Improper neutralization of quoting syntax in PostgreSQL libpq
functions PQescapeLiteral(), PQescapeIdentifier(), PQescapeString(), and
PQescapeStringConn() allows a database input provider to achieve SQL
injection in certain usage patterns. Specifically, SQL injection requires the
application to use the function result to construct input to psql, the
PostgreSQL interactive terminal. Similarly, improper neutralization of quoting
syntax in PostgreSQL command line utility programs allows a source of command
line arguments to achieve SQL injection when client_encoding
is BIG5 and
server_encoding
is one of EUC_TW or MULE_INTERNAL. Versions before PostgreSQL 17.3, 16.7,
15.11, 14.16, and 13.19 are affected.
The PostgreSQL project thanks Stephen Fewer, Principal Security Researcher, Rapid7 for reporting this problem.
