FGA-2008-23:EMC NetWorker Denial of Service Vulnerability
Fortinet's FortiGuard Global Security Research Team Discovers Vulnerability in EMC NetWorker
A resource exhaustion vulnerability exists throughout multiple EMC products through an exploited RPC interface.
Denial of service.
NetWorker Server, Storage Node and Client 7.4 SP3
NetWorker Server, Storage Node and Client 7.3 SP4 build 565
NetWorker Client and Storage Node for Open VMS 7.3.2 ECO7
NetWorker Module for Microsoft Exchange 5.1 SP1
NetWorker Module for Microsoft Applications 2.1
NetWorker Module for Meditech 2.0 SP1
NetWorker PowerSnap 2.4 SP2
The RPC interface used by the affected EMC products does not properly enforce bounds checking on a parameter which is used to allocate memory on the heap. The vulnerable NetWorker products use the process "nsrexecd.exe". A remote attacker can exploit this by repeatedly sending requests to the RPC interface, each time allocating more and more memory. Eventually system resources will be exhausted, and denial of service is achieved.
