Environmental Systems Research Institute (ESRI) ArcSDE is a multi-user database server that has been bundled with ArcGIS to provide access to Geographic Information Systems (GIS). More information is available at ESRI's web site located at the following URL.
Remote exploitation of a buffer overflow vulnerability within Environmental Systems Research Institute (ESRI) Inc.'s ArcSDE service allows attackers to execute arbitrary code in the context of the running service.
This vulnerability appears to exist in the handling of requests containing overly long string parameters. By supplying a specially crafted request, the ArcSDE server will overflow a buffer and overwrite execution control information stored on the stack.
Exploitation allows attackers to execute arbitrary code with the privileges of the running service.
No authentication is required to exploit this vulnerability. The attacker only needs the ability to converse with the server via the TCP port on which it is listening. By default the server listens on port 5151.
An iDefense contributor reported that version 9.2 is vulnerability to this attack. ESRI confirmed the vulnerability. All prior versions are suspected to be vulnerable.
Employing firewalls to limit access to the affected service can help prevent potential exploitation of this vulnerability.
ESRI has identified this issue as NIM007075 and corrected the vulnerability by releasing ArcGIS 9.2 Service Pack 2. Additionally, ESRI released the "Three Tiered Connection Security Patch" to address the problem in older versions. For more information see ESRI's notifications at the following URLs.
