MaxDB by MySQL is a re-branded and enhanced version of SAP DB, SAP AG's open source database. MaxDB is a heavy-duty, SAP-certified open source database that offers high availability, scalability and a comprehensive feature set. MaxDB complements the MySQL database server, targeted for large mySAP ERP environments and other applications that require maximum enterprise-level database functionality.
Remote exploitation of an input validation error in MySQL MaxDB could allow attackers to trigger a denial of service condition.
The problem exists due to improper input validation of a user-supplied variable in the IsAscii7() function. Remote attackers can send a specially crafted HTTP request to webdbm with the 'Server' value containing ASCII values above 0x7F to cause an assert directive to fail, resulting in a DoS condition.
