Vulnerability Data

A vulnerability in the password change feature of Cisco Firepower Management Center (FMC) software could allow an unauthenticated, remote attacker to determine valid user names on an affected device. This vulnerability is due to improper authentication of password update responses.…

more

An attacker could exploit this vulnerability by forcing a password reset on an affected device. A successful exploit could allow the attacker to determine valid user names in the unauthenticated response to a forced password reset.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-23 directly requires mechanisms to protect against unauthorized data mining and inference from statistical queries that would expose sensitive information.

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-05 mostly match
prevents

Least-privilege query permissions directly limit the data an attacker can request or infer.

DE.CM-03 partial match
prevents

Behavior analytics on query activity can detect inference attempts but does not prevent exposure at query time.

PR.DS-10 partial match
prevents

Protecting data-in-use reduces what remains available for inference via queries.

prevents

Access control limits who can run queries that could expose sensitive information via inference.

prevents

Granular access rights reduce the ability of users to craft inference queries.

prevents

Data masking prevents inference by obscuring sensitive values returned in query results.

prevents

Information access restriction directly limits query scope that could lead to inference.

mitigates

Classification helps identify sensitive data that must be protected from inference attacks.

finds

DLP can detect and block queries or result sets that risk exposing sensitive information.
