Detailsinfo

A vulnerability classified as problematic was found in Brother/Toshiba Tec/Konica Minolta Printer (version unknown). This vulnerability affects an unknown function. The manipulation with an unknown input leads to a file information disclosure vulnerability. The CWE definition for the vulnerability is CWE-538. The product places sensitive information into files or directories that are accessible to actors who are allowed to have access to the files, but not to the sensitive information. As an impact it is known to affect confidentiality. CVE summarizes:

By using the "uscan" protocol provided by the eSCL specification, an attacker can discover the serial number of multi-function printers that implement the Brother-provided firmware. This serial number can, in turn, can be leveraged by the flaw described by CVE-2024-51978 to calculate the default administrator password. This flaw is similar to CVE-2024-51977, with the only difference being the protocol by which an attacker can use to learn the remote device's serial number. The eSCL/uscan vector is typically only exposed on the local network.

The weakness was shared by Rob King. The advisory is shared for download at support.brother.com. This vulnerability was named CVE-2025-8452 since 08/01/2025. The exploitation appears to be easy. The attack needs to approached within the local network. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 08/15/2025). The MITRE ATT&CK project declares the attack technique as T1083.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
