Trust: 0.8

sources: JVNDB: JVNDB-2021-018217

DESCRIPTION

An incorrect default permission vulnerability exists in the cgiserver.cgi cgi_check_ability functionality of reolink RLC-410W v3.0.0.136_20121102. In cgi_check_ability the Format API does not have a specific case, the user permission will default to 7. This will give non-administrative users the possibility to format the SD card and reboot the device. Reolink Rlc-410W is a Wifi security camera from China Reolink company. An access control error vulnerability exists in Reolink RLC-410W v3.0.0.136_20121102, which originates from cgiserver.cgi cgi_check_ability not properly restricting resource access from unauthorized roles. An attacker could trigger the vulnerability to cause a denial of service by sending an HTTP request
