Vulnerability details

An improper check for an exceptional condition in the Insider Threat Management (ITM) Server could be used by an attacker to change the server's configuration of any already-registered agent so that the agent sends all future communications to an attacker-chosen…

URL. This could result in disclosure of sensitive data events from the agent about the personally identifiable information (PII) and intellectual property it monitors, and all such data could be altered or deleted before reaching the ITM Server. An attacker must first successfully obtain valid agent credentials and agent hostname. All versions prior to 7.14.3.69 are affected.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-754

Requires detection and response to audit logging failures as an unusual or exceptional condition.

addresses: CWE-754

Implements detection of unusual or exceptional conditions followed by safe mode entry, reducing the window for exploitation of unchecked conditions.

addresses: CWE-754

Training ensures users perform required checks for unusual or exceptional conditions as part of contingency roles, limiting attacker leverage from skipped validations.

addresses: CWE-754

IR testing directly validates checks for unusual or exceptional conditions that could indicate security incidents.

addresses: CWE-754

Requires ongoing monitoring of organization-defined metrics and analysis, enabling checks for unusual or exceptional conditions.

addresses: CWE-754

Security testing routinely checks for unusual or exceptional inputs/conditions, identifying missing validation steps that flaw remediation then resolves.

addresses: CWE-754

Requires detection of unusual conditions followed by a controlled transition to the defined failure state.

addresses: CWE-754

MTTF determination forces explicit checks for conditions that precede predictable component failure.
