Improper validation of specified type of input vulnerability in Magarsus Consulting Ltd. Co. IDM-MFA allows Authentication Bypass.
This issue affects IDM-MFA: from 2025.11.27 before 2026.03.10.
AnalysisAI
Authentication bypass in Magarsus Consulting IDM-MFA (versions 2025.11.27 up to but not including 2026.03.10) lets remote unauthenticated attackers circumvent multi-factor authentication by supplying improperly-typed input that the application fails to validate. Because IDM-MFA is itself an identity and MFA gateway, a successful bypass undermines the primary control protecting downstream systems, yielding high confidentiality and integrity impact. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation targets the IDM-MFA authentication/validation routine and hinges on submitting input of an unexpected type that the product fails to type-check (CWE-1287), against affected versions 2025.11.27 through 2026.03.09. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-scored CVSS 3.1 is 8.1 (High) with vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N - network reachable, low complexity, no privileges, but requiring user interaction, with high confidentiality and integrity impact and no availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a request or a link to the IDM-MFA authentication flow containing a specially typed input (for example a parameter sent as an array or object instead of the expected string) that the type-validation logic mishandles, and induces a targeted user to trigger it (satisfying the UI:R requirement). The malformed input causes the MFA verification to be treated as satisfied, granting the attacker an authenticated session to protected resources. … |
| Remediation | Upgrade IDM-MFA to version 2026.03.10 or later, which is the first fixed release per the affected-version range (Vendor-released patch: 2026.03.10). … Detailed patch versions, workarounds, and compensating controls in full report. |
