CVSS v3.1 |
| 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. |
| Sangoma NetBorder / Vega Session Controller before 2.3.12-80-GA allows remote attackers to execute arbitrary commands via the web interface. |
| 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). |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| Multiple race conditions in WANPIPE before 3.3.6 have unknown impact and attack vectors related to "bri restart logic." |
| Multiple cross-site request forgery (CSRF) 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 hijack the authentication of admins for requests that create a new admin account or have unspecified other impact. |
| 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. |
| 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. |
| The IAX2 protocol implementation in Asterisk Open Source 1.2.x before 1.2.35, 1.4.x before 1.4.26.2, 1.6.0.x before 1.6.0.15, and 1.6.1.x before 1.6.1.6; Business Edition B.x.x before B.2.5.10, C.2.x before C.2.4.3, and C.3.x before C.3.1.1; and s800i 1.3.x before 1.3.0.3 allows remote attackers to cause a denial of service (call-number exhaustion) by initiating many IAX2 message exchanges, a related issue to CVE-2008-3263. |
| Asterisk is an open source private branch exchange and telephony toolkit. In Asterisk prior to versions 18.20.1, 20.5.1, and 21.0.1; as well as certified-asterisk prior to 18.9-cert6; Asterisk is susceptible to a DoS due to a race condition in the hello handshake phase of the DTLS protocol when handling DTLS-SRTP for media setup. This attack can be done continuously, thus denying new DTLS-SRTP encrypted calls during the attack. Abuse of this vulnerability may lead to a massive Denial of Service on vulnerable Asterisk servers for calls that rely on DTLS-SRTP. Commit d7d7764cb07c8a1872804321302ef93bf62cba05 contains a fix, which is part of versions 18.20.1, 20.5.1, 21.0.1, amd 18.9-cert6. |
| Asterisk is an open source private branch exchange and telephony toolkit. In Asterisk prior to versions 18.20.1, 20.5.1, and 21.0.1, as well as certified-asterisk prior to 18.9-cert6, it is possible to read any arbitrary file even when the `live_dangerously` is not enabled. This allows arbitrary files to be read. Asterisk versions 18.20.1, 20.5.1, and 21.0.1, as well as certified-asterisk prior to 18.9-cert6, contain a fix for this issue. |
| Asterisk is an open source private branch exchange and telephony toolkit. In Asterisk versions 18.20.0 and prior, 20.5.0 and prior, and 21.0.0; as well as ceritifed-asterisk 18.9-cert5 and prior, the 'update' functionality of the PJSIP_HEADER dialplan function can exceed the available buffer space for storing the new value of a header. By doing so this can overwrite memory or cause a crash. This is not externally exploitable, unless dialplan is explicitly written to update a header based on data from an outside source. If the 'update' functionality is not used the vulnerability does not occur. A patch is available at commit a1ca0268254374b515fa5992f01340f7717113fa. |
| 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. |
