CVE-2024-1597

pgjdbc, the PostgreSQL JDBC Driver, allows attacker to inject SQL if using PreferQueryMode=SIMPLE. Note this is not the default. In the default mode there is no vulnerability. A placeholder for a numeric value must be immediately preceded by a minus. There must be a second placeholder for a string value after the first placeholder; both must be on the same line. By constructing a matching string payload, the attacker can inject SQL to alter the query,bypassing the protections that parameterized queries bring against SQL Injection attacks. Versions before 42.7.2, 42.6.1, 42.5.5, 42.4.4, 42.3.9, and 42.2.28 are affected.

Impact

SQL injection is possible when using the non-default connection property preferQueryMode=simple in combination with application code that has a vulnerable SQL that negates a parameter value.

There is no vulnerability in the driver when using the default query mode. Users that do not override the query mode are not impacted.

Exploitation

To exploit this behavior the following conditions must be met:

1. A placeholder for a numeric value must be immediately preceded by a minus (i.e. -)
2. There must be a second placeholder for a string value after the first placeholder on the same line.
3. Both parameters must be user controlled.

The prior behavior of the driver when operating in simple query mode would inline the negative value of the first parameter and cause the resulting line to be treated as a -- SQL comment. That would extend to the beginning of the next parameter and cause the quoting of that parameter to be consumed by the comment line. If that string parameter includes a newline, the resulting text would appear unescaped in the resulting SQL.

When operating in the default extended query mode this would not be an issue as the parameter values are sent separately to the server. Only in simple query mode the parameter values are inlined into the executed SQL causing this issue.

Example

PreparedStatement stmt = conn.prepareStatement("SELECT -?, ?");
stmt.setInt(1, -1);
stmt.setString(2, "\nWHERE false --");
ResultSet rs = stmt.executeQuery();

The resulting SQL when operating in simple query mode would be:

SELECT --1,'
WHERE false --'

The contents of the second parameter get injected into the command. Note how both the number of result columns and the WHERE clause of the command have changed. A more elaborate example could execute arbitrary other SQL commands.

Patch

Problem will be patched upgrade to 42.7.2, 42.6.1, 42.5.5, 42.4.4, 42.3.9, 42.2.28, 42.2.28.jre7

The patch fixes the inlining of parameters by forcing them all to be serialized as wrapped literals. The SQL in the prior example would be transformed into:

SELECT -('-1'::int4), ('
WHERE false --')

Workarounds

Do not use the connection propertypreferQueryMode=simple. (NOTE: If you do not explicitly specify a query mode then you are using the default of extended and are not impacted by this issue.)

PostgreSQL JDBC Driver (PgJDBC for short) allows Java programs to connect to a PostgreSQL database using standard, database independent Java code. Is an open source JDBC driver written in Pure Java (Type 4), and communicates in the PostgreSQL native network protocol.
