Official Description
Buffer Overflow vulnerability in D-Link device DI-7003GV2.D1 v.23.08.25D1 and before, DI-7100G+V2.D1 v.23.08.23D1 and before, DI-7100GV2.D1 v.23.08.23D1, DI-7200G+V2.D1 v.23.08.23D1 and before, DI-7200GV2.E1 v.23.08.23E1 and before, DI-7300G+V2.D1 v.23.08.23D1, and DI-7400G+V2.D1 v.23.08.23D1 and before allows a remote attacker to execute arbitrary code via the fn parameter of the file.data function.
Risk Analysis
This buffer overflow in the file.data function of D-Link devices allows remote attackers to execute arbitrary code. The critical 9.8 CVSS score reflects the ease of exploitation and potential impact.
No public exploit exists, and it is not tracked in the CISA KEV. The vulnerability is remotely exploitable.
Update the device firmware to the latest version released by D-Link.
Technical Analysis
CVE-2023-45574 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
