Sharp Corporation Vulnerabilities and Affected Products

Generated title:Sharp Network Scanner Tool and Network Scanner Tool Lite Insecure Default Configuration

Network Scanner Tool and Network Scanner Tool Lite provided by Sharp Corporation, with the initial configuration, require no authentication and accept files unlimitedly. When the affected products are used with the initial configuration, anyone can connect to them without authentication and upload files unlimitedly. This may cause a denial-of-service (DoS) condition on the PC. Furthermore, if a malicious file is uploaded, a PC user may be tricked to execute the file to attack other entities from…

Sharp and Toshiba Tec MFPs (multifunction printers) fail to properly authorize requests to directly access certain image data stored to the affected product.

Generated title:Sharp Corporation Routers Missing Authentication for Web APIs

SHARP routers do not perform authentication for some web APIs. The device information may be retrieved without authentication. If the administrative password of the device is left as the initial one, the device may be taken over.

Multiple SHARP routers contain an improper authentication vulnerability in the configuration backup function. The product's backup files containing sensitive information may be retrieved by a remote unauthenticated attacker.

home 5G HR02, Wi-Fi STATION SH-52B, and Wi-Fi STATION SH-54C contain a buffer overflow vulnerability in the hidden debug function. A remote unauthenticated attacker may get the web console of the product down.

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].

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].

Affected devices create coredump files when crashed, storing them with world-readable permission. Any local user of the device can examine the coredump files, and research the memory contents. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

Sharp and Toshiba Tec MFPs improperly validate input data in URI data registration, resulting in a stored cross-site scripting vulnerability. If crafted input is stored by an administrative user, malicious script may be executed on the web browsers of other victim users.
