Description

Abdul-Aziz Hariri has discovered a vulnerability in MaxDB, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to a NULL-pointer dereference error in the SAP DBTech-MAXDB service (kernel.exe) when processing certain login handshake packets. This can be exploited to crash the service via specially crafted packets sent to e.g. TCP port 7200 or 7210.

The vulnerability is confirmed in version 7.8.01.18. Other versions may also be affected.
