CVE-2024-27289

Impact

SQL injection can occur when all of the following conditions are met:

1. The non-default simple protocol is used.
2. A placeholder for a numeric value must be immediately preceded by a minus.
3. There must be a second placeholder for a string value after the first placeholder; both
   must be on the same line.
4. Both parameter values must be user-controlled.

e.g.

Simple mode must be enabled:

// connection string includes "prefer_simple_protocol=true"
// or
// directly enabled in code
config.ConnConfig.PreferSimpleProtocol = true

Parameterized query:

SELECT * FROM example WHERE result=-$1 OR name=$2;

Parameter values:

$1 => -42
$2 => "foo\n 1 AND 1=0 UNION SELECT * FROM secrets; --"

Resulting query after preparation:

SELECT * FROM example WHERE result=--42 OR name= 'foo
1 AND 1=0 UNION SELECT * FROM secrets; --';

Patches

The problem is resolved in v4.18.2.

Workarounds

Do not use the simple protocol or do not place a minus directly before a placeholder.

CVE-2024-27304

Impact

SQL injection can occur if an attacker can cause a single query or bind message to exceed 4 GB in size. An integer overflow in the calculated message size can cause the one large message to be sent as multiple messages under the attacker's control.

Patches

The problem is resolved in v4.18.2 and v5.5.4.

Workarounds

Reject user input large enough to cause a single query or bind message to exceed 4 GB in size.
