Summary

CVE-2025-50433 is a critical-severity Weak Password Recovery Mechanism for Forgotten Password (CWE-640) vulnerability in Monnit Imonnit. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Valid Accounts (T1078); ranked at the 35th 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-12 (Identity Proofing) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

CVE-2025-50433, published on 2025-11-26, is a critical vulnerability (CVSS 9.8, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) affecting the imonnit.com web application, discovered on 2025-04-24. Classified under CWE-640 (weak password recovery mechanism for forgotten passwords), it enables malicious actors to gain escalated privileges through a crafted password reset process, resulting in the takeover of arbitrary user accounts.

The vulnerability is exploitable by unauthenticated attackers over the network with low attack complexity and no user interaction required. Successful exploitation allows attackers to achieve high-impact compromise of confidentiality, integrity, and availability, specifically by seizing control of any targeted user account on the platform.

Mitigating Controls (NIST 800-53 r5) AI

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 secure distribution, reset, and verification procedures that directly address weak password recovery flows.

Mitigating Controls (NIST CSF 2.0) AI

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 lifecycle management directly includes password reset/recovery flows.

PR.AA-02 mostly match
prevents

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

PR.AA-03 partial match
prevents

Authentication policy covers strength/MFA but does not address recovery path weaknesses.

PR.PS-06 partial match
prevents

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

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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

A.5.17 Authentication information partial match
degrades

Strong authentication-information lifecycle rules directly address weak password-recovery flows.

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
mitigates

Secure-authentication requirements include robust forgotten-password procedures.

A.5.18 Access rights none match
none

Proper access-rights provisioning can limit who can trigger recovery, but does not fix the recovery mechanism itself.
