HTTP: Cisco WebEx Player .WRF Stack Buffer Overflow
This signature detects attempts to exploit a known stack buffer overflow vulnerability in Cisco WebEx Player. It's due to improper handling of specially crafted .wrf files which results in a stack buffer overflow that can overwrite a function pointer to create reliable code execution. A successful attack can result in arbitrary code execution in the context of the application.
Extended Description
Cisco WebEx is prone to multiple remote buffer-overflow vulnerabilities because it fails to perform adequate boundary-checks on user-supplied data. An attacker can exploit these issues to execute arbitrary code with the privileges of the affected application. Failed exploit attempts will result in a denial-of-service condition.
