CVE-2021-25848
First published: Mon May 10 2021(Updated: )
Improper validation of the length field of LLDP-MED TLV in userdisk/vport_lldpd in Moxa Camera VPort 06EC-2V Series, version 1.1, allows information disclosure to attackers due to using fixed loop counter variable without checking the actual available length via a crafted lldp packet.
