| CVE-2024-57520 | 1 Sangoma | 1 Asterisk | 2025-11-06 | 9.8 Critical |
| Insecure Permissions vulnerability in asterisk v22 allows a remote attacker to execute arbitrary code via the action_createconfig function. NOTE: this is disputed by the Supplier because the impact is limited to creating empty files outside of the Asterisk product directory (aka directory traversal) and the attack can only be performed by a privileged user who has the ability to manage the configuration. | ||||
| CVE-2022-23608 | 4 Asterisk, Debian, Sangoma and 1 more | 4 Certified Asterisk, Debian Linux, Asterisk and 1 more | 2025-11-04 | 8.1 High |
| PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In versions up to and including 2.11.1 when in a dialog set (or forking) scenario, a hash key shared by multiple UAC dialogs can potentially be prematurely freed when one of the dialogs is destroyed . The issue may cause a dialog set to be registered in the hash table multiple times (with different hash keys) leading to undefined behavior such as dialog list collision which eventually leading to endless loop. A patch is available in commit db3235953baa56d2fb0e276ca510fefca751643f which will be included in the next release. There are no known workarounds for this issue. | ||||
| CVE-2022-21723 | 4 Asterisk, Debian, Sangoma and 1 more | 4 Certified Asterisk, Debian Linux, Asterisk and 1 more | 2025-11-04 | 9.1 Critical |
| PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In versions 2.11.1 and prior, parsing an incoming SIP message that contains a malformed multipart can potentially cause out-of-bound read access. This issue affects all PJSIP users that accept SIP multipart. The patch is available as commit in the `master` branch. There are no known workarounds. | ||||
| CVE-2021-37706 | 4 Asterisk, Debian, Sangoma and 1 more | 4 Certified Asterisk, Debian Linux, Asterisk and 1 more | 2025-11-04 | 7.3 High |
| PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In affected versions if the incoming STUN message contains an ERROR-CODE attribute, the header length is not checked before performing a subtraction operation, potentially resulting in an integer underflow scenario. This issue affects all users that use STUN. A malicious actor located within the victim’s network may forge and send a specially crafted UDP (STUN) message that could remotely execute arbitrary code on the victim’s machine. Users are advised to upgrade as soon as possible. There are no known workarounds. | ||||
| CVE-2024-42491 | 2 Asterisk, Sangoma | 3 Asterisk, Asterisk, Certified Asterisk | 2025-11-03 | 5.7 Medium |
| Asterisk is an open-source private branch exchange (PBX). Prior to versions 18.24.3, 20.9.3, and 21.4.3 of Asterisk and versions 18.9-cert12 and 20.7-cert2 of certified-asterisk, if Asterisk attempts to send a SIP request to a URI whose host portion starts with `.1` or `[.1]`, and res_resolver_unbound is loaded, Asterisk will crash with a SEGV. To receive a patch, users should upgrade to one of the following versions: 18.24.3, 20.9.3, 21.4.3, certified-18.9-cert12, certified-20.7-cert2. Two workarounds are available. Disable res_resolver_unbound by setting `noload = res_resolver_unbound.so` in modules.conf, or set `rewrite_contact = yes` on all PJSIP endpoints. NOTE: This may not be appropriate for all Asterisk configurations. | ||||
| CVE-2025-47780 | 2 Asterisk, Sangoma | 4 Asterisk, Certified Asterisk, Asterisk and 1 more | 2025-11-03 | 7.8 High |
| Asterisk is an open-source private branch exchange (PBX). Prior to versions 18.26.2, 20.14.1, 21.9.1, and 22.4.1 of Asterisk and versions 18.9-cert14 and 20.7-cert5 of certified-asterisk, trying to disallow shell commands to be run via the Asterisk command line interface (CLI) by configuring `cli_permissions.conf` (e.g. with the config line `deny=!*`) does not work which could lead to a security risk. If an administrator running an Asterisk instance relies on the `cli_permissions.conf` file to work and expects it to deny all attempts to execute shell commands, then this could lead to a security vulnerability. Versions 18.26.2, 20.14.1, 21.9.1, and 22.4.1 of Asterisk and versions 18.9-cert14 and 20.7-cert5 of certified-asterisk fix the issue. | ||||
