CVSS v3.1 |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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.

| Sangoma FreePBX 1805 through 2203 on Linux contains hardcoded credentials for the Asterisk REST Interface (ARI), which allows remote attackers to reconfigure Asterisk and make external and internal calls via HTTP and WebSocket requests sent to the API. |
| A buffer overflow in the the Sangoma IMG2020 HTTP server through 2.3.9.6 allows an unauthenticated user to achieve remote code execution. |
| An issue was discovered in Sangoma Asterisk through 16.28, 17 and 18 through 18.14, 19 through 19.6, and certified through 18.9-cert1. GetConfig, via Asterisk Manager Interface, allows a connected application to access files outside of the asterisk configuration directory, aka Directory Traversal. |
| A use-after-free in res_pjsip_pubsub.c in Sangoma Asterisk 16.28, 18.14, 19.6, and certified/18.9-cert2 may allow a remote authenticated attacker to crash Asterisk (denial of service) by performing activity on a subscription via a reliable transport at the same time that Asterisk is also performing activity on that subscription. |
| In Sangoma Asterisk through 16.28.0, 17.x and 18.x through 18.14.0, and 19.x through 19.6.0, an incoming Setup message to addons/ooh323c/src/ooq931.c with a malformed Calling or Called Party IE can cause a crash. |
| A memory exhaustion vulnerability exists in Asterisk Open Source 13.x before 13.15.1 and 14.x before 14.4.1 and Certified Asterisk 13.13 before 13.13-cert4, which can be triggered by sending specially crafted SCCP packets causing an infinite loop and leading to memory exhaustion (by message logging in that loop). |
| Sangoma NetBorder / Vega Session Controller before 2.3.12-80-GA allows remote attackers to execute arbitrary commands via the web interface. |
| htdocs_ari/includes/login.php in the ARI Framework module/Asterisk Recording Interface (ARI) in FreePBX before 2.9.0.9, 2.10.x, and 2.11 before 2.11.1.5 allows remote attackers to execute arbitrary code via the ari_auth cookie, related to the PHP unserialize function, as exploited in the wild in September 2014. |
| Incomplete blacklist vulnerability in main/manager.c in Asterisk Open Source 1.8.x before 1.8.15.1 and 10.x before 10.7.1, Certified Asterisk 1.8.11 before 1.8.11-cert6, Asterisk Digiumphones 10.x.x-digiumphones before 10.7.1-digiumphones, and Asterisk Business Edition C.3.x before C.3.7.6 allows remote authenticated users to execute arbitrary commands by leveraging originate privileges and providing an ExternalIVR value in an AMI Originate action. |
| Directory traversal vulnerability in page.recordings.php in the System Recordings component in the configuration interface in FreePBX 2.8.0 and earlier allows remote authenticated administrators to create arbitrary files via a .. (dot dot) in the usersnum parameter to admin/config.php, as demonstrated by creating a .php file under the web root. |
| admin/libraries/view.functions.php in FreePBX 2.9 before 2.9.0.14, 2.10 before 2.10.1.15, 2.11 before 2.11.0.23, and 12 before 12.0.1alpha22 does not restrict the set of functions accessible to the API handler, which allows remote attackers to execute arbitrary PHP code via the function and args parameters to admin/config.php. |
| The callme_startcall function in recordings/misc/callme_page.php in FreePBX 2.9, 2.10, and earlier allows remote attackers to execute arbitrary commands via the callmenum parameter in a c action. |
| Multiple cross-site scripting (XSS) vulnerabilities in FreePBX 2.9 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) context parameter to panel/index_amp.php or (2) panel/dhtml/index.php; (3) clid or (4) clidname parameters to panel/flash/mypage.php; (5) PATH_INFO to admin/views/freepbx_reload.php; or (6) login parameter to recordings/index.php. |
| chan_skinny.c in the Skinny (aka SCCP) channel driver in Certified Asterisk 1.8.11-cert before 1.8.11-cert2 and Asterisk Open Source 1.8.x before 1.8.12.1 and 10.x before 10.4.1 allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by closing a connection in off-hook mode. |
