Summary

CVE-2020-37172 is a high-severity Weak Password Recovery Mechanism for Forgotten Password (CWE-640) vulnerability in Wwbn Avideo. Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Valid Accounts (T1078); ranked at the 50th 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.

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

CVE-2020-37172 is a cross-site request forgery (CSRF) vulnerability in AVideo Platform version 8.1. The flaw resides in the password recovery mechanism, particularly the recoverPass endpoint, which attackers can exploit by crafting malicious requests that leverage a user's recovery token to reset passwords without requiring authentication.

Unauthenticated attackers with network access can exploit this vulnerability, which has a CVSS score of 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N) and is associated with CWE-640. Exploitation allows them to change user account credentials, potentially granting unauthorized access to affected accounts.

Advisories and additional details are documented in resources such as the Vulncheck advisory at https://www.vulncheck.com/advisories/avideo-platform-cross-site-request-forgery-password-reset, an Exploit-DB entry at https://www.exploit-db.com/exploits/48003, and official AVideo sites including https://avideo.com and https://github.com/WWBN/AVideo; practitioners should review these for mitigation guidance and patches.

A proof-of-concept exploit is available on Exploit-DB, highlighting the risk of real-world exploitation.

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.
