| CVE-2023-3040 | 1 Cloudflare | 1 Lua-resty-json | 2023-12-10 | N/A | 7.5 HIGH |
| A debug function in the lua-resty-json package, up to commit id 3ef9492bd3a44d9e51301d6adc3cd1789c8f534a (merged in PR #14) contained an out of bounds access bug that could have allowed an attacker to launch a DoS if the function was used to parse untrusted input data. It is important to note that because this debug function was only used in tests and demos, it was not exploitable in a normal environment. | |||||
| CVE-2023-1412 | 1 Cloudflare | 1 Warp | 2023-12-10 | N/A | 7.8 HIGH |
| An unprivileged (non-admin) user can exploit an Improper Access Control vulnerability in the Cloudflare WARP Client for Windows (<= 2022.12.582.0) to perform privileged operations with SYSTEM context by working with a combination of opportunistic locks (oplock) and symbolic links (which can both be created by an unprivileged user). After installing the Cloudflare WARP Client (admin privileges required), an MSI-Installer is placed under C:\Windows\Installer. The vulnerability lies in the repair function of this MSI. ImpactAn unprivileged (non-admin) user can exploit this vulnerability to perform privileged operations with SYSTEM context, including deleting arbitrary files and reading arbitrary file content. This can lead to a variety of attacks, including the manipulation of system files and privilege escalation. PatchesA new installer with a fix that addresses this vulnerability was released in version 2023.3.381.0. While the WARP Client itself is not vulnerable (only the installer), users are encouraged to upgrade to the latest version and delete any older installers present in their systems. | |||||
| CVE-2022-4428 | 1 Cloudflare | 1 Warp | 2023-12-10 | 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-2022-4457 | 1 Cloudflare | 1 Warp | 2023-12-10 | 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 | 2023-12-10 | 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-2022-3322 | 1 Cloudflare | 1 Warp Mobile Client | 2023-12-10 | 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-2022-3616 | 1 Cloudflare | 1 Octorpki | 2023-12-10 | 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. Credits to Donika Mirdita and Haya Shulman - Fraunhofer SIT, ATHENE, who discovered and reported this vulnerability. | |||||
| CVE-2022-3321 | 1 Cloudflare | 1 Warp Mobile Client | 2023-12-10 | 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-2022-3320 | 1 Cloudflare | 1 Warp | 2023-12-10 | 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-2022-3337 | 1 Cloudflare | 1 Warp Mobile Client | 2023-12-10 | 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-2022-3512 | 1 Cloudflare | 1 Warp | 2023-12-10 | 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-2022-2529 | 1 Cloudflare | 1 Goflow | 2023-12-10 | 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-2022-2225 | 1 Cloudflare | 1 Warp | 2023-12-10 | 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 | 2023-12-10 | 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 | 2023-12-10 | 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-2021-3912 | 2 Cloudflare, Debian | 2 Octorpki, Debian Linux | 2023-12-10 | 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-2021-3907 | 2 Cloudflare, Debian | 2 Octorpki, Debian Linux | 2023-12-10 | 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-2021-3910 | 2 Cloudflare, Debian | 2 Octorpki, Debian Linux | 2023-12-10 | 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 | 2023-12-10 | 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. | |||||
| CVE-2021-3761 | 2 Cloudflare, Debian | 2 Octorpki, Debian Linux | 2023-12-10 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
