Summary

CVE-2025-4903 is a medium-severity Unverified Password Change (CWE-620) vulnerability in Dlink Di-7003G Firmware. Its CVSS base score is 6.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Account Manipulation (T1098); ranked in the top 48% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to IA-11 (Re-authentication) and IA-12 (Identity Proofing) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A critical vulnerability tracked as CVE-2025-4903 exists in the D-Link DI-7003GV2 router on firmware version 24.04.18D1 R(68125). The issue occurs in function sub_41F4F0 of /H5/webgl.asp when handling parameters such as tggl_port, remote_management, http_passwd, and exec_service; improper handling permits an unverified password change and is tracked under CWE-620 and CWE-640.

An unauthenticated attacker can exploit the flaw over the network by submitting a crafted request to the web interface, resulting in an immediate administrative password reset that grants control of the device. The exploit has already been published publicly.

EPSS remains flat at 0.0169 with no material rise after disclosure. Public references include a detailed technical write-up on GitHub, multiple VulDB entries, and the vendor site, though no specific mitigation steps or firmware patches are described in the available information.

Mitigating Controls (NIST 800-53 r5) AI

Re-authentication explicitly requires users to prove identity before performing sensitive actions such as password changes.

Identity proofing at appropriate assurance levels ensures forgotten-password recovery cannot succeed without strong verification of the user.

Authenticator management requires identity verification during password distribution and changes, directly stopping unverified password updates.

Identity proofing is the core control that prevents weak or bypassed recovery mechanisms.

degrades

Requires secure management of authentication information, directly addressing the need to verify the original password before allowing a change.

prevents

Secure-SDLC practices can embed strong recovery design, yet the control is broader than this single weakness.

prevents

Application-security requirements can mandate secure recovery flows, but the control covers many other requirements.

prevents

Secure-coding standards can prevent weak recovery implementations, yet the control is wider in scope.

prevents

Mandates secure authentication mechanisms, which include verifying existing credentials before permitting password changes.

none

Identity management processes can incorporate verification steps, but the control itself does not explicitly require password-change verification.
