Deeper analysis
CVE-2023-45572 is a buffer overflow vulnerability, tracked under CWE-787, that affects multiple D-Link router models including DI-7003GV2.D1 up to version 23.08.25D1, DI-7100G+V2.D1 and DI-7100GV2.D1 up to 23.08.23D1, DI-7200G+V2.D1 and DI-7200GV2.E1 up to 23.08.23E1 or 23.08.23D1, and DI-7300G+V2.D1 plus DI-7400G+V2.D1 up to 23.08.23D1. The flaw resides in the tgfile.htm endpoint and is triggered through the fn parameter, enabling out-of-bounds writes during processing.
An unauthenticated remote attacker can supply a crafted fn value over the network to trigger the overflow and achieve arbitrary code execution on the device. The vulnerability carries a CVSS 3.1 score of 9.8, reflecting that no authentication, user interaction, or special network conditions are required for successful exploitation.
Public references consist of GitHub reports detailing the issue, but no vendor advisories, firmware patches, or official mitigation guidance are referenced in the available sources. The associated EPSS scores have remained low, with a current value of 0.0723 and a peak of 0.0815.
