TITLE

DASAN H660RM Vulnerabilities related to the use of hard-coded credentials in device firmware

Trust: 0.8

sources: JVNDB: JVNDB-2019-003423

DESCRIPTION

DASAN H660RM devices with firmware 1.03-0022 use a hard-coded key for logs encryption. Data stored using this key can be decrypted by anyone able to access this key. DASAN H660RM is a GPON optical network terminal equipment produced by Korea DASAN Company. A trust management issue vulnerability exists in DASAN H660RM with firmware version 1.03-0022. This vulnerability stems from the lack of an effective trust management mechanism in network systems or products. Attackers can use default passwords or hard-coded passwords, hard-coded certificates, etc. to attack affected components
