CVE-2021-44207 is a high-severity Use of Hard-coded Credentials (CWE-798) vulnerability in Acclaimsystems Usaherds. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked in the top 3% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Acclaim USAHERDS versions through 7.4.0.1 contain hard-coded credentials, classified under CWE-798. This affects the USAHERDS application developed by Acclaim Systems and carries a CVSS 3.1 base score of 8.1, reflecting network attack vectors with high impact on confidentiality, integrity, and availability despite elevated attack complexity.

An unauthenticated remote attacker can leverage the embedded credentials to authenticate to the application and obtain full administrative control, enabling arbitrary data access, modification, or disruption of herd management operations without user interaction.

Mandiant's disclosure (MNDT-2021-0012) and the vendor site provide technical details on the issue, while CISA lists the vulnerability in its Known Exploited Vulnerabilities catalog, confirming observed in-the-wild exploitation and underscoring the need for affected organizations to apply available updates or configuration changes promptly.

Mitigating Controls

Likely Mitigating Controls AI

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.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-01 partial match
prevents

PR.AA-01's credential/key-management processes can reduce the incentive to embed secrets but do not address or detect hard-coded values in source code, so the weakness remains fully possible.

PR.AA-02 none match
prevents

PR.AA-02 addresses human identity proofing and per-person credential issuance at enrollment; it has no bearing on whether developers embed static credentials in software.

PR.DS-01 none match
prevents

PR.DS-01 addresses encryption and integrity of stored data but never touches credential or key management practices, so it neither prevents hard-coded credentials nor removes any of their risk.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Education on secure configuration practices discourages technical staff from embedding or relying on hard-coded credentials in systems and applications.

mitigates

Secure key-generation, distribution and storage procedures reduce the likelihood that hard-coded or default cryptographic keys will be introduced or left unprotected.

prevents

Explicit prohibition of hard-coded passwords and unauthenticated external services stops credentials from being embedded directly in source code.

prevents

Contractual requirements for secure coding practices and evidence of testing make it less likely that hard-coded credentials will be introduced or remain undetected in delivered code.

none

Requiring independent oversight and timely disabling of non-human identities makes it harder for hard-coded or long-lived credentials to remain exploitable.

none

Mandating immediate replacement of vendor-supplied default credentials eliminates the use of hard-coded or factory passwords that attackers can trivially obtain from documentation or firmware.
