Summary

CVE-2025-26482 is a medium-severity Exposure of Sensitive System Information Due to Uncleared Debug Information (CWE-1258) vulnerability in Dell Idrac9 Firmware. Its CVSS base score is 4.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked at the 23th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to CM-7 (Least Functionality) and SA-3 (System Development Life Cycle) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

CM-7 Least Functionality partial match

Disabling debug and other non-essential functionality prevents the system from entering a debug state that would expose uncleared sensitive values.

SA-3 System Development Life Cycle partial match

Mandating a security-aware SDLC ensures hardware designs incorporate debug-mode clearing requirements.

SA-4 Acquisition Process partial match

Acquisition requirements can explicitly mandate secure debug behavior and data clearing in supplied hardware.

SA-8 Security and Privacy Engineering Principles partial match

Requiring security engineering principles during design directly addresses the need to clear sensitive data on debug entry.

ID.RA-09 partial match
prevents

Pre-acquisition hardware integrity assessment can identify devices with uncleared debug exposure before purchase.

PR.PS-03 partial match

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development can detect uncleared debug information before release.

A.8.24 Use of cryptography partial match
degrades

Cryptographic key management and secure handling requirements reduce exposure of sensitive values during debug entry.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture and engineering principles directly address clearing of sensitive data on debug transitions.

A.8.28 Secure coding partial match
degrades

Secure coding practices can mandate explicit clearing of debug registers and memory.

A.8.33 Test information partial match
degrades

Test information protection includes ensuring debug artifacts do not leak sensitive data.
