Summary
PhpSpreadsheet vulnerable to SSRF when reading and displaying a processed HTML document in the browser
Details

Product: PhpSpreadsheet Version: 3.8.0 CWE-ID: CWE-918: Server-Side Request Forgery (SSRF) CVSS vector v.3.1: 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) CVSS vector v.4.0: 8.7 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N) Description: SSRF occurs when a processed HTML document is read and displayed in the browser Impact: Server-Side Request Forgery Vulnerable component: the PhpOffice\PhpSpreadsheet\Worksheet\Drawing class, setPath method Exploitation conditions: getting a string from the user that is passed to the HTML reader Mitigation: improved processing of the $path variable of the setPath method of the PhpOffice\PhpSpreadsheet\Worksheet\Drawing class is needed Researcher: Aleksey Solovev (Positive Technologies)

Research

The researcher discovered zero-day vulnerability Server-Side Request Forgery (SSRF) (in the setPath method of the PhpOffice\PhpSpreadsheet\Worksheet\Drawing class) in Phpspreadsheet. The latest version (3.8.0) of the phpoffice/phpspreadsheet library was installed. Below are the details of the installation:

Listing 1. Installing the phpoffice/phpspreadsheet library $ composer require phpoffice/phpspreadsheet --prefer-source The code that processes the HTML string with further rendering and displaying the result in the browser. Listing 2. Executable file index.php using the PhpSpreadsheet library ```

load($inputFileName); $writer = new \PhpOffice\PhpSpreadsheet\Writer\Html($spreadsheet); print($writer->generateHTMLAll()); ``` Also, the `./doc/file.html` has the following content: the `img` tag with the `src` attribute, which contains the value `http:// 127.0.0.1:1337` *Listing 3. The ./doc/file.html file* ```
``` The vulnerability lies in the `setPath` method of the `PhpOffice\PhpSpreadsheet\Worksheet\Drawing` class. Figure 1. The `PhpOffice\PhpSpreadsheet\Worksheet\Drawing` class, `setPath` method. ![fig1](https://github.com/user-attachments/assets/75433f59-fac6-46d5-bcfd-6d0174bfcedd) Figure 2 below demonstrates the SSRF vulnerability exploitation. ![fig2](https://github.com/user-attachments/assets/3601692b-b077-420f-a2fb-8af0b66b6475) Figure 2. Demonstration of the SSRF vulnerability exploitation Also, there is code on line 154 that could potentially be used by an attacker to perform unsafe deserialization via the `phar` archive and the `file_exists` method. Figure 3. Opportunity to perform phar deserialization ![fig3](https://github.com/user-attachments/assets/3d7d4fc2-1b89-4925-82fa-e21c773efd47) _____________________________________________ Please, assign all credits to: Aleksey Solovev (Positive Technologies) # Credit Aleksey Solovev (Positive Technologies) ?>
