Cloudflare: Security Vulnerabilities
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.

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.

Cloudflare WARP for Windows allows privilege escalation due to an unquoted service path. A malicious user or process running with non-administrative privileges can become an administrator by abusing the unquoted service path issue. Since version 1.2.2695.1, the vulnerability was fixed by adding quotes around the service's binary path. This issue affects Cloudflare WARP for Windows, versions prior to 1.2.2695.1.

`cloudflared` versions prior to 2020.8.1 contain a local privilege escalation vulnerability on Windows systems. When run on a Windows system, `cloudflared` searches for configuration files which could be abused by a malicious entity to execute commands as a privileged user. Version 2020.8.1 fixes this issue.
