TITLE

Moxa Camera VPort 06EC-2V has unspecified vulnerabilities

Trust: 0.6

sources: CNVD: CNVD-2021-36217

DESCRIPTION

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. Moxa Camera VPort 06EC-2V is a camera equipment of Taiwan Moxa (MOXA) Company. Moxa Camera VPort 06EC-2V has security vulnerabilities. The attacker can control the loop counter variable through the elaborate lldp data packet to obtain the leaked information
