h2oai/h2o-3: Improper Control of Generation of Code
A critical remote code execution vulnerability exists in the unauthenticated REST API endpoint /99/ImportSQLTable in H2O-3 version 3.46.0.9 and prior. The vulnerability arises due to insufficient security controls in the parameter blacklist mechanism, which on
- 9.1 Critical severity
h2oai/h2o-3: External Control of File Name or Path
A vulnerability in h2oai/h2o-3 version 3.46.0.1 allows remote attackers to write arbitrary data to any file on the server. This is achieved by exploiting the `/3/Parse` endpoint to inject attacker-controlled data as the header of an empty file, which is then e
- 9.8 Critical severity
h2oai/h2o-3: Deserialization of Untrusted Data
A deserialization vulnerability exists in h2oai/h2o-3 versions <= 3.46.0.8, allowing attackers to read arbitrary system files and execute arbitrary code. The vulnerability arises from improper handling of JDBC connection parameters, which can be exploited by b
- 9.8 Critical severity
h2oai/h2o-3: Deserialization of Untrusted Data
A deserialization vulnerability exists in the H2O-3 REST API (POST /99/ImportSQLTable) that affects all versions up to 3.46.0.7. This vulnerability allows remote code execution (RCE) due to improper validation of JDBC connection parameters when using a Key-Val
- 9.8 Critical severity
h2oai/h2o-3: Deserialization of Untrusted Data
A vulnerability in the h2oai/h2o-3 repository allows attackers to exploit deserialization of untrusted data, potentially leading to arbitrary code execution and reading of system files. This issue affects the latest master branch version 3.47.0.99999. The vuln
- 8.2 High severity
h2oai/h2o-3: External Control of File Name or Path
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` pa
- 7.5 High severity
h2oai/h2o-3: Synchronous Access of Remote Resource without Timeout
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 mu
- 7.5 High severity
h2oai/h2o-3: Allocation of Resources Without Limits or Throttling
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 repeat
- 7.5 High severity
h2oai/h2o-3: Improper Handling of Highly Compressed Data (Data Amplification)
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 is
- 7.1 High severity
h2oai/h2o-3: Absolute Path Traversal
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
- 7.5 High severity
h2oai/h2o-3: Improper Control of Generation of Code
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 di
- 9.8 Critical severity
h2oai/h2o-3: Deserialization of Untrusted Data
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
- 7.5 High severity
h2oai/h2o-3: Inefficient Regular Expression Complexity
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 i
- 7.5 High severity
h2oai/h2o-3: Inefficient Regular Expression Complexity
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 send
- 7.5 High severity
h2oai/h2o-3: Improper Control of Generation of Code
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,
- 7.1 High severity
