Deserialization Of Untrusted Data

H2O-3 is vulnerable to Deserialization Of Untrusted Data. The vulnerability is due to unsafe deserialization due to user-controlled JDBC URLs being passed to DriverManager.getConnection, which can trigger deserialization of untrusted data when MySQL or PostgreSQL drivers are available in the...

Arbitrary File Overwrite

H2O-3 is vulnerable to Arbitrary File Overwrite. The vulnerability is due to improper input validation due to the exportModelDetails function in ModelsHandler.java allowing user-controlled input in the mexport.dir parameter, enabling overwriting files at arbitrary locations on the host system...

CVE-2024-7765

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...

CVE-2024-7768

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...

CVE-2024-10572

In h2oai/h2o-3 version 3.46.0.1, the runtool 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-2024-10549

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...

CVE-2024-10550

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,...

CVE-2024-10553

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...

CVE-2024-6854

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...

CVE-2024-8616

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...

H2O Vulnerable to Arbitrary File Overwrite

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...

GHSA-G48V-3P35-88JR H2O Vulnerable to Arbitrary File Overwrite

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...

H2O Vulnerable to Denial of Service (DoS) via `HEAD` Request

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-controll...

Synchronous Access of Remote Resource without Timeout

Overview Affected versions of this package are vulnerable to Synchronous Access of Remote Resource without Timeout via the typeahead endpoint due to lacking timeout when checking that a specified resource exists. An attacker can cause the application to block and become unresponsive to other...

GHSA-5C8J-G96X-CJ78 H2O Vulnerable to Denial of Service (DoS) via `HEAD` Request

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-controll...

Improper Handling of Highly Compressed Data (Data Amplification)

Overview Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data Data Amplification due to the improper handling of highly compressed data. An attacker can cause the server to become unresponsive and exhaust system memory by uploading and repeatedly parsing...

GHSA-P2VC-M5FV-9W9M H2O Vulnerable to Denial of Service (DoS) via `/3/ImportFiles` Endpoint
