Summary

CVE-2024-34519 is a medium-severity Authentication Bypass by Alternate Name (CWE-289) vulnerability in Avantra Server (inferred from references). Its CVSS base score is 6.8 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 31th 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-4 (Identifier Management) — 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

Requiring unique identification and authentication of users forces the system to resolve all name variants to a single identity before access is granted.

IA-4 Identifier Management good match

Identifier management directly requires authorization and uniqueness checks that eliminate alternate-name aliases for the same actor or resource.

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

Strong authentication mechanisms directly prevent name-based bypass when they enforce canonical name checks.

PR.AA-01 partial match
prevents

Proper identity management reduces alternate-name collisions but does not guarantee canonicalization inside the auth decision.

PR.AA-05 partial match
prevents

Authorization policy enforcement assumes correct identity; the weakness occurs before policy is applied.

A.5.15 Access control partial match
prevents

Access-control policy can mandate canonical-name checks but does not prescribe the technical implementation.

A.5.16 Identity management partial match
prevents

Identity-management processes can require unique, canonical identifiers, reducing alternate-name bypass risk.

A.5.17 Authentication information partial match
degrades

Proper management of authentication credentials can include rules against duplicate or alias identities.

A.5.18 Access rights partial match
prevents

Access-rights provisioning can enforce canonical-name validation when granting rights.

A.8.3 Information access restriction partial match
prevents

Information-access-restriction mechanisms can implement canonical-name checks to prevent bypass.

A.8.5 Secure authentication partial match
prevents

Secure-authentication controls can require canonical identifiers and reject alternate names.
