Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-14 Permitted Actions Without Identification or Authentication good match

prevent

AC-14 requires organizations to explicitly limit and document permitted actions without authentication, directly preventing unauthenticated access to sensitive API secrets via management endpoints.

AC-3 Access Enforcement good match

prevent

AC-3 enforces approved authorizations for access to system resources, mitigating the vulnerability by ensuring the API endpoint requires authentication before disclosing secrets.

IA-5 Authenticator Management good match

prevent

IA-5 mandates protection of authenticators like API secrets from unauthorized disclosure, addressing the exposure of credentials that enable privileged operations.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

Vulnerability in public API endpoint enables unauthenticated credential disclosure (T1552) and direct exploitation of exposed public-facing application (T1190) to obtain valid API secrets for privileged access.

leading to unauthorized access.

Deeper analysisAI

CVE-2026-23782 is a vulnerability discovered in BMC Control-M/MFT versions 9.0.20 through 9.0.22. The issue resides in an API management endpoint that permits unauthenticated users to retrieve both an API identifier and its corresponding secret value, exposing sensitive credentials that should remain protected.

Unauthenticated remote attackers can exploit this vulnerability with low complexity, requiring no privileges or user interaction, as indicated by its CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). By obtaining the exposed API secrets, attackers can invoke privileged API operations, potentially resulting in unauthorized access to the system.
