Deeper analysis
CVE-2024-22751 is a stack-based buffer overflow (CWE-787) present in the sub_477AA0 function of D-Link DIR-882 firmware version DIR882A1_FW130B06. The flaw carries a CVSS 3.1 score of 9.8, reflecting network attack vector, low complexity, and no required authentication or user interaction.
An unauthenticated remote attacker can send a crafted request that triggers the overflow, resulting in arbitrary code execution, information disclosure, or a denial-of-service condition on the affected router. Because the device is typically internet-facing, the vulnerability can be reached directly from the WAN without prior access.
D-Link’s security bulletin page and the accompanying technical write-up on GitHub indicate that firmware updates or configuration changes should be applied; however, the references do not enumerate specific fixed versions or work-arounds beyond the general advisory. The associated EPSS score has remained flat at 0.0564 with no material increase since disclosure.
