Summary

CVE-2026-1325 is a medium-severity Weak Password Recovery Mechanism for Forgotten Password (CWE-640) vulnerability in Sangfor Operation And Maintenance Security Management System. Its CVSS base score is 5.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Valid Accounts (T1078); ranked at the 42th 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-2026-1325 is a security vulnerability affecting the Sangfor Operation and Maintenance Security Management System in versions up to 3.0.12. The flaw resides in the edit_pwd_mall function within the /fort/login/edit_pwd_mall file, where manipulation of the "flag" argument enables weak password recovery. It carries a CVSS v3.1 base score of 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N) and is linked to CWE-640.

Unauthenticated remote attackers can exploit this vulnerability with low attack complexity and no user interaction required. Exploitation involves manipulating the specified argument to trigger weak password recovery, resulting in low integrity impact but no confidentiality or availability disruption.

Advisories from VulDB and a related GitHub issue detail the vulnerability, noting that a public exploit has been released and may be used in attacks. The vendor was contacted early for disclosure but provided no response, and no patches or official mitigations are available.

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.
