| CVE-2006-4345 | 1 Digium | 1 Asterisk | 2024-11-21 | 7.5 HIGH | N/A |
| Stack-based buffer overflow in channels/chan_mgcp.c in MGCP in Asterisk 1.0 through 1.2.10 allows remote attackers to execute arbitrary code via a crafted audit endpoint (AUEP) response. | |||||
| CVE-2006-2898 | 1 Digium | 1 Asterisk | 2024-11-21 | 7.5 HIGH | N/A |
| The IAX2 channel driver (chan_iax2) for Asterisk 1.2.x before 1.2.9 and 1.0.x before 1.0.11 allows remote attackers to cause a denial of service (crash) and execute arbitrary code via truncated IAX 2 (IAX2) video frames, which bypasses a length check and leads to a buffer overflow involving negative length check. NOTE: the vendor advisory claims that only a DoS is possible, but the original researcher is reliable. | |||||
| CVE-2006-1827 | 1 Digium | 1 Asterisk | 2024-11-21 | 6.4 MEDIUM | N/A |
| Integer signedness error in format_jpeg.c in Asterisk 1.2.6 and earlier allows remote attackers to execute arbitrary code via a length value that passes a length check as a negative number, but triggers a buffer overflow when it is used as an unsigned length. | |||||
| CVE-2005-3559 | 1 Digium | 1 Asterisk | 2024-11-21 | 5.0 MEDIUM | N/A |
| Directory traversal vulnerability in vmail.cgi in Asterisk 1.0.9 through 1.2.0-beta1 allows remote attackers to access WAV files via a .. (dot dot) in the folder parameter. | |||||
| CVE-2005-2081 | 1 Digium | 1 Asterisk | 2024-11-20 | 5.0 MEDIUM | N/A |
| Stack-based buffer overflow in the function that parses commands in Asterisk 1.0.7, when the 'write = command' option is enabled, allows remote attackers to execute arbitrary code via a command that has two double quotes followed by a tab character. | |||||
| CVE-2003-0779 | 1 Digium | 1 Asterisk | 2024-11-20 | 7.5 HIGH | N/A |
| SQL injection vulnerability in the Call Detail Record (CDR) logging functionality for Asterisk allows remote attackers to execute arbitrary SQL via a CallerID string. | |||||
| CVE-2003-0761 | 1 Digium | 1 Asterisk | 2024-11-20 | 7.5 HIGH | N/A |
| Buffer overflow in the get_msg_text of chan_sip.c in the Session Initiation Protocol (SIP) protocol implementation for Asterisk releases before August 15, 2003, allows remote attackers to execute arbitrary code via certain (1) MESSAGE or (2) INFO requests. | |||||
| 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-2021-46837 | 3 Asterisk, Debian, Digium | 3 Certified Asterisk, Debian Linux, Asterisk | 2024-02-28 | N/A | 6.5 MEDIUM |
| res_pjsip_t38 in Sangoma Asterisk 16.x before 16.16.2, 17.x before 17.9.3, and 18.x before 18.2.2, and Certified Asterisk before 16.8-cert7, allows an attacker to trigger a crash by sending an m=image line and zero port in a response to a T.38 re-invite initiated by Asterisk. This is a re-occurrence of the CVE-2019-15297 symptoms but not for exactly the same reason. The crash occurs because there is an append operation relative to the active topology, but this should instead be a replace operation. | |||||
| CVE-2022-26651 | 2 Debian, Digium | 3 Debian Linux, Asterisk, Certified Asterisk | 2024-02-28 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in Asterisk through 19.x and Certified Asterisk through 16.8-cert13. The func_odbc module provides possibly inadequate escaping functionality for backslash characters in SQL queries, resulting in user-provided data creating a broken SQL query or possibly a SQL injection. This is fixed in 16.25.2, 18.11.2, and 19.3.2, and 16.8-cert14. | |||||
| CVE-2022-26499 | 2 Debian, Digium | 2 Debian Linux, Asterisk | 2024-02-28 | 6.4 MEDIUM | 9.1 CRITICAL |
| An SSRF issue was discovered in Asterisk through 19.x. When using STIR/SHAKEN, it's possible to send arbitrary requests (such as GET) to interfaces such as localhost by using the Identity header. This is fixed in 16.25.2, 18.11.2, and 19.3.2. | |||||
| CVE-2022-26498 | 2 Debian, Digium | 2 Debian Linux, Asterisk | 2024-02-28 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Asterisk through 19.x. When using STIR/SHAKEN, it is possible to download files that are not certificates. These files could be much larger than what one would expect to download, leading to Resource Exhaustion. This is fixed in 16.25.2, 18.11.2, and 19.3.2. | |||||
