Cloudflare: Security Vulnerabilities
Cloudflare WARP client for Windows (up to v. 2022.5.309.0) allowed creation of mount points from its ProgramData folder. During installation of the WARP client, it was possible to escalate privileges and overwrite SYSTEM protected files.

Cloudflare Warp for Windows from version 2022.2.95.0 contained an unquoted service path which enables arbitrary code execution leading to privilege escalation. The fix was released in version 2022.3.186.0.

If the ROA that a repository returns contains too many bits for the IP address then OctoRPKI will crash.

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 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.

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 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 crashes when encountering a repository that returns an invalid ROA (just an encoded NUL (\0) character).

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.
