| CVE-2012-4737 | 1 Digium | 2 Asterisk, Certified Asterisk | 2025-04-11 | N/A |
| channels/chan_iax2.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-cert7, Asterisk Digiumphones 10.x.x-digiumphones before 10.7.1-digiumphones, and Asterisk Business Edition C.3.x before C.3.7.6 does not enforce ACL rules during certain uses of peer credentials, which allows remote authenticated users to bypass intended outbound-call restrictions by leveraging the availability of these credentials. | ||||
| CVE-2012-5977 | 1 Digium | 2 Asterisk, Certified Asterisk | 2025-04-11 | N/A |
| Asterisk Open Source 1.8.x before 1.8.19.1, 10.x before 10.11.1, and 11.x before 11.1.2; Certified Asterisk 1.8.11 before 1.8.11-cert10; and Asterisk Digiumphones 10.x-digiumphones before 10.11.1-digiumphones, when anonymous calls are enabled, allow remote attackers to cause a denial of service (resource consumption) by making anonymous calls from multiple sources and consequently adding many entries to the device state cache. | ||||
| CVE-2011-1599 | 1 Digium | 1 Asterisk | 2025-04-11 | N/A |
| manager.c in the Manager Interface in Asterisk Open Source 1.4.x before 1.4.40.1, 1.6.1.x before 1.6.1.25, 1.6.2.x before 1.6.2.17.3, and 1.8.x before 1.8.3.3 and Asterisk Business Edition C.x.x before C.3.6.4 does not properly check for the system privilege, which allows remote authenticated users to execute arbitrary commands via an Originate action that has an Async header in conjunction with an Application header. | ||||
| CVE-2010-0685 | 1 Digium | 1 Asterisk | 2025-04-11 | N/A |
| The design of the dialplan functionality in Asterisk Open Source 1.2.x, 1.4.x, and 1.6.x; and Asterisk Business Edition B.x.x and C.x.x, when using the ${EXTEN} channel variable and wildcard pattern matches, allows context-dependent attackers to inject strings into the dialplan using metacharacters that are injected when the variable is expanded, as demonstrated using the Dial application to process a crafted SIP INVITE message that adds an unintended outgoing channel leg. NOTE: it could be argued that this is not a vulnerability in Asterisk, but a class of vulnerabilities that can occur in any program that uses this feature without the associated filtering functionality that is already available. | ||||
| CVE-2011-2216 | 1 Digium | 1 Asterisk | 2025-04-11 | N/A |
| reqresp_parser.c in the SIP channel driver in Asterisk Open Source 1.8.x before 1.8.4.2 does not initialize certain strings, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a malformed Contact header. | ||||
| CVE-2010-1224 | 1 Digium | 1 Asterisk | 2025-04-11 | N/A |
| main/acl.c in Asterisk Open Source 1.6.0.x before 1.6.0.25, 1.6.1.x before 1.6.1.17, and 1.6.2.x before 1.6.2.5 does not properly enforce remote host access controls when CIDR notation "/0" is used in permit= and deny= configuration rules, which causes an improper arithmetic shift and might allow remote attackers to bypass ACL rules and access services from unauthorized hosts. | ||||
| CVE-2011-2536 | 1 Digium | 1 Asterisk | 2025-04-11 | N/A |
| chan_sip.c in the SIP channel driver in Asterisk Open Source 1.4.x before 1.4.41.2, 1.6.2.x before 1.6.2.18.2, and 1.8.x before 1.8.4.4, and Asterisk Business Edition C.3.x before C.3.7.3, disregards the alwaysauthreject option and generates different responses for invalid SIP requests depending on whether the user account exists, which allows remote attackers to enumerate account names via a series of requests. | ||||
| CVE-2007-1306 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
| Asterisk 1.4 before 1.4.1 and 1.2 before 1.2.16 allows remote attackers to cause a denial of service (crash) by sending a Session Initiation Protocol (SIP) packet without a URI and SIP-version header, which results in a NULL pointer dereference. | ||||
| CVE-2006-5445 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
| Unspecified vulnerability in the SIP channel driver (channels/chan_sip.c) in Asterisk 1.2.x before 1.2.13 and 1.4.x before 1.4.0-beta3 allows remote attackers to cause a denial of service (resource consumption) via unspecified vectors that result in the creation of "a real pvt structure" that uses more resources than necessary. | ||||
| CVE-2007-4103 | 1 Digium | 2 Asterisk, Asterisk Appliance Developer Kit | 2025-04-09 | 7.5 High |
| The IAX2 channel driver (chan_iax2) in Asterisk Open 1.2.x before 1.2.23, 1.4.x before 1.4.9, and Asterisk Appliance Developer Kit before 0.6.0, when configured to allow unauthenticated calls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of calls that do not complete a 3-way handshake, which causes an ast_channel to be allocated but not released. | ||||
