This indicates a possible attempt to exploit a buffer overflow vulnerability in Computer Associates BrightStor products and iGateway.
The iGateway component fails to properly handle specially crafted HTTP GET requests. By sending specially crafted HTTP GET requests to port 5250 when the debug mode is enabled (which is not the system default), a remote or local attacker could overflow a buffer and execute arbitrary code on the target system.
