CVE-2023-2512 1 Cloudflare 1 Workerd 2024-02-28 N/A 8.1 HIGH
Prior to version v1.20230419.0, the FormData API implementation was subject to an integer overflow. If a FormData instance contained more than 2^31 elements, the forEach() method could end up reading from the wrong location in memory while iterating over elements. This would most likely lead to a segmentation fault, but could theoretically allow arbitrary undefined behavior. In order for the bug to be exploitable, the process would need to be able to allocate 160GB of RAM. Due to this, the bug was never exploitable on the Cloudflare Workers platform, but could theoretically be exploitable on deployments of workerd running on machines with a huge amount of memory. Moreover, in order to be remotely exploited, an attacker would have to upload a single form-encoded HTTP request of at least tens of gigabytes in size. The application code would then have to use request.formData() to parse the request and formData.forEach() to iterate over this data. Due to these limitations, the exploitation likelihood was considered Low. A fix that addresses this vulnerability has been released in version v1.20230419.0 and users are encouraged to update to the latest version available.
CVE-2023-1732 1 Cloudflare 1 Circl 2024-02-28 N/A 8.2 HIGH
When sampling randomness for a shared secret, the implementation of Kyber and FrodoKEM, did not check whether crypto/rand.Read() returns an error. In rare deployment cases (error thrown by the Read() function), this could lead to a predictable shared secret. The tkn20 and blindrsa components did not check whether enough randomness was returned from the user provided randomness source. Typically the user provides crypto/rand.Reader, which in the vast majority of cases will always return the right number random bytes. In the cases where it does not, or the user provides a source that does not, the blinding for blindrsa is weak and integrity of the plaintext is not ensured in tkn20.
CVE-2022-4457 1 Cloudflare 1 Warp 2024-02-28 N/A 5.5 MEDIUM
Due to a misconfiguration in the manifest file of the WARP client for Android, it was possible to a perform a task hijacking attack. An attacker could create a malicious mobile application which could hijack legitimate app and steal potentially sensitive information when installed on the victim's device.
CVE-2014-125026 1 Cloudflare 1 Golz4 2024-02-28 N/A 9.8 CRITICAL
LZ4 bindings use a deprecated C API that is vulnerable to memory corruption, which could lead to arbitrary code execution if called with untrusted user input.
CVE-2022-4428 1 Cloudflare 1 Warp 2024-02-28 N/A 8.0 HIGH
support_uri parameter in the WARP client local settings file (mdm.xml) lacked proper validation which allowed for privilege escalation and launching an arbitrary executable on the local machine upon clicking on the "Send feedback" option. An attacker with access to the local file system could use a crafted XML config file pointing to a malicious file or set a local path to the executable using Cloudflare Zero Trust Dashboard (for Zero Trust enrolled clients).
CVE-2022-3320 1 Cloudflare 1 Warp 2024-02-28 N/A 9.8 CRITICAL
It was possible to bypass policies configured for Zero Trust Secure Web Gateway by using warp-cli 'set-custom-endpoint' subcommand. Using this command with an unreachable endpoint caused the WARP Client to disconnect and allowed bypassing administrative restrictions on a Zero Trust enrolled endpoint.
CVE-2022-2529 1 Cloudflare 1 Goflow 2024-02-28 N/A 7.5 HIGH
sflow decode package does not employ sufficient packet sanitisation which can lead to a denial of service attack. Attackers can craft malformed packets causing the process to consume large amounts of memory resulting in a denial of service.
CVE-2022-3616 1 Cloudflare 1 Octorpki 2024-02-28 N/A 7.5 HIGH
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.

CVE-2022-3512 1 Cloudflare 1 Warp 2024-02-28 N/A 8.8 HIGH
Using warp-cli command "add-trusted-ssid", a user was able to disconnect WARP client and bypass the "Lock WARP switch" feature resulting in Zero Trust policies not being enforced on an affected endpoint.
CVE-2022-3322 1 Cloudflare 1 Warp Mobile Client 2024-02-28 N/A 7.5 HIGH
Lock Warp switch is a feature of Zero Trust platform which, when enabled, prevents users of enrolled devices from disabling WARP client. Due to insufficient policy verification by WARP iOS client, this feature could be bypassed by using the "Disable WARP" quick action.
CVE-2022-3337 1 Cloudflare 1 Warp Mobile Client 2024-02-28 N/A 8.5 HIGH
It was possible for a user to delete a VPN profile from WARP mobile client on iOS platform despite the Lock WARP switch https://developers.cloudflare.com/cloudflare-one/connections/connect-devices/warp/warp-settings/#lock-warp-switch  feature being enabled on Zero Trust Platform. This led to bypassing policies and restrictions enforced for enrolled devices by the Zero Trust platform.
CVE-2022-3321 1 Cloudflare 1 Warp Mobile Client 2024-02-28 N/A 8.2 HIGH
It was possible to bypass Lock WARP switch feature https://developers.cloudflare.com/cloudflare-one/connections/connect-devices/warp/warp-settings/#lock-warp-switch  on the WARP iOS mobile client by enabling both "Disable for cellular networks" and "Disable for Wi-Fi networks" switches at once in the application settings. Such configuration caused the WARP client to disconnect and allowed the user to bypass restrictions and policies enforced by the Zero Trust platform.
CVE-2022-2225 1 Cloudflare 1 Warp 2024-02-28 N/A 7.8 HIGH
By using warp-cli subcommands (disable-ethernet, disable-wifi), it was possible for a user without admin privileges to bypass configured Zero Trust security policies (e.g. Secure Web Gateway policies) and features such as 'Lock WARP switch'.
CVE-2022-2147 1 Cloudflare 1 Warp 2024-02-28 4.6 MEDIUM 7.8 HIGH
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.
CVE-2022-2145 1 Cloudflare 1 Warp 2024-02-28 7.2 HIGH 7.8 HIGH
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.
CVE-2021-3907 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2024-02-28 7.5 HIGH 9.8 CRITICAL
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.
CVE-2021-3911 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2024-02-28 4.3 MEDIUM 6.5 MEDIUM
If the ROA that a repository returns contains too many bits for the IP address then OctoRPKI will crash.
CVE-2021-3912 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2024-02-28 4.3 MEDIUM 6.5 MEDIUM
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).
CVE-2021-3910 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2024-02-28 5.0 MEDIUM 7.5 HIGH
OctoRPKI crashes when encountering a repository that returns an invalid ROA (just an encoded NUL (\0) character).
CVE-2021-3909 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2024-02-28 5.0 MEDIUM 7.5 HIGH
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.
