Vulnerable Systems:
* ESRI version 9.2
Immune Systems:
* ESRI version 9.2 SP2
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.
Analysis:
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.
Workaround:
Employing firewalls to limit access to the affected service can help prevent potential exploitation of this vulnerability.
Vendor response:
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.
