Vulnerabilities 10

  • High 7.5

    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…

    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…

  • High 7.5

    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…

  • High 7.4

    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…

  • Medium 5.9

    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.

  • Medium 4.4

    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…

  • Medium 4.4

    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).

  • Medium 4.2

    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.

  • Medium 4.2

    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).

    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…