| CVE-2009-4055 | 1 Digium | 2 Asterisk, S800i | 2025-04-09 | N/A |
| rtp.c in Asterisk Open Source 1.2.x before 1.2.37, 1.4.x before 1.4.27.1, 1.6.0.x before 1.6.0.19, and 1.6.1.x before 1.6.1.11; Business Edition B.x.x before B.2.5.13, C.2.x.x before C.2.4.6, and C.3.x.x before C.3.2.3; and s800i 1.3.x before 1.3.0.6 allows remote attackers to cause a denial of service (daemon crash) via an RTP comfort noise payload with a long data length. | ||||
| CVE-2009-2726 | 1 Digium | 3 Asterisk, S800i, S800i Firmware | 2025-04-09 | N/A |
| The SIP channel driver in Asterisk Open Source 1.2.x before 1.2.34, 1.4.x before 1.4.26.1, 1.6.0.x before 1.6.0.12, and 1.6.1.x before 1.6.1.4; Asterisk Business Edition A.x.x, B.x.x before B.2.5.9, C.2.x before C.2.4.1, and C.3.x before C.3.1; and Asterisk Appliance s800i 1.2.x before 1.3.0.3 does not use a maximum width when invoking sscanf style functions, which allows remote attackers to cause a denial of service (stack memory consumption) via SIP packets containing large sequences of ASCII decimal characters, as demonstrated via vectors related to (1) the CSeq value in a SIP header, (2) large Content-Length value, and (3) SDP. | ||||
| CVE-2007-5358 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
| Multiple buffer overflows in the voicemail functionality in Asterisk 1.4.x before 1.4.13, when using IMAP storage, might allow (1) remote attackers to execute arbitrary code via a long combination of Content-type and Content-description headers, or (2) local users to execute arbitrary code via a long combination of astspooldir, voicemail context, and voicemail mailbox fields. NOTE: vector 2 requires write access to Asterisk configuration files. | ||||
| CVE-2007-6170 | 2 Debian, Digium | 2 Debian Linux, Asterisk | 2025-04-09 | N/A |
| SQL injection vulnerability in the Call Detail Record Postgres logging engine (cdr_pgsql) in Asterisk 1.4.x before 1.4.15, 1.2.x before 1.2.25, B.x before B.2.3.4, and C.x before C.1.0-beta6 allows remote authenticated users to execute arbitrary SQL commands via (1) ANI and (2) DNIS arguments. | ||||
| CVE-2009-3727 | 1 Digium | 3 Asterisk, Asterisknow, S800i | 2025-04-09 | N/A |
| Asterisk Open Source 1.2.x before 1.2.35, 1.4.x before 1.4.26.3, 1.6.0.x before 1.6.0.17, and 1.6.1.x before 1.6.1.9; Business Edition A.x.x, B.x.x before B.2.5.12, C.2.x.x before C.2.4.5, and C.3.x.x before C.3.2.2; AsteriskNOW 1.5; and s800i 1.3.x before 1.3.0.5 generate different error messages depending on whether a SIP username is valid, which allows remote attackers to enumerate valid usernames via multiple crafted REGISTER messages with inconsistent usernames in the URI in the To header and the Digest in the Authorization header. | ||||
| CVE-2007-6171 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
| SQL injection vulnerability in the Postgres Realtime Engine (res_config_pgsql) in Asterisk 1.4.x before 1.4.15 and C.x before C.1.0-beta6 allows remote attackers to execute arbitrary SQL commands via unknown vectors. | ||||
| CVE-2009-0871 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
| The SIP channel driver in Asterisk Open Source 1.4.22, 1.4.23, and 1.4.23.1; 1.6.0 before 1.6.0.6; 1.6.1 before 1.6.1.0-rc2; and Asterisk Business Edition C.2.3, with the pedantic option enabled, allows remote authenticated users to cause a denial of service (crash) via a SIP INVITE request without any headers, which triggers a NULL pointer dereference in the (1) sip_uri_headers_cmp and (2) sip_uri_params_cmp functions. | ||||
| CVE-2009-2651 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
| main/rtp.c in Asterisk Open Source 1.6.1 before 1.6.1.2 allows remote attackers to cause a denial of service (crash) via an RTP text frame without a certain delimiter, which triggers a NULL pointer dereference and the subsequent calculation of an invalid pointer. | ||||
| CVE-2006-5444 | 1 Digium | 1 Asterisk | 2025-04-09 | N/A |
| Integer overflow in the get_input function in the Skinny channel driver (chan_skinny.c) in Asterisk 1.0.x before 1.0.12 and 1.2.x before 1.2.13, as used by Cisco SCCP phones, allows remote attackers to execute arbitrary code via a certain dlen value that passes a signed integer comparison and leads to a heap-based buffer overflow. | ||||
| CVE-2006-2898 | 1 Digium | 1 Asterisk | 2025-04-03 | 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. | ||||
