Name of the Vulnerable Software and Affected Versions BUFFALO VR-S1000 versions 2.37 and earlier

Description The issue is related to the use of a hard-coded cryptographic key in the firmware, which may allow an attacker to analyze the password of a specific product user. This could potentially lead to unauthorized access. The vulnerability is associated with the use of pre-installed credentials.

Recommendations For versions 2.37 and earlier, consider updating the firmware to a version that does not use a hard-coded cryptographic key, if available. As a temporary workaround, restrict access to the device to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
