Improper Preservation of Permissions in github.com/cloudflare/cfrpki/cmd/octorpki
When copying files with rsync, octorpki uses the "-a" flag 0, which forces rsync to copy binaries with the suid bit set as root. Since the provided service definition defaults to root ( https://github.com/cloudflare/cfrpki/blob/master/package/octorpki.service…

OctoRPKI crash when maximum iterations number is reached
Attackers can create long chains of CAs that would lead to OctoRPKI exceeding its max iterations parameter. In consequence it would cause the program to crash, preventing it from finishing the validation and leading to a denial of service. Credits to Donika M…

OctoRPKI crashes when processing GZIP bomb returned via malicious repository
OctoRPKI tries to load the entire contents of a repository in memory, and in the case of a GZIP bomb, unzip it in memory, making it possible to create a repository that makes OctoRPKI run out of memory (and thus crash).

Misconfigured IP address field in ROA leads to OctoRPKI crash
If the ROA that a repository returns contains too many bits for the IP address then OctoRPKI will crash.

NUL character in ROA causes OctoRPKI to crash
OctoRPKI crashes when encountering a repository that returns an invalid ROA (just an encoded NUL (\0) character).

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 respons…

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.

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 re…

gzip transfer encoding caused out-of-memory crash
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…

Hanging RRDP request
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…

OctoRPKI lacks contextual out-of-bounds check when validating RPKI ROA maxLength values
Any CA issuer in the RPKI can trick OctoRPKI prior to 1.3.0 into emitting an invalid VRP "MaxLength" value, causing RTR sessions to terminate. An attacker can use this to disable RPKI Origin Validation in a victim network (for example AS 13335 - Cloudflare) p…
