Summary

FRAgent.exe in Mandiant First Response (MFR) before 1.1.1, when run in daemon mode and when the agent is bound to 0.0.0.0 (all interfaces), opens sockets in non-exclusive mode, which allows local users to hijack the socket, and capture data or cause a denial of service (loss of daemon operation). Successful exploitation requires that the affected products are run in daemon mode and when the agent is bound to 0.0.0.0 (all interfaces). This vulnerability is addressed in the following product release: Mandiant, First Response, 1.1.1

descriptionThe remote host contains a version of First Response, an incident response tool, that is affected by multiple vulnerabilities. If the First Response agent (fragent) is configured to listen for remote SSL-enabled connections, it is reportedly possible to disable the agent remotely by sending a series of specially crafted requests, thereby preventing legitimate connections from a First Response Command Console. Additionally, it is possible to hijack the agent by binding to the same socket address on which it is already listening if it was bound to the
