Summary

CVE-2025-6097 is a medium-severity Unverified Password Change (CWE-620) vulnerability in Utt 750W Firmware. Its CVSS base score is 5.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Account Manipulation (T1098); ranked at the 45th percentile by exploit likelihood (below the median); 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.

CVE-2025-6097 affects the UTT 进取 750W router up to version 5.0. The flaw resides in the formDefineManagement function within the /goform/setSysAdm endpoint of the Administrator Password Handler component. An unauthenticated remote attacker can supply a manipulated passwd1 argument to perform an unverified password change, which maps to CWE-620 and CWE-640.

Because the vulnerability can be triggered over the network without credentials or user interaction, an attacker who reaches the management interface can alter the administrator password and thereby obtain persistent administrative control of the device. Public proof-of-concept code demonstrating the attack has been released.

The vendor was notified prior to disclosure but has not issued a response or patch. The associated EPSS score has remained flat at 0.0104 with no material increase since publication, indicating limited observed exploitation interest to date.

Mitigating Controls (NIST 800-53 r5) AI

IA-11 Re-authentication good match

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

IA-12 Identity Proofing good match

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

IA-5 Authenticator Management good match

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

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-01 mostly match
prevents

Credential management practices directly enforce re-authentication for password changes.

PR.AA-02 mostly match
prevents

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

PR.AA-03 mostly match
prevents

Authentication requirements include verifying identity before allowing credential modifications.

PR.PS-06 partial match

Secure SDLC reduces implementation flaws but is not specific to password-recovery design.

A.5.17 Authentication information partial match
degrades

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

A.8.25 Secure development life cycle partial match
prevents

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

A.8.26 Application security requirements partial match
prevents

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

A.8.28 Secure coding partial match
prevents

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

A.8.5 Secure authentication partial match
prevents

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

A.5.16 Identity management none match
none

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