CVE-2025-25745
Published: 14 February 2025
Description
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Security Summary
CVE-2025-25745 is a stack-based buffer overflow vulnerability (CWE-121) affecting the D-Link DIR-853 router running firmware version A1 FW1.20B07. The flaw resides in the SetQuickVPNSettings module, where insufficient bounds checking on the Password parameter allows an overflow condition during processing of user-supplied input. Published on 2025-02-14, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact.
A remote, unauthenticated attacker can exploit this vulnerability over the network with low complexity by tricking a user into interacting with a malicious input, such as submitting a specially crafted Password value through the affected module. Successful exploitation could result in high-impact consequences, including arbitrary code execution, data compromise, modification of system integrity, or denial of service, granting the attacker substantial control over the targeted device.
