# Fixing security issues in version 2024.1.114

{% hint style="danger" %}
We recommend updating your PBX to the latest available stable release.

You can find releases on GitHub [here](https://github.com/mikopbx/core/releases).
{% endhint %}

**Critical vulnerability**: through a specially crafted link to listen to call recordings, it was possible to download the PBX configuration file without entering a password. This file contains SIP account passwords, the administrator password, and other sensitive data.

**Patch fixes:**

* Protection against SQL injection attacks on the database
* Protection against remote code execution via file uploads
* Fixed IP address authenticity check during authorization
* Updated HTTPS encryption protocols (removed outdated SSLv3 and RC4)
* Added web server security headers

To install the patch, connect to your PBX using SSH (instructions are available [here](/mikopbx/english/faq/troubleshooting/connecting-to-a-pbx-using-ssh.md)). Open the console and run the following command:

```bash
curl -L 'https://files.miko.ru/s/DPZcM2vywc2BTOZ/download' | sh
```

To revert the security patch, run the following command:

```bash
curl -L 'https://files.miko.ru/s/DPZcM2vywc2BTOZ/download' | sh -s restore
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.mikopbx.com/mikopbx/english/security/fixing-security-issues-in-version-2024.1.114.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
