| 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. | |||||
| CVE-2023-49786 | 2 Digium, Sangoma | 2 Asterisk, Certified Asterisk | 2024-02-28 | N/A | 5.9 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; 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-2023-37457 | 2 Digium, Sangoma | 2 Asterisk, Certified Asterisk | 2024-02-28 | N/A | 8.2 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-2023-49294 | 2 Digium, Sangoma | 2 Asterisk, Certified Asterisk | 2024-02-28 | N/A | 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, 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-2022-42706 | 1 Sangoma | 2 Asterisk, Certified Asterisk | 2024-02-28 | 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 | 2024-02-28 | 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. | |||||