| CVE-2025-47779 | 2 Asterisk, Sangoma | 4 Asterisk, Certified Asterisk, Asterisk and 1 more | 2025-11-03 | 7.7 High |
| Asterisk is an open-source private branch exchange (PBX). Prior to versions 18.26.2, 20.14.1, 21.9.1, and 22.4.1 of Asterisk and versions 18.9-cert14 and 20.7-cert5 of certified-asterisk, SIP requests of the type MESSAGE (RFC 3428) authentication do not get proper alignment. An authenticated attacker can spoof any user identity to send spam messages to the user with their authorization token. Abuse of this security issue allows authenticated attackers to send fake chat messages can be spoofed to appear to come from trusted entities. Even administrators who follow Security best practices and Security Considerations can be impacted. Therefore, abuse can lead to spam and enable social engineering, phishing and similar attacks. Versions 18.26.2, 20.14.1, 21.9.1, and 22.4.1 of Asterisk and versions 18.9-cert14 and 20.7-cert5 of certified-asterisk fix the issue. | ||||
| CVE-2025-54995 | 2 Asterisk, Sangoma | 3 Asterisk, Asterisk, Certified Asterisk | 2025-11-03 | 6.5 Medium |
| Asterisk is an open source private branch exchange and telephony toolkit. Prior to versions 18.26.4 and 18.9-cert17, RTP UDP ports and internal resources can leak due to a lack of session termination. This could result in leaks and resource exhaustion. This issue has been patched in versions 18.26.4 and 18.9-cert17. | ||||
| CVE-2025-1131 | 2 Asterisk, Sangoma | 3 Asterisk, Asterisk, Certified Asterisk | 2025-11-03 | 7.8 High |
| A local privilege escalation vulnerability exists in the safe_asterisk script included with the Asterisk toolkit package. When Asterisk is started via this script (common in SysV init or FreePBX environments), it sources all .sh files located in /etc/asterisk/startup.d/ as root, without validating ownership or permissions. Non-root users with legitimate write access to /etc/asterisk can exploit this behaviour by placing malicious scripts in the startup.d directory, which will then execute with root privileges upon service restart. | ||||
| CVE-2025-57819 | 2 Freepbx, Sangoma | 2 Freepbx, Freepbx | 2025-10-24 | 9.8 Critical |
| 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. | ||||
| CVE-2025-57767 | 2 Asterisk, Sangoma | 2 Asterisk, Asterisk | 2025-10-20 | 7.5 High |
| Asterisk is an open source private branch exchange and telephony toolkit. Prior to versions 20.15.2, 21.10.2, and 22.5.2, if a SIP request is received with an Authorization header that contains a realm that wasn't in a previous 401 response's WWW-Authenticate header, or an Authorization header with an incorrect realm was received without a previous 401 response being sent, the get_authorization_header() function in res_pjsip_authenticator_digest will return a NULL. This wasn't being checked before attempting to get the digest algorithm from the header which causes a SEGV. This issue has been patched in versions 20.15.2, 21.10.2, and 22.5.2. There are no workarounds. | ||||
| CVE-2025-55211 | 2 Freepbx, Sangoma | 2 Freepbx, Freepbx | 2025-10-17 | 8.8 High |
| 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. | ||||
| CVE-2025-59056 | 2 Freepbx, Sangoma | 2 Freepbx, Freepbx | 2025-10-17 | 7.5 High |
| 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. | ||||
| CVE-2024-53564 | 2 Coalescent Systems, Sangoma | 2 Freepbx, Freepbx | 2025-09-23 | 2.2 Low |
| 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. | ||||
| CVE-2024-35190 | 2 Asterisk, Sangoma | 2 Asterisk, Asterisk | 2025-08-26 | 5.8 Medium |
| Asterisk is an open source private branch exchange and telephony toolkit. After upgrade to 18.23.0, ALL unauthorized SIP requests are identified as PJSIP Endpoint of local asterisk server. This vulnerability is fixed in 18.23.1, 20.8.1, and 21.3.1. | ||||
| CVE-2025-32105 | 1 Sangoma | 2 Img2020, Img2020 Firmware | 2025-06-18 | 9.8 Critical |
| A buffer overflow in the the Sangoma IMG2020 HTTP server through 2.3.9.6 allows an unauthenticated user to achieve remote code execution. | ||||
