CVE-2022-3616
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAttackers 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceAttackers can craft long CA certificate chains that exceed OctoRPKI's configured max iterations parameter, causing the program to crash during RPKI validation and resulting in denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Cloudflare OctoRPKI is installedLocate the octorpki binary or package on the system using package managers, file system searches, or process enumerationAffected if Cloudflare OctoRPKI is present on the system
-
Determine the installed version of OctoRPKIRun the version command for octorpki (e.g., octorpki --version or octorpki -v) or inspect the installed package metadataAffected if The version is lower than 1.4.4 (e.g., 1.4.3, 1.4.0, etc.)
-
Check if RPKI validation is actively configuredInspect the octorpki configuration files or running parameters to determine if RPKI CA certificate chain validation is enabledAffected if RPKI validation is enabled and processing incoming CA certificates
-
Identify the max iterations configurationReview octorpki configuration files or runtime settings for the max iterations parameter that controls certificate chain traversal limitsAffected if A max iterations parameter exists and is set to a finite value (default or custom configuration)
-
Verify the running process behaviorMonitor octorpki during RPKI validation operations or check logs for crash events related to certificate chain processingAffected if The process crashes or terminates when processing long certificate chains
The environment is affected if Cloudflare OctoRPKI version below 1.4.4 is installed and RPKI validation with certificate chain processing is actively in use.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.4.4
Implement graceful handling when iteration limits are reached (e.g., return error instead of crash) and add validation to detect abnormally long certificate chains before processing.
1.4.4
- 1. Identify the current installed version of OctoRPKI by running 'octorpki --version' or checking the package manager
- 2. If using a package manager (e.g., apt, yum, docker), update to version 1.4.4 or later
- 3. For manual installations, download the fixed release from the official GitHub repository
- 4. Replace the existing binary/package with version 1.4.4
- 5. Restart the OctoRPKI service to apply the update
- 6. Verify the new version is running correctly: 'octorpki --version'
