CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-3978 – Improper Preservation of Permissions in github.com/cloudflare/cfrpki/cmd/octorpki
https://notcve.org/view.php?id=CVE-2021-3978
29 Jan 2025 — 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 ) 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. • https://github.com/cloudflare/cfrpki/security/advisories/GHSA-3pqh-p72c-fj85 • CWE-269: Improper Privilege Management •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2022-3616 – OctoRPKI crash when maximum iterations number is reached
https://notcve.org/view.php?id=CVE-2022-3616
28 Oct 2022 — 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 Mirdita and Haya Shulman - Fraunhofer SIT, ATHENE, who discovered and reported this vulnerability.

CVSS: 6.5EPSS: 0%CPEs: 2EXPL: 0CVE-2021-3912 – OctoRPKI crashes when processing GZIP bomb returned via malicious repository
https://notcve.org/view.php?id=CVE-2021-3912
11 Nov 2021 — 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). OctoRPKI intenta cargar todo el contenido de un repositorio en memoria, y en el caso de una bomba GZIP, descomprimirlo en memoria, haciendo posible crear un repositorio que hace que OctoRPKI se quede sin memoria (y por tanto se bloquee) Multiple vulnerabilities were discovered in Cloudflare'... • https://github.com/cloudflare/cfrpki/security/advisories/GHSA-g9wh-3vrx-r7hg • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2021-3911
11 Nov 2021 — If the ROA that a repository returns contains too many bits for the IP address then OctoRPKI will crash. Si el ROA que devuelve un repositorio contiene demasiados bits para la dirección IP, OctoRPKI será bloqueado Multiple vulnerabilities were discovered in Cloudflare's RPKI validator, which could result in denial of service or path traversal. • https://github.com/cloudflare/cfrpki/security/advisories/GHSA-w6ww-fmfx-2x22 • CWE-20: Improper Input Validation CWE-252: Unchecked Return Value •

11 Nov 2021 — OctoRPKI crashes when encountering a repository that returns an invalid ROA (just an encoded NUL (\0) character). OctoRPKI es bloqueado cuando encuentra un repositorio que devuelve un ROA inválido (sólo un carácter NUL (\0) codificado) Multiple vulnerabilities were discovered in Cloudflare's RPKI validator, which could result in denial of service or path traversal. • https://github.com/cloudflare/cfrpki/security/advisories/GHSA-5mxh-2qfv-4g7j • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2021-3909
11 Nov 2021 — 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 feeding new bytes to keep the connection alive. OctoRPKI no limita la duración de una conexión, permitiendo que se produzca un ataque slowloris DOS que hace que OctoRPKI espere eternamente.

https://notcve.org/view.php?id=CVE-2021-3908
11 Nov 2021 — 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. OctoRPKI no limita la profundidad de una cadena de certificados, permitiendo que una CA cree hijos de forma ad-hoc, haciendo que el recorrido del árbol nunca termine Multiple vulnerabilities were discovered in Cloudflare's RPKI validator, which could result in denial of service or path traversal. • https://github.com/cloudflare/cfrpki/security/advisories/GHSA-g5gj-9ggf-9vmq • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

https://notcve.org/view.php?id=CVE-2021-3907
11 Nov 2021 — 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. • https://github.com/cloudflare/cfrpki/security/advisories/GHSA-3jhm-87m6-x959 • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2021-3761 – OctoRPKI lacks contextual out-of-bounds check when validating RPKI ROA maxLength values
https://notcve.org/view.php?id=CVE-2021-3761
09 Sep 2021 — 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) 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.
