Summary

CVE-2024-50618 is a medium-severity Use of Single-factor Authentication (CWE-308) vulnerability in Cipplanner Cipace. Its CVSS base score is 4.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Password Spraying (T1110.003); ranked at the 16th 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-2 (Identification and Authentication (Organizational Users)) and IA-8 (Identification and Authentication (Non-organizational Users)) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

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

ia-2 requires unique identification and authentication of users, directly stopping single-factor schemes by mandating appropriate (multi-factor) mechanisms.

IA-8 Identification and Authentication (Non-organizational Users) good match

ia-8 requires unique identification and authentication of non-organizational users, directly stopping single-factor schemes by mandating appropriate (multi-factor) mechanisms.

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 full match
prevents

Explicit MFA requirement directly eliminates single-factor authentication while the control also addresses broader authentication scope.

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.8.5 Secure authentication full match
degrades

Secure authentication control explicitly requires multi-factor authentication, directly eliminating single-factor weakness.

A.5.17 Authentication information mostly match
degrades

Authentication information control directly addresses the need for strong, multi-factor credentials.

A.5.15 Access control partial match
prevents

Access control policy can mandate multi-factor authentication but does not prescribe the technical implementation.

A.5.18 Access rights partial match
degrades

Access rights provisioning can require MFA, yet the control is broader than authentication strength.

A.8.2 Privileged access rights partial match
degrades

Privileged access rights can be conditioned on MFA, but the control focuses on privilege scope rather than factor count.

A.8.3 Information access restriction partial match
degrades

Information access restriction can enforce MFA, yet the control is wider than authentication mechanisms.
