CVE-2018-13450 (PHP, published 2018-07-08T16:29Z)
Description: value: SQL injection vulnerability in product/card.php in Dolibarr ERP/CRM version 7.0.3 allows remote attackers to execute arbitrary SQL commands via the status_batch parameter.
Severity: HIGH (CVSS v3 base score: 9.8)
Weakness: CWE-89 \u2014 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Vulnerable code:

 * @param		string		$type		1=GET, 0=POST, 2=PHP_SELF
	if ($type == 1)
		$inj += preg_match('/updatexml\(/i',	 $val);
	if ($type != 2)	// Not common, we can check on POST
		//unset($form);

Fixed code:

		// Clean $filter that may contains sql conditions so sql code
		if (function_exists('test_sql_and_script_inject')) $filter = test_sql_and_script_inject($filter, 3);

 * @param		string		$type		1=GET, 0=POST, 2=PHP_SELF, 3=GET without sql reserved keywords (the less tolerant test)

	if ($type == 3)
		$inj += preg_match('/select|update|delete|replace|group\s+by|concat|count|from/i',	 $val);
	}
	if ($type != 2)	// Not common key strings, so we can check them both on GET and POST
