Description: Makunet maku-boot 4.3.0 through 5.0.0 contains a missing authorization vulnerability that allows authenticated users to read mail and SMS configurations by calling /sys/mail/config/list and /sys/sms/config/list without the required authority checks. Attackers can retrieve unmasked SMTP passwords and Aliyun, Tencent Cloud, Qiniu or Huawei Cloud access keys, and abuse /sys/mail/config/send to send mail to arbitrary recipients.
