Ensure pg_hba.conf does not use 'trust' or 'password' authentication

КритичнаНиво 1Аутоматскаpostgres

Опис

trust allows login without any credential and password sends the password in clear text. The CIS PostgreSQL 18 Benchmark covers pg_hba.conf only through the manual checks 5.3/5.4; this rule automates that part by reading pg_hba_file_rules (superuser). Runs psql as ${PGUSER:-postgres} against ${PGDATABASE:-postgres}; set PGHOST/PGPORT and use ~/.pgpass (not PGPASSWORD, see 1.6/1.7) when peer authentication is not available.

Како се проверава

Метод провере: SQL упит

sql_query

out=$(psql -X -U "${PGUSER:-postgres}" -d "${PGDATABASE:-postgres}" -tAc "SELECT count(*) FROM pg_hba_file_rules WHERE auth_method IN ('trust','password')" 2>/dev/null) || exit 1; printf '%s\n' "$out"

Очекивани излаз: 0

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

Replace trust/password entries in pg_hba.conf with scram-sha-256 (or peer for local administrative sockets), then SELECT pg_reload_conf();
