CVSS v3.1 |
| 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. |
| 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.

| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| FreePBX 2.5.1, and other 2.4.x, 2.5.x, and pre-release 2.6.x versions, generates different error messages for a failed login attempt depending on whether the user account exists, which allows remote attackers to enumerate valid usernames. |
| Multiple race conditions in WANPIPE before 3.3.6 have unknown impact and attack vectors related to "bri restart logic." |
| Multiple cross-site scripting (XSS) vulnerabilities in FreePBX 2.5.1, and other 2.4.x, 2.5.x, and pre-release 2.6.x versions, allow remote attackers to inject arbitrary web script or HTML via the (1) display parameter to reports.php, the (2) order and (3) extdisplay parameters to config.php, and the (4) sort parameter to recordings/index.php. NOTE: some of these details are obtained from third party information. |
