Description
CERT Polska has received a report about vulnerabilities in Hongdian 4G Cellular Router (H8951-4G-ESP) firmware and participated in coordination of their disclosure.
The vulnerability CVE-2023-49253 is a predefined root password. Root user password is hardcoded into the device and cannot be changed in the user interface.
The vulnerability CVE-2023-49254 allows authenticated user to execute arbitrary commands in the context of the root user by providing payload in the "destination" field of the network test tools. This is similar to the vulnerability CVE-2021-28151 mitigated on the user interface level by blacklisting characters with JavaScript, however, it can still be exploited by sending POST requests directly.
The vulnerability CVE-2023-49255 allows access router console without authentication. The router console is accessible without authentication at "data" field, and while a user needs to be logged in order to modify the configuration, the session state is shared. If any other user is currently logged in, the anonymous user can execute commands in the context of the authenticated one.
The vulnerability CVE-2023-49256 allows to download the configuration backup without authorization and decrypt included passwords using hardcoded static key.
The vulnerability CVE-2023-49257 allows authenticated user to upload an arbitrary CGI-compatible file using the certificate upload utility and execute it with the root user privileges.
The vulnerability CVE-2023-49258 is cross-site scripting (XSS) located at "/gui/terminal_tool.cgi" in the "data" parameter.
The vulnerability CVE-2023-49259 allows to brute-force the authentication cookies, which are generated using a weak algorithm based on the username, hardcoded secret and the up-time.
The vulnerability CVE-2023-49260 allows to change the MOTD banner and perform an XSS attack.
The vulnerability CVE-2023-49261 allows to take "tokenKey" value from HTML source code of the login page.
The vulnerability CVE-2023-49262 allows to bypass the authentication mechanism by overflowing the value of the Cookie "authentication" field, provided there is an active user session.
The manufacturer, Hongdian Company, has removed vulnerabilities in version (build) 2310271149, which was confirmed by the reporter.
