CVE-2024-7768

The CVE-2024-7768 issue affects h2oai/h2o-3 (v3.46.1) and its /3/ImportFiles endpoint. The root cause is improper handling of the GET parameter path, which can be recursively set to reference itself, making the server repeatedly call its own endpoint. Practical impact is a Denial of Service, fill...

CVE-2024-7768 Denial of Service in h2oai/h2o-3

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-2024-6863 Encryption of Arbitrary Files with Attacker-Controlled Key in h2oai/h2o-3

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 attacke...

CVE-2024-6863

CVE-2024-6863 affects h2oai/h2o-3 v3.46.0 through an endpoint exposing a custom EncryptionTool that allows an attacker to encrypt arbitrary files on the target server with a key of their choosing, with the key potentially overwritable and ransomware-like behavior described. The vulnerability’s im...

CVE-2024-8616 Arbitrary File Overwrite in h2oai/h2o-3

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...

CVE-2024-8616

CVE-2024-8616 affects h2oai/h2o-3 v3.46.0. The flaw resides in the /99/Models/{name}/json handler where user-controllable exportModelDetails uses the mexport.dir parameter to choose the file path, enabling arbitrary file overwrite on the host. This is due to inadequate validation in the underlyin...
