Out-of-bounds read vulnerability exists in Sharp Corporation and Toshiba Tec Corporation multiple MFPs (multifunction printers), which may lead to a denial-of-service (DoS) condition.

The web interface of the affected devices process some crafted HTTP requests improperly, leading to a device crash. More precisely, a crafted parameter to billcodedef_sub_sel.html is not processed properly and device-crash happens. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

Cross-site scripting vulnerability exists in Sharp Corporation and Toshiba Tech Corporation multiple MFPs (multifunction printers). If this vulnerability is exploited, an arbitrary script may be executed on the administrative page of the affected MFPs. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

API keys for some cloud services are hardcoded in the "main" binary. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

There are several hidden accounts. Some of them are intended for maintenance engineers, and with the knowledge of their passwords (e.g., by examining the coredump), these accounts can be used to re-configure the device. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

The web interface of the affected devices is designed to hide the LDAP credentials even for administrative users. But configuring LDAP authentication to "SIMPLE", the device communicates with the LDAP server in clear-text. The LDAP password can be retrieved from this clear-text communication. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

Admin authentication can be bypassed with some specific invalid credentials, which allows logging in with an administrative privilege. Sharp Corporation states the telnet feature is implemented on older models only, and is planning to provide the firmware update to remove the feature. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

"sessionlist.html" and "sys_trayentryreboot.html" are accessible with no authentication. "sessionlist.html" provides logged-in users' session information including session cookies, and "sys_trayentryreboot.html" allows to reboot the device. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

Improper processing of some parameters of installed_emanual_list.html leads to a path traversal vulnerability. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

User passwords are decrypted and stored on memory before any user logged in. Those decrypted passwords can be retrieved from the coredump file. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].
