MITRE ATT&CK Enterprise TechniquesAI

T1040 Network Sniffing Credential Access
Adversaries may passively sniff network traffic to capture information about an environment, including authentication material passed over the network.
attack.mitre.org →
T1557 Adversary-in-the-Middle Credential Access
Adversaries may attempt to position themselves between two or more networked devices using an adversary-in-the-middle (AiTM) technique to support follow-on behaviors such as [Network Sniffing](https://attack.
attack.mitre.org →
Why these techniques?

Cleartext credential exposure in HTTP responses directly enables network sniffing (T1040) and adversary-in-the-middle interception (T1557) by on-path attackers.

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.

AT-3 Role-based Training
addresses: CWE-319

Role-based training covers secure transmission methods, mitigating cleartext transmission of sensitive data.

CA-3 Information Exchange
addresses: CWE-319

By requiring documented security controls for information exchanges, the control reduces the risk of cleartext transmission of sensitive data.

CM-13 Data Action Mapping
addresses: CWE-319

Mapping transmission actions in data flows helps prevent cleartext transmission of sensitive information.

CM-6 Configuration Settings
addresses: CWE-319

Settings can enforce secure transmission protocols to prevent cleartext transmission of sensitive data.

MP-1 Policy and Procedures
addresses: CWE-319

Policy addresses secure transport and handling of media to avoid cleartext transmission of sensitive information.

PM-17 Protecting Controlled Unclassified Information on External Systems
addresses: CWE-319

Enforces safeguards against cleartext transmission of CUI when data leaves organizational boundaries to external systems.

SA-9 External System Services
addresses: CWE-319

Explicit controls and continuous oversight on external system services prevent cleartext transmission of sensitive information over provider-managed channels.

SC-12 Cryptographic Key Establishment and Management
addresses: CWE-319

Key-establishment procedures specify secure distribution channels that preclude cleartext transmission of key material.
