CVE-2021-44207

What it actually does

Acclaim USAHERDS through version 7.4.0.1 contains hard-coded credentials. An attacker who obtains or knows those credentials can authenticate without needing a legitimate user account, potentially gaining access to application functions, backend services, or data stores protected by those shared credentials. Because the same embedded credentials may exist across deployments and cannot be reliably rotated without a vendor-side fix, compromise can lead to confidentiality, integrity, and availability impact across affected systems.

Why it matters to the business

Successful exploitation can allow unauthorized access to sensitive animal health, regulatory, operational, or administrative data managed by USAHERDS, and may let an attacker alter records or disrupt service availability. The vulnerability is listed in CISA KEV with a remediation due date of 2025-01-13 and is marked as actively exploited in the wild, so organizations using affected versions should treat exposure as urgent even though the vulnerability is older.

How an attack unfolds

An attacker first identifies an exposed or reachable USAHERDS deployment. They then obtain the hard-coded credentials from public exploit information, reverse engineering, leaked configuration, shared binaries, or prior compromise. Using those credentials, the attacker authenticates directly to the application, service endpoint, or backend component that accepts them. After authentication, the attacker enumerates accessible functionality and data, performs unauthorized reads or changes, and may establish persistence by creating new accounts, changing configuration, exporting data, or using the access to pivot to adjacent systems. Because the credentials are hard-coded, simply changing local passwords may not fully remediate the issue unless the vulnerable software is updated or the credential path is disabled.

How to fix it

Upgrade Acclaim USAHERDS to a vendor-supported version that removes the hard-coded credential behavior. No specific fixed version was provided in the input, so organizations should obtain remediation guidance directly from Acclaim Systems and verify that versions later than 7.4.0.1 are not vulnerable. If an upgrade is not immediately available, restrict network access to USAHERDS and any dependent services to trusted administrative networks, block public internet exposure, disable or remove any shared/default accounts where supported, rotate all related application, service, and database credentials, and monitor for use of legacy credential paths. Because hard-coded credentials may be embedded in the product, compensating controls should be considered temporary until a vendor fix is applied.

How to confirm the fix worked

Confirm the deployed USAHERDS version is not 7.4.0.1 or earlier and validate with the vendor that the installed build removes the hard-coded credentials. Test that the formerly hard-coded credential no longer authenticates to the application or dependent services. Review configuration files, service accounts, database accounts, and application authentication paths to ensure no shared vendor-default credentials remain active. Validate that USAHERDS administrative and service interfaces are not exposed to untrusted networks. Re-run external and internal exposure scans after remediation to confirm affected endpoints are no longer reachable except from approved segments.

Typical attack path

1. Discover an internet-facing or network-accessible Acclaim USAHERDS instance.
2. Confirm the instance is running an affected version through banners, application behavior, documentation, or fingerprinting.
3. Obtain the hard-coded credential pair or token associated with the vulnerable software.
4. Authenticate to the affected application, service, or backend interface using the hard-coded credentials.
5. Enumerate available privileges, application modules, records, and administrative functions.
6. Access, export, modify, or delete sensitive records depending on the permissions granted to the hard-coded credential.
7. Create additional access paths, alter configuration, or pivot to connected systems if the compromised credential permits it.

How to detect it

Investigate whether hard-coded or shared credentials were used to authenticate to USAHERDS or related backend services. Review application authentication logs, web server access logs, database audit logs, identity provider logs if integrated, operating system event logs, VPN logs, firewall logs, and network flow data. Focus on successful logins not attributable to named users, repeated login attempts against service or default accounts, access from unfamiliar IP addresses, logins outside normal operating windows, requests to administrative functions, large record searches or exports, mass updates, and creation of new users or elevated roles. Correlate authentication events with subsequent data access, configuration changes, database queries, file exports, and outbound network connections. Because public reporting in the provided input does not include the actual credential values, file names, endpoint paths, or actor-specific infrastructure, detection should rely on anomalous use of shared/service credentials and post-authentication behavior rather than a single fixed signature.

What your security team should do

• Prioritize remediation because this vulnerability is in CISA KEV, has active in-the-wild exploitation, and has a KEV due date of 2025-01-13.
• Inventory all Acclaim USAHERDS deployments and identify any running version 7.4.0.1 or earlier.
• Upgrade to a vendor-supported fixed release or obtain a vendor hotfix that removes the hard-coded credential behavior.
• Immediately restrict network access to USAHERDS application, administrative, service, and backend interfaces until patching is complete.
• Rotate all credentials associated with the USAHERDS application, connected databases, service accounts, and integration accounts after applying the fix.
• Review authentication logs for successful or failed logins from unusual IP addresses, unexpected user agents, non-business hours, or accounts not tied to named users.
• Look for suspicious administrative activity, new accounts, permission changes, bulk exports, record modification spikes, and unusual database access following any suspected use of shared credentials.
• If exploitation is suspected, preserve application logs, web server logs, database audit logs, operating system logs, and network flow records before remediation changes overwrite evidence.
