| CVE-2022-42705 | 1 Sangoma | 2 Asterisk, Certified Asterisk | 2024-08-03 | 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-2022-42706 | 1 Sangoma | 2 Asterisk, Certified Asterisk | 2024-08-03 | 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-2022-37325 | 1 Sangoma | 1 Asterisk | 2024-08-03 | 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 | 2024-08-03 | 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 | 2024-08-03 | 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-2023-49786 | 2 Digium, Sangoma | 2 Asterisk, Certified Asterisk | 2024-08-02 | 7.5 High |
| 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. | ||||
| CVE-2023-49294 | 2 Digium, Sangoma | 2 Asterisk, Certified Asterisk | 2024-08-02 | 4.9 Medium |
| 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. | ||||
| CVE-2023-37457 | 2 Digium, Sangoma | 2 Asterisk, Certified Asterisk | 2024-08-02 | 7.5 High |
| 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. | ||||
| CVE-2023-26567 | 1 Sangoma | 1 Freepbx Linux 7 | 2024-08-02 | 8.1 High |
| Sangoma FreePBX 1805 through 2302 (when obtained as a ,.ISO file) places AMPDBUSER, AMPDBPASS, AMPMGRUSER, and AMPMGRPASS in the list of global variables. This exposes cleartext authentication credentials for the Asterisk Database (MariaDB/MySQL) and Asterisk Manager Interface. For example, an attacker can make a /ari/asterisk/variable?variable=AMPDBPASS API call. | ||||
