Title
Pi-hole FTL affected by Remote Code Execution (RCE) via dns.upstreams Newline Injection
Summary
FTLDNS (pihole-FTL) provides an interactive API and also generates statistics for Pi-hole's Web interface. From 6.0 to before 6.6, the Pi-hole FTL engine contains a Remote Code Execution (RCE) vulnerability in the upstream DNS servers configuration parameter (dns.upstreams). This vulnerability allows an authenticated attacker to inject arbitrary dnsmasq configuration directives through newline characters, ultimately achieving command execution on the underlying system. This vulnerability is fixed in 6.6.
CWE
  • CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
  • CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')
