CVE-2024-58388 is a high-severity path traversal vulnerability affecting multiple Sharp Corporation multifunction printers. It allows unauthenticated remote attackers to read arbitrary files on the device by manipulating the 'path' parameter in the installed_emanual_down.html endpoint. This can lead to exposure of sensitive system files such as /etc/passwd and credential-containing coredump files. The vulnerability was publicly observed in exploitation attempts as of July 30, 2024.

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 that PC.

Sharp and Toshiba Tec MFPs (multifunction printers) for a certain market have been shipped with the user authentication feature disabled in the initial configuration. When used with the initial configuration, the address book editing and a range of features related to Document Filing can be accessed without user authentication. Products intended for the Japanese market are not affected.

Sharp and Toshiba Tec MFPs (multifunction printers) caches data internally when printing, and leave them uncleared. They may be accessed later by other users.

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

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.

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].

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].

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].

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].

The web interface of the affected devices processes a cookie value improperly, leading to a stack buffer overflow. More precisely, giving too long character string to MFPSESSIONID parameter results in a stack buffer overflow. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].
