FreePBX is an open-source web-based graphical user interface (GUI) that manages Asterisk. Prior to versions 16.0.45 and 17.0.24 of the FreePBX framework, an authenticated local privilege escalation exists in the deprecated FreePBX startup script `amportal`. In the deprecated `amportal` utility, the lookup for the `freepbx_engine` file occurs in `/etc/asterisk/` directories. Typically, these are configured by FreePBX as writable by the **asterisk** user and any members of the **asterisk** group. This means that a member of the **asterisk** group can add their own `freepbx_engine` file in `/etc/asterisk/` and upon `amportal` executing, it would exec that file with root permissions (even though the file was created and placed by a non-root user). Version 16.0.45 and 17.0.24 contain a fix for the issue. Other mitigation strategies are also available. Confirm only trusted local OS system users are members of the `asterisk` group. Look for suspicious files in the `/etc/asterisk/` directory (via Admin -> Config Edit in the GUI, or via CLI). Double-check that `live_dangerously = no` is set (or unconfigured, as the default is **no**) in `/etc/asterisk/asterisk.conf` file. Eliminate any unsafe custom use of Asterisk dial plan applications and functions that potentially can manipulate the file system, e.g., System(), FILE(), etc.Show less

FreePBX 16 contains an authenticated remote code execution vulnerability in the API module that allows attackers with valid session credentials to execute arbitrary commands. Attackers can exploit the 'generatedocs' endpoint by crafting malicious POST requests with bash command injection to establish remote shell access.Show less

FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. Versions are vulnerable to authentication bypass when the authentication type is set to "webserver." When providing an Authorization header with an arbitrary value, a session is associated with the target user regardless of valid credentials. This issue is fixed in versions 16.0.44 and 17.0.23.Show less

FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. In versions 17.0.2.36 and above before 17.0.3, the filestore module within the Administrative interface is vulnerable to a post-authentication command injection by an authenticated known user via the testconnection -> check_ssh_connect() function. An attacker can leverage this vulnerability to obtain remote access to the system as an asterisk user. This issue is fixed in version 17.0.3.Show less

FreePBX is an open source GUI for managing Asterisk. In versions prior to 16.0.68.39 for FreePBX 16 and versions prior to 17.0.18.38 for FreePBX 17, a reflected cross-site scripting vulnerability is present on the Asterisk HTTP Status page. The Asterisk HTTP status page is exposed by FreePBX and is available by default on version 16 via any bound IP address at port 8088. By default on version 17, the binding is only to localhost IP, making it significantly less vulnerable. The vulnerability can be exploited by unauthenticated attackers to obtain cookies from logged-in users, allowing them to hijack a session of an administrative user. The theft of admin session cookies allows attackers to gain control over the FreePBX admin interface, enabling them to access sensitive data, modify system configurations, create backdoor accounts, and cause service disruption. This issue has been patched in version 16.0.68.39 for FreePBX 16 and version 17.0.18.38 for FreePBX 17.Show less

FreePBX is an open-source web-based graphical user interface. In FreePBX 15, 16, and 17, malicious connections to the Administrator Control Panel web interface can cause the uninstall function to be triggered for certain modules. This function drops the module's database tables, which is where most modules store their configuration. This vulnerability is fixed in 15.0.38, 16.0.41, and 17.0.21.Show less

FreePBX is an open-source web-based graphical user interface. From 17.0.19.11 to before 17.0.21, authenticated users of the Administrator Control Panel (ACP) can run arbitrary shell commands by maliciously changing languages of the framework module. This vulnerability is fixed in 17.0.21.Show less

FreePBX is an open-source web-based graphical user interface. FreePBX 15, 16, and 17 endpoints are vulnerable due to insufficiently sanitized user-supplied data allowing unauthenticated access to FreePBX Administrator leading to arbitrary database manipulation and remote code execution. This issue has been patched in endpoint versions 15.0.66, 16.0.89, and 17.0.3.Show less

A vulnerability was discovered in FreePBX 17.0.19.17. It does not verify the type of uploaded (valid FreePBX module) files, allowing high-privilege administrators to insert unwanted files. NOTE: the Supplier's position is that there is no risk beyond what high-privilege administrators are intentionally allowed to do.Show less

A vulnerability was found in FreePBX arimanager up to 13.0.5.3 and classified as problematic. Affected by this issue is some unknown functionality of the component Views Handler. The manipulation of the argument dataurl leads to cross site scripting. The attack may be launched remotely. Upgrading to version 13.0.5.4 is able to address this issue. The name of the patch is 199dea7cc7020d3c469a86a39fbd80f5edd3c5ab. It is recommended to upgrade the affected component. VDB-216878 is the identifier assigned to this vulnerability.Show less

A vulnerability was found in FreePBX cdr 14.0. It has been classified as critical. This affects the function ajaxHandler of the file ucp/Cdr.class.php. The manipulation of the argument limit/offset leads to sql injection. Upgrading to version 14.0.5.21 is able to address this issue. The name of the patch is f1a9eea2dfff30fb99d825bac194a676a82b9ec8. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-216771.Show less

An XSS Injection vulnerability exists in Sangoma FreePBX and PBXact 13, 14, and 15 within the Call Event Logging report screen in the cel module at the admin/config.php?display=cel URI via date fields. This affects cel through 13.0.26.9, 14.x through 14.0.2.14, and 15.x through 15.0.15.4.Show less

Multiple XSS vulnerabilities exist in the Backup & Restore module \ v14.0.10.2 through v14.0.10.7 for FreePBX, as shown at /admin/config.php?display=backup on the FreePBX Administrator web site. An attacker can modify the id parameter of the backup configuration screen and embed malicious XSS code via a link. When another user (such as an admin) clicks the link, the XSS payload will render and execute in the context of the victim user's account.Show less

An XSS Injection vulnerability exists in Sangoma FreePBX and PBXact 13, 14, and 15 within the Debug/Test page of the Superfecta module at the admin/config.php?display=superfecta URI. This affects Superfecta through 13.0.4.7, 14.x through 14.0.24, and 15.x through 15.0.2.20.Show less

In userman 13.0.76.43 through 15.0.20 in Sangoma FreePBX, XSS exists in the user management screen of the Administrator web site, i.e., the/admin/config.php?display=userman URI. An attacker with sufficient privileges can edit the Display Name of a user and embed malicious XSS code. When another user (such as an admin) visits the main User Management screen, the XSS payload will render and execute in the context of the victim user's account.Show less

In userman 13.0.76.43 through 15.0.20 in Sangoma FreePBX, XSS exists in the User Management screen of the Administrator web site. An attacker with access to the User Control Panel application can submit malicious values in some of the time/date formatting and time-zone fields. These fields are not being properly sanitized. If this is done and a user (such as an admin) visits the User Management screen and views that user's profile, the XSS payload will render and execute in the context of the victim user's account.Show less

An issue was discovered in Manager 13.x before 13.0.2.6 and 15.x before 15.0.6 before FreePBX 14.0.10.3. In the Manager module form (html\admin\modules\manager\views\form.php), an unsanitized managerdisplay variable coming from the URL is reflected in HTML, leading to XSS. It can be requested via GET request to /config.php?type=tool&display=manager.Show less
