CVE-2025-21111
Published: 08 January 2025
Summary
CVE-2025-21111 is a high-severity Plaintext Storage of a Password (CWE-256) vulnerability in Dell Vxrail D560 Firmware. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Credentials In Files (T1552.001); ranked at the 17.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 IA-5 (Authenticator Management) and SC-28 (Protection of Information at Rest).
Deeper analysis
CVE-2025-21111 is a Plaintext Storage of a Password vulnerability affecting Dell VxRail systems in versions 8.0.000 through 8.0.311. This flaw, mapped to CWE-256 (Plaintext Storage of a Password) and CWE-522 (Insufficiently Protected Credentials), involves the insecure storage of sensitive credentials in plaintext within the affected component.
A high-privileged attacker with local access could potentially exploit this vulnerability, as indicated by its CVSS v3.1 base score of 7.5 (AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H). Successful exploitation would lead to information exposure, with high impacts on confidentiality, integrity, and availability in a scoped attack scenario.
