What is CVE-2025-6371?

A vulnerability affecting the D-Link DIR-619L routers allows remote attackers to execute arbitrary code through a stack-based buffer overflow in the 'formSetEnableWizard' function. This issue arises from improper handling of input within the '/goform/formSetEnableWizard' file, specifically via manipulation of the 'curTime' argument. This flaw compromises the security of devices that are no longer supported by D-Link, making them particularly susceptible to exploitation. Users are strongly urged to assess their device's vulnerability status and take action to mitigate potential risks.
