Detection & IOCsextracted from sources · hover to see the quote
- →Detect exploitation attempts targeting card_scan_decoder.php with backtick-wrapped command injection in the 'door' GET parameter (e.g., door=`<cmd>`) and No=251 ↗
- →Check for HTTP 200 responses from card_scan_decoder.php that include 'PHP/5.6.23' in the response body as a vulnerability confirmation fingerprint used by the Metasploit module ↗
- →Alert on SSH login attempts to Linear eMerge E3 devices using username 'root' and password 'davestyle' on port 22, which is the hardcoded default credential used by the exploit ↗
- →The vulnerability is an unsanitized exec() PHP function call; monitor web server logs on Linear eMerge E3 devices for GET requests to card_scan_decoder.php containing backtick or shell metacharacters in the 'door' parameter ↗
- ·The affected version is specifically 4.6.07 running on GNU/Linux 3.14.54 (ARMv7 rev 10) with Lighttpd 1.4.40 and PHP/5.6.23; the Metasploit check method fingerprints this exact PHP version string ↗
- ·The exploit achieves root-level command execution; post-exploitation interactive shell is obtained via SSH with hardcoded credentials, indicating a separate hardcoded credential vulnerability (CVE-2019-7265) distinct from the command injection (CVE-2019-7256) ↗
