MySQL 5.0.x – IF Query Handling Remote Denial of Service
source: https://www.securityfocus.com/bid/23911/info MySQL is prone to a remote denial-of-service vulnerability because it fails to handle certain specially crafted queries. An attacker can exploit this issue to crash the application, denying access to legitimate users. NOTE: An attacker must be able to execute arbitrary SELECT statements against the database to exploit this issue. This may be through legitimate means or by exploiting other latent SQL-injection vulnerabilities. Versions prior to MySQL 5.0.40 are vulnerable. SELECT id from example WHERE id IN(1, (SELECT IF(1=0,1,2/0))); |
