URI injection

OctoRPKI does not escape a URI with a filename containing "..", this allows a repository to create a file, ex. rsync://example.org/repo/../../etc/cron.daily/evil.roa, which would then be written to disk outside the base cache folder. This could allow for remote code execution on the host machine...
