The user input of a given query is being sanitized (PHP, real_escape_string), yet the query fails with "Illegal mix of collations". This query is below:
SELECT * FROM `table` WHERE `column` = "�½��ļ���.zip"
Does this imply that this query is vulnerable to SQL Injection? If not, is there any disclosure or other vulnerability that this input may provide the attacker?
Edit: This particular request appears to have come from Acunetix Vulnerability Scanner. If this is accurate, there must be some value to an attacker in providing this value in a request. What results might the scanner have been expecting?
