NIP6800;Secospace USG6600;USG9500 products with versions of V500R001C30; V500R001C60SPC500; V500R005C00SPC100 have an out-of-bounds read vulnerability. An unauthenticated attacker crafts malformed message with specific parameter and sends the message to the affected products. Due to insufficient validation of message, which may be exploited to cause the device reboot.
