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.

addresses: CWE-798

Enables users to notice when hard-coded credentials have been exploited for unauthorized access.

addresses: CWE-798

Security training explicitly warns against hard-coded credentials, lowering their use in systems.

addresses: CWE-798

Policy and procedures prohibit hard-coded credentials in favor of managed authentication.

addresses: CWE-798

External identity providers eliminate the need for hard-coded credentials in applications.

addresses: CWE-798

Changing default authenticators prior to first use and protecting content prevents use of hard-coded credentials.

addresses: CWE-798

Central credential stores and rotation policies remove the need for hard-coded credentials in configuration files or code.

addresses: CWE-798

Intelligence programs surface reports of campaigns that abuse hard-coded credentials in products, prompting removal or replacement and thereby reducing successful exploitation.

addresses: CWE-798

Planned investment enables secure credential storage and management systems instead of hard-coded credentials.

MITRE ATT&CK Enterprise TechniquesAI

T1078 Valid Accounts Stealth
Adversaries may obtain and abuse credentials of existing accounts as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.
T1552 Unsecured Credentials Credential Access
Adversaries may search compromised systems to find and obtain insecurely stored credentials.
Why these techniques?

Hard-coded credentials directly constitute unsecured credentials (T1552) that enable use of valid accounts (T1078) for authentication.

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description
