An issue was discovered in certain Oi third-party firmware that may be installed on Technicolor TD5130v2 devices. A Command Injection in the Ping module in the Web Interface in OI_Fw_V20 allows remote attackers to execute arbitrary OS commands in the pingAddr parameter to mnt_ping.cgi. NOTE: This may overlap CVE-2017–14127.

- →Exploit targets HTTP POST to /mnt_ping.cgi with command injection payload in the 'pingAddr' parameter using semicolon (;) as command separator ↗
- →In-the-wild exploitation (e.g., by Mirai variant EchoBot) uses GET requests to /mnt_ping.cgi with URL-encoded semicolon (|3b|) in pingAddr parameter
- →Monitor both inbound and outbound HTTP traffic for the URI pattern /mnt_ping.cgi?isSubmit=1&addrType=3&pingAddr= as covered by ET rules sid:2029155 (inbound) and sid:2029154 (outbound)
- →Exploitation linked to Mirai variant EchoBot; correlate with known Mirai botnet IoCs when this CVE is triggered
- ·The vulnerability exists only in third-party Oi firmware (OI_Fw_V20) installed on Technicolor TD5130v2 devices, not in stock Technicolor firmware ↗
- ·This CVE may overlap with CVE-2017-14127, so detections should consider both CVEs together (as reflected in the ET Snort rules referencing both) ↗

Since the discovery of the Mirai variant using the binary name ECHOBOT in May 2019, it has resurfaced from time to time, using new infrastructure, and more remarkably, adding to the list of vulnerabilities it scans for, as a means to increase its attack surface with each evolution.
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
