What it is

⚠️ A crafty crafted packet is all it takes to expose sensitive data! The Moxa Camera VPort 06EC-2V Series is vulnerable due to improper validation of the length field in its LLDP-MED TLV.

An attacker could potentially glean sensitive information from the device, leaving your network open to various threats. While the severity is marked as unknown, the risk of data exposure should never be taken lightly!
