- →Detect AMI traffic containing 'Action: Originate' combined with a 'Data:' field referencing /tmp/ — this pattern matches the PoC exploit for CVE-2019-18610 where a crafted Originate AMI request is used to execute arbitrary system commands.
- →The vulnerability is in manager.c; monitor AMI sessions for authenticated users without 'system' authorization issuing Originate requests with shell command payloads in the Data field. ↗
- ·The Snort/ET rule is described as PoC-based, meaning it targets known proof-of-concept exploit patterns (specifically /tmp/ paths in the Data field) and may not catch all variants of exploitation.
- ·The vulnerability affects Sangoma Asterisk through 13.x, 16.x, 17.x and Certified Asterisk 13.21 through 13.21-cert4; ensure patching to at least 1:16.10.0~dfsg-1 (Debian) or equivalent upstream fix per AST-2019-007. ↗
