Title: 4D WebServer Long HTTP Request Buffer Overflow Vulnerability
Severity: HIGH
Description:
4D WebServer is a client/server database management system with integrated web development and serving. It runs on Microsoft Windows and MacOS operating systems.
Due to insufficient bounds checking of HTTP requests, 4D WebServer is prone to a buffer overflow condition. It is possible to overwrite stack variables such as the return address by overflowing either of these fields. This may enable a remote attacker to cause a denial of service or execute attacker-supplied instructions.
It should be noted that the software will run in the SYSTEM context on multi-user Windows operating systems, so successful exploitation may result in a full compromise of the host.
This issue may be similar to the vulnerability discussed in BID 4665, 4D WebServer Authentication Buffer Overflow.
This issue was reported for 4D WebServer version 6.7.3, earlier versions may also be affected.
Affected Products:
- 4D WebServer 6.7.3
