- →Exploit targets HTTP GET requests to /mnt_ping.cgi with URL-encoded shell metacharacter '|3b|' (semicolon) injected into the pingAddr parameter, enabling OS command injection as root. ↗
- →The URI pattern /mnt_ping.cgi?isSubmit=1&addrType=3&pingAddr=|3b| (where |3b| is URL-encoded semicolon) should be treated as a high-confidence exploit indicator; match at URI start (startswith).
- →This exploit is associated with the Mirai variant EchoBot, which weaponized this CVE alongside CVE-2019-18396 against IoT devices.
- →Monitor both inbound (ET sid:2029155) and outbound (ET sid:2029154) HTTP flows for the exploit URI pattern to detect both incoming attacks and potentially compromised internal hosts beaconing out.
- ·The Snort/Suricata rules carry only 'confidence Medium' metadata, meaning false positives are possible; tune deployment to perimeter sensors as indicated.

Unlike other Mirai variants, this particular variant stands out for the sheer number of exploits it incorporates, with the latest version having a total of 71 unique exploits, 13 of which haven’t been seen exploited in the wild until now, ranging from extremely old CVEs from as long back as 2003, to recent vulnerabilities made public as recently as early December 2019. Based on this seemingly odd choice, one could risk a guess that the attackers could potentially be aiming for the sweet sp
