ChestnutCMS API Endpoint exec deserialization

A vulnerability was found in ChestnutCMS up to 15.1. It has been declared as critical. This vulnerability affects unknown code of the file /dev-api/groovy/exec of the component API Endpoint. The manipulation leads to deserialization. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.

ChestnutCMS read readFile path traversal

A vulnerability, which was classified as problematic, was found in ChestnutCMS up to 1.5.3. Affected is the function readFile of the file /dev-api/cms/file/read. The manipulation of the argument filePath leads to path traversal. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.

ChestnutCMS <=1.5.0 is vulnerable to File Upload via the Create template function.

ChestnutCMS <=1.5.0 has an arbitrary file deletion vulnerability in contentcore.controller.FileController, which allows attackers to delete any file and folder.

ChestnutCMS <=1.5.0 has a directory traversal vulnerability in contentcore.controller.FileController#getFileList, which allows attackers to view any directory.

ChestnutCMS upload uploadFile unrestricted upload

A vulnerability classified as critical has been found in ChestnutCMS up to 1.5.2. This affects the function uploadFile of the file /dev-api/cms/file/upload. The manipulation of the argument file leads to unrestricted upload. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.

ChestnutCMS rename renameFile path traversal

A vulnerability classified as problematic was found in ChestnutCMS 1.5.2. This vulnerability affects the function renameFile of the file /cms/file/rename. The manipulation of the argument rename leads to path traversal. The exploit has been disclosed to the public and may be used.

File Upload vulnerability in ChestnutCMS through 1.5.0. Based on the code analysis, it was determined that the /api/member/avatar API endpoint receives a base64 string as input. This string is then passed to the memberService.uploadAvatarByBase64 method for processing. Within the service, the base64-encoded image is parsed. For example, given a string like: data:image/html;base64,PGh0bWw+PGltZyBzcmM9eCBvbmVycm9yPWFsZXJ0KDEpPjwvaHRtbD4= the content after the comma is extracted and decoded using Base64.getDecoder().decode(). The substring from the 11th character up to the first occurrence of a semicolon (;) is assigned to the suffix variable (representing the file extension). The decoded content is then written to a file. However, the file extension is not validated, and since this functionality is exposed to the frontend, it poses significant security risks.
