| CVE-2024-6854 | 1 H2o | 1 H2o | 2025-07-15 | N/A |
| In h2oai/h2o-3 version 3.46.0, the endpoint for exporting models does not restrict the export location, allowing an attacker to export a model to any file in the server's file structure, thereby overwriting it. This vulnerability can be exploited to overwrite any file on the target server with a trained model file, although the content of the overwrite is not controllable by the attacker. | ||||
| CVE-2024-6863 | 1 H2o | 1 H2o | 2025-07-15 | N/A |
| In h2oai/h2o-3 version 3.46.0, an endpoint exposing a custom EncryptionTool allows an attacker to encrypt any files on the target server with a key of their choosing. The chosen key can also be overwritten, resulting in ransomware-like behavior. This vulnerability makes it possible for an attacker to encrypt arbitrary files with keys of their choice, making it exceedingly difficult for the target to recover the keys needed for decryption. | ||||
| CVE-2024-7768 | 1 H2o | 1 H2o | 2025-07-15 | N/A |
| A vulnerability in the `/3/ImportFiles` endpoint of h2oai/h2o-3 version 3.46.1 allows an attacker to cause a denial of service. The endpoint takes a single GET parameter, `path`, which can be recursively set to reference itself. This leads the server to repeatedly call its own endpoint, eventually filling up the request queue and leaving the server unable to handle other requests. | ||||
| CVE-2024-8616 | 1 H2o | 1 H2o | 2025-07-15 | N/A |
| In h2oai/h2o-3 version 3.46.0, the `/99/Models/{name}/json` endpoint allows for arbitrary file overwrite on the target server. The vulnerability arises from the `exportModelDetails` function in `ModelsHandler.java`, where the user-controllable `mexport.dir` parameter is used to specify the file path for writing model details. This can lead to overwriting files at arbitrary locations on the host system. | ||||
| CVE-2024-5979 | 1 H2o | 1 H2o | 2025-07-15 | N/A |
| In h2oai/h2o-3 version 3.46.0, the `run_tool` command in the `rapids` component allows the `main` function of any class under the `water.tools` namespace to be called. One such class, `MojoConvertTool`, crashes the server when invoked with an invalid argument, causing a denial of service. | ||||
| CVE-2024-10549 | 1 H2o | 1 H2o | 2025-07-14 | N/A |
| A vulnerability in the `/3/Parse` endpoint of h2oai/h2o-3 version 3.46.0.1 allows for a denial of service (DoS) attack. The endpoint uses a user-specified string to construct a regular expression, which is then applied to another user-specified string. By sending multiple simultaneous requests, an attacker can exhaust all available threads, leading to a complete denial of service. | ||||
| CVE-2024-10550 | 1 H2o | 1 H2o | 2025-07-14 | N/A |
| A vulnerability in the `/3/ParseSetup` endpoint of h2oai/h2o-3 version 3.46.0.1 allows for a denial of service (DoS) attack. The endpoint applies a user-specified regular expression to a user-controllable string. This can be exploited by an attacker to cause inefficient regular expression complexity, leading to the exhaustion of server resources and making the server unresponsive. | ||||
| CVE-2024-10553 | 1 H2o | 1 H2o | 2025-07-14 | N/A |
| A vulnerability in the h2oai/h2o-3 REST API versions 3.46.0.4 allows unauthenticated remote attackers to execute arbitrary code via deserialization of untrusted data. The vulnerability exists in the endpoints POST /99/ImportSQLTable and POST /3/SaveToHiveTable, where user-controlled JDBC URLs are passed to DriverManager.getConnection, leading to deserialization if a MySQL or PostgreSQL driver is available in the classpath. This issue is fixed in version 3.47.0. | ||||
| CVE-2024-10572 | 1 H2o | 1 H2o | 2025-07-14 | N/A |
| In h2oai/h2o-3 version 3.46.0.1, the `run_tool` command exposes classes in the `water.tools` package through the `ast` parser. This includes the `XGBoostLibExtractTool` class, which can be exploited to shut down the server and write large files to arbitrary directories, leading to a denial of service. | ||||
| CVE-2023-6569 | 1 H2o | 1 H2o | 2025-05-22 | 8.2 High |
| External Control of File Name or Path in h2oai/h2o-3 | ||||
| CVE-2024-7765 | 1 H2o | 1 H2o | 2025-04-01 | 7.5 High |
| In h2oai/h2o-3 version 3.46.0.2, a vulnerability exists where uploading and repeatedly parsing a large GZIP file can cause a denial of service. The server becomes unresponsive due to memory exhaustion and a large number of concurrent slow-running jobs. This issue arises from the improper handling of highly compressed data, leading to significant data amplification. | ||||
| CVE-2024-8062 | 1 H2o | 1 H2o | 2025-03-26 | 7.5 High |
| A vulnerability in the typeahead endpoint of h2oai/h2o-3 version 3.46.0 allows for a denial of service. The endpoint performs a `HEAD` request to verify the existence of a specified resource without setting a timeout. An attacker can exploit this by sending multiple requests to an attacker-controlled server that hangs, causing the application to block and become unresponsive to other requests. | ||||
| CVE-2024-5550 | 1 H2o | 1 H2o | 2025-02-12 | 5.3 Medium |
| In h2oai/h2o-3 version 3.40.0.4, an exposure of sensitive information vulnerability exists due to an arbitrary system path lookup feature. This vulnerability allows any remote user to view full paths in the entire file system where h2o-3 is hosted. Specifically, the issue resides in the Typeahead API call, which when requested with a typeahead lookup of '/', exposes the root filesystem including directories such as /home, /usr, /bin, among others. This vulnerability could allow attackers to explore the entire filesystem, and when combined with a Local File Inclusion (LFI) vulnerability, could make exploitation of the server trivial. | ||||
| CVE-2023-6013 | 1 H2o | 1 H2o | 2024-11-27 | 5.4 Medium |
| H2O is vulnerable to stored XSS vulnerability which can lead to a Local File Include attack. | ||||
| CVE-2023-6038 | 1 H2o | 1 H2o | 2024-11-21 | 7.5 High |
| A Local File Inclusion (LFI) vulnerability exists in the h2o-3 REST API, allowing unauthenticated remote attackers to read arbitrary files on the server with the permissions of the user running the h2o-3 instance. This issue affects the default installation and does not require user interaction. The vulnerability can be exploited by making specific GET or POST requests to the ImportFiles and ParseSetup endpoints, respectively. This issue was identified in version 3.40.0.4 of h2o-3. | ||||
| CVE-2023-6017 | 1 H2o | 1 H2o | 2024-11-21 | 7.1 High |
| H2O included a reference to an S3 bucket that no longer existed allowing an attacker to take over the S3 bucket URL. | ||||
| CVE-2023-6016 | 1 H2o | 1 H2o | 2024-11-21 | 9.8 Critical |
| An attacker is able to gain remote code execution on a server hosting the H2O dashboard through it's POJO model import feature. | ||||
| CVE-2024-8862 | 2 H2o, H2oai | 2 H2o, H2o-3 | 2024-09-20 | 7.3 High |
| A vulnerability, which was classified as critical, has been found in h2oai h2o-3 3.46.0.4. This issue affects the function getConnectionSafe of the file /dtale/chart-data/1 of the component JDBC Connection Handler. The manipulation of the argument query leads to deserialization. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. | ||||
