In OpenJPEG 2.3.0, there is an integer overflow vulnerability in the opj_t1_encode_cblks function (openjp2/t1.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file.

MASTER IPCAMERA01 3.3.4.2103 devices allow remote attackers to obtain sensitive information via a crafted HTTP request, as demonstrated by the username, password, and configuration settings.

MASTER IPCAMERA01 3.3.4.2103 devices allow Unauthenticated Configuration Change, as demonstrated by the port number of the web server.

MASTER IPCAMERA01 3.3.4.2103 devices allow Unauthenticated Configuration Download and Upload, as demonstrated by restore.cgi.

MASTER IPCAMERA01 3.3.4.2103 devices have a hardcoded password of cat1029 for the root account.

Stack-based buffer overflow in the ej_update_variables function in router/httpd/web.c on ASUS routers (when using software from https://github.com/RMerl/asuswrt-merlin) allows web authenticated attackers to execute code via a request that updates a setting. In ej_update_variables, the length of the variable action_script is not checked, as long as it includes a “_wan_if” substring.
