EXPLOIT

Dogfood CRM version 2.0.10 contains a remote command execution vulnerability in the spell.php script used by its mail subsystem. The vulnerability arises from unsanitized user input passed via a POST request to the data parameter, which is processed by the underlying shell without adequate escaping. This allows attackers to inject arbitrary shell commands and execute them on the server. The flaw is exploitable without authentication and was discovered by researcher LSO.

path /spell.php↗

command POST data=<payload>↗

• → Monitor for POST requests to spell.php containing shell metacharacters or command injection sequences in the 'data' parameter, as this is the vulnerable injection point. ↗
• → The exploit works best with a double-reverse telnet payload; monitor for outbound telnet connections originating from the web server process following requests to spell.php. ↗
• → The vulnerability is exploitable without authentication; any unauthenticated POST to spell.php should be treated as suspicious and investigated. ↗
• → Flag use of the Metasploit module 'exploits/unix/webapp/dogfood_spell_exec' in endpoint or network telemetry as a direct indicator of exploitation attempts against this CVE. ↗

• · Character restrictions in the injection context limit payload options; only certain shell command constructs will succeed, making the double-reverse telnet payload the most reliable exploitation method. ↗
• · This vulnerability is confirmed to affect Dogfood CRM version 2.0.10 only; scope detection rules accordingly. ↗
