| CVE-2022-42706 | 1 Sangoma | 2 Asterisk, Certified Asterisk | 2024-11-21 | N/A | 4.9 MEDIUM |
| 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. | |||||
| CVE-2022-42705 | 1 Sangoma | 2 Asterisk, Certified Asterisk | 2024-11-21 | N/A | 6.5 MEDIUM |
| 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. | |||||
| CVE-2022-37325 | 1 Sangoma | 1 Asterisk | 2024-11-21 | N/A | 7.5 HIGH |
| 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. | |||||
| CVE-2022-23608 | 4 Asterisk, Debian, Sangoma and 1 more | 4 Certified Asterisk, Debian Linux, Asterisk and 1 more | 2024-11-21 | 7.5 HIGH | 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 | 2024-11-21 | 6.4 MEDIUM | 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 | 2024-11-21 | 9.3 HIGH | 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-2020-28327 | 2 Digium, Sangoma | 2 Certified Asterisk, Asterisk | 2024-11-21 | 2.1 LOW | 5.3 MEDIUM |
| A res_pjsip_session crash was discovered in Asterisk Open Source 13.x before 13.37.1, 16.x before 16.14.1, 17.x before 17.8.1, and 18.x before 18.0.1. and Certified Asterisk before 16.8-cert5. Upon receiving a new SIP Invite, Asterisk did not return the created dialog locked or referenced. This caused a gap between the creation of the dialog object, and its next use by the thread that created it. Depending on some off-nominal circumstances and timing, it was possible for another thread to free said dialog in this gap. Asterisk could then crash when the dialog object, or any of its dependent objects, were dereferenced or accessed next by the initial-creation thread. Note, however, that this crash can only occur when using a connection-oriented protocol (e.g., TCP or TLS, but not UDP) for SIP transport. Also, the remote client must be authenticated, or Asterisk must be configured for anonymous calling. | |||||
| CVE-2020-28242 | 4 Asterisk, Debian, Fedoraproject and 1 more | 4 Certified Asterisk, Debian Linux, Fedora and 1 more | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Asterisk Open Source 13.x before 13.37.1, 16.x before 16.14.1, 17.x before 17.8.1, and 18.x before 18.0.1 and Certified Asterisk before 16.8-cert5. If Asterisk is challenged on an outbound INVITE and the nonce is changed in each response, Asterisk will continually send INVITEs in a loop. This causes Asterisk to consume more and more memory since the transaction will never terminate (even if the call is hung up), ultimately leading to a restart or shutdown of Asterisk. Outbound authentication must be configured on the endpoint for this to occur. | |||||
| CVE-2018-12228 | 1 Sangoma | 1 Asterisk | 2024-11-21 | 6.8 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Asterisk Open Source 15.x before 15.4.1. When connected to Asterisk via TCP/TLS, if the client abruptly disconnects, or sends a specially crafted message, then Asterisk gets caught in an infinite loop while trying to read the data stream. This renders the system unusable. | |||||
| CVE-2017-9358 | 2 Asterisk, Sangoma | 2 Certified Asterisk, Asterisk | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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). | |||||
| CVE-2012-2948 | 2 Asterisk, Sangoma | 3 Certified Asterisk, Open Source, Asterisk | 2024-11-21 | 4.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2012-2186 | 2 Asterisk, Sangoma | 5 Business Edition, Certified Asterisk, Digiumphones and 2 more | 2024-11-21 | 9.0 HIGH | N/A |
| 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. | |||||

| CVE-2009-2346 | 2 Asterisk, Sangoma | 5 Appliance S800i, Asterisk, Open Source and 2 more | 2024-11-21 | 7.8 HIGH | N/A |
| 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. | |||||
| CVE-2024-49215 | 1 Sangoma | 2 Asterisk, Certified Asterisk | 2024-10-24 | N/A | 7.8 HIGH |
| An issue was discovered in Sangoma Asterisk through 18.20.0, 19.x and 20.x through 20.5.0, and 21.x through 21.0.0, and Certified Asterisk through 18.9-cert5. In manager.c, the functions action_getconfig() and action_getconfigJson() do not process the input file path, resulting in a path traversal vulnerability. In versions without the restrictedFile() function, no processing is done on the input path. In versions with the restrictedFile() function, path traversal is not processed. | |||||
