| Vulnerability | Title and context | CVSS | EPSS | PoCs | Signals | STIX action |
|---|---|---|---|---|---|---|
CVE-2021-3978HIGH | Improper Preservation of Permissions in github.com/cloudflare/cfrpki/cmd/octorpkiWhen 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 ) this could allow for a vector, when combined with another vulnerability that causes octorpki to process a malicious TAL file, for a local privilege escalation. | CVSS7.5v3.1 | EPSS0.142% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2022-3616MEDIUM | OctoRPKI crash when maximum iterations number is reachedAttackers 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 Mirdita and Haya Shulman - Fraunhofer SIT, ATHENE, who discovered and reported this vulnerability. | CVSS5.4v3.1 | EPSS0.415% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2021-3912MEDIUM | OctoRPKI crashes when processing GZIP bomb returned via malicious repositoryOctoRPKI 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). | CVSS4.2v3.1 | EPSS0.822% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2021-3911MEDIUM | Misconfigured IP address field in ROA leads to OctoRPKI crashIf the ROA that a repository returns contains too many bits for the IP address then OctoRPKI will crash. | CVSS4.2v3.1 | EPSS0.878% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2021-3910MEDIUM | NUL character in ROA causes OctoRPKI to crashOctoRPKI crashes when encountering a repository that returns an invalid ROA (just an encoded NUL (\0) character). CWE-20Nov 11, 2021 | CVSS4.4v3.1 | EPSS1.26% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2021-3909MEDIUM | Infinite open connection causes OctoRPKI to hang foreverOctoRPKI 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 feeding new bytes to keep the connection alive. CWE-400Nov 11, 2021 | CVSS4.4v3.1 | EPSS1.51% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2021-3908MEDIUM | Infinite certificate chain depth results in OctoRPKI running foreverOctoRPKI 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. | CVSS5.9v3.1 | EPSS0.707% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2021-3907HIGH | Arbitrary filepath traversal via URI injectionOctoRPKI 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 OctoRPKI is running on. | CVSS7.4v3.1 | EPSS4.06% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2021-3761HIGH | OctoRPKI lacks contextual out-of-bounds check when validating RPKI ROA maxLength valuesAny 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) prior to launching a BGP hijack which during normal operations would be rejected as "RPKI invalid". Additionally, in certain deployments RTR session flapping in and of itself also could cause BGP routing churn, causing availability issues. | CVSS7.5v3.1 | EPSS1.22% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
