Likely Mitigating ControlsAI
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.
Role-based training covers secure transmission methods, mitigating cleartext transmission of sensitive data.
By requiring documented security controls for information exchanges, the control reduces the risk of cleartext transmission of sensitive data.
Mapping transmission actions in data flows helps prevent cleartext transmission of sensitive information.
Settings can enforce secure transmission protocols to prevent cleartext transmission of sensitive data.
Policy addresses secure transport and handling of media to avoid cleartext transmission of sensitive information.
Enforces safeguards against cleartext transmission of CUI when data leaves organizational boundaries to external systems.
Explicit controls and continuous oversight on external system services prevent cleartext transmission of sensitive information over provider-managed channels.
Key-establishment procedures specify secure distribution channels that preclude cleartext transmission of key material.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Cleartext transmission (CWE-319) directly enables passive network sniffing to capture exposed sensitive data over remote network access.
NVD Description
Dell ECS, versions 3.8.1.0 through 3.8.1.7, and Dell ObjectScale versions prior to 4.2.0.0, contains a Cleartext Transmission of Sensitive Information vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to information exposure.
Deeper analysisAI
CVE-2026-22271 is a Cleartext Transmission of Sensitive Information vulnerability (CWE-319) present in Dell ECS versions 3.8.1.0 through 3.8.1.7 and Dell ObjectScale versions prior to 4.2.0.0. Published on 2026-01-23, the issue has a CVSS v3.1 base score of 7.5 (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high potential impact despite elevated complexity and user interaction requirements.
An unauthenticated attacker with remote network access could potentially exploit this vulnerability, leading to information exposure. Exploitation requires high attack complexity and user interaction, such as tricking a user into performing an action, but successful attacks could result in high confidentiality, integrity, and availability impacts within the unchanged scope.
