Fortinet Discovers Cisco FindIT DLL Preloading Vulnerability
Fortinet's FortiGuard Labs has discovered a DLL preloading vulnerability in Cisco FindIT.
Cisco FindIT is a simple network discovery utility which helps you to monitor and manage your local network from a convenient toolbar in your web browser. Cisco FindIT automatically discovers all supported Cisco Small Business devices in the same local network segment as your PC.
Cisco FindIT is susceptible to a DLL preloading vulnerability. The issue occurs when the application looks to load a DLL for execution and an attacker provides a malicious DLL to use instead. The application generally follows a specific search path to locate the DLL. The vulnerability can be exploited by a simple file write (or potentially an over-write) which results in a foreign DLL running under the context of the application.
Users should apply the solution provided by Cisco.
Fortinet reported the vulnerability to Cisco on June 15, 2017.
Cisco released patch for it on September 20, 2017.
