Summary

CVE-2025-0893 is a high-severity Improper Privilege Management (CWE-269) vulnerability in Broadcom (inferred from references). Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 24.2th 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 AC-6 (Least Privilege) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploitation for Privilege Escalation (T1068). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly addresses the privilege escalation flaw by requiring identification, reporting, and correction of vulnerabilities like CVE-2025-0893 through patching to SymDiag 3.0.79 or later.

AC-6 Least Privilege good match

prevent

Enforces least privilege to mitigate improper privilege management (CWE-269), limiting the scope and impact of local low-privilege escalation in SymDiag.

AC-3 Access Enforcement partial match

prevent

Requires enforcement of approved access authorizations, helping to block unauthorized privilege escalations attempted via the SymDiag vulnerability.

MITRE ATT&CK Enterprise TechniquesAI

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

Why these techniques?

Local privilege escalation vulnerability due to improper privilege management directly enables T1068 Exploitation for Privilege Escalation, allowing low-privileged local attackers to achieve full system compromise.

NVD Description

Symantec Diagnostic Tool (SymDiag), prior to 3.0.79, may be susceptible to a Privilege Escalation vulnerability.

Deeper analysisAI

CVE-2025-0893 is a Privilege Escalation vulnerability in the Symantec Diagnostic Tool (SymDiag), affecting versions prior to 3.0.79. Published on 2025-02-19, it has a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-269 (Improper Privilege Management).

A local attacker with low privileges (PR:L) can exploit this vulnerability with low attack complexity and no user interaction. Exploitation grants high-impact access to confidentiality, integrity, and availability (C:H/I:H/A:H), enabling full system compromise within the unchanged scope.

Broadcom's security advisory provides mitigation guidance, available at https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/25417. Upgrading to SymDiag 3.0.79 or later addresses the issue in affected versions.
