CVE-1999-1228 describes a vulnerability in various modems, including models from Diamond, Logicode, and US Robotics, where a missing or zero-configured guard time allows remote attackers to execute arbitrary modem commands. This is achieved by injecting the "+++" escape sequence into various network traffic, such as ICMP packets or email subjects. The vulnerability carries a CVSS score of 7.5 (HIGH), indicating a network-based attack with low complexity that could lead to partial compromise of confidentiality, integrity, and availability. Despite its age and potential impact, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
