SERVER-WEBAPP -- Snort has detected traffic exploiting vulnerabilities in web based applications on servers.
SERVER-WEBAPP Dahua DVR firmware version query attempt
This event is generated when a Dahua DVR, or potentially another DVR leveraging the same binary protocol, is being sent a request to query the firmware version of the camera. At this time, requests sent over this protocol are unauthenticated. Impact: Attempted Information Leak Details: An attacker sends a command to the vulnerable DVR and since the request is unauthenticated, the DVR executes the request. In this case the request is to query the firmware version. The rule looks for the following: 0xA4000000 -> Command dword 0x00000000 -> Null dword 0x08000000 -> Specifier for command (denotes firmware) Two dwords of nulls: 0x00000000 0x00000000 Ease of Attack: Simple and publicly available.
