Denial of service via network

Description:
Defcom Labs released an advisory (def-2001-15) describing a denial of service vulnerability in the O'Reilly WebSite Pro's remote manager service.
The remote manager service, which runs by default on port 9999, will reportedly leak memory if non-authenticated requests are repeatedly made to the /dyn/ directory and will eventually crash.
An example request:
GET /dyn/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx HTTP/1.0
host: 10.0.0.1
The vendor has been contacted.
Note that on March 6, 2001, Tim O'Reilly announced that O'Reilly software will not continue with further development of its products, but that its products will continue to be supported and sold.
|
Impact:
A remote user with access to the server's remote service port could cause the server to crash.
|
Solution:
No solution was available at the time of this entry. The author of the advisory recommends that users disallow access to the remote manager service from untrusted networks (the service runs on TCP port 9999 by default).
