MediumCVSS 5.7KEVSummary
The D-Link DIR-300 router stores cleartext passwords, which allows context-dependent attackers to obtain sensitive information via unspecified vectors.
Risk Assessment
Anyone with access to the device or its backups can read passwords in plaintext, potentially leading to compromise of the router and the network it protects.
