Summary

CVE-2024-45675 is a high-severity Use of Password System for Primary Authentication (CWE-309) vulnerability in Ibm Informix Dynamic Server. Its CVSS base score is 8.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Password Guessing (T1110.001); ranked at the 1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to IA-5 (Authenticator Management) and AC-7 (Unsuccessful Logon Attempts) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

IA-5 Authenticator Management good match

Defines management rules for password authenticators, addressing some shortcomings but still permitting password systems as primary.

AC-7 Unsuccessful Logon Attempts partial match

Limits password guessing attempts, reducing exploitability of password-only primary auth without eliminating the weakness.

IA-2 Identification and Authentication (Organizational Users) partial match

Requires identification and authentication but does not preclude sole reliance on passwords, only partially addressing the weakness.

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-03 mostly match
prevents

Explicitly requires MFA and password-strength policies, directly mitigating password-only primary authentication.

PR.AA-01 partial match
prevents

Credential management practices can reduce sole reliance on weak password systems.

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 full match
degrades

Authentication information control explicitly governs the lifecycle and strength of passwords and alternatives.

A.8.5 Secure authentication full match
degrades

Secure authentication control directly requires and guides non-password or hardened password mechanisms.

A.5.15 Access control partial match
degrades

Access control policy can mandate stronger primary authentication than passwords.

A.5.16 Identity management partial match
degrades

Identity management defines how identities are proven, directly influencing reliance on passwords.

A.5.18 Access rights none match
none

Access rights assignment assumes authentication has already occurred; does not address password weaknesses.

A.8.2 Privileged access rights none match
none

Privileged access rights presuppose secure authentication but do not specify the mechanism.
