Directory Traversal

Asterisk is vulnerable to Directory Traversal. The vulnerability arises because it allows the reading of any arbitrary file, even when the livedangerously setting is not enabled.This allows arbitrary files to be read...

Denial Of Service

asterisk:sid is vulnerable to denial of service. The vulnerability due to a race condition in the hello handshake phase of the DTLS protocol when handling DTLS-SRTP for media setup. It allows an attacker can be done continuously, thus denying new DTLS-SRTP encrypted calls which can leads to denia...

The vulnerability of the AMI interface of Asterisk management systems for IP-telephony devices allows a hacker to gain access to and read arbitrary files.

The vulnerability of the AMI interface of Asterisk management systems for IP-telephony and Certified Asterisk is related to incorrect restrictions on the path name to the restricted directory. Exploiting this vulnerability could allow an attacker, operating remotely, to gain read access to...

The vulnerability of the implementations of DTLS (Datagram Transport Layer Security) and SRTP protocols in Asterisk IP-telephony management systems and Certified Asterisk allows a attacker to induce a service failure.

The vulnerability of DTLS and SRTP protocols for Asterisk IP-telephony systems and Certified Asterisk arises from the behavior of the message processing mechanism during ClientHello messages. Exploiting this vulnerability allows a malicious actor to cause service failures...

The vulnerability of the PJSIP_HEADER() function in Asterisk IP telephony management systems and Certified Asterisk versions allows attackers to trigger a service failure.

The vulnerability of the PJSIPHEADER function in Asterisk IP telephony systems and Certified Asterisk is related to the operation of writing data beyond the buffer in memory when processing the update argument. Exploiting this vulnerability can allow a malicious actor to cause service failures...

Asterisk Buffer Overflow Vulnerability (CNVD-2023-9903086)

Asterisk is a software for PBX systems that runs on Linux and supports IP calls using SIP, IAX, and H323 protocols. Asterisk suffers from a buffer overflow vulnerability, which stems from the "update" function of the PJSIPHEADER dialplan function that may exceed the available buffer space for...
