CVE-2019-7666: Prima Systems FlexAir, Versions 2.3.38 and prior.

Prima Systems FlexAir, Versions 2.3.38 and prior. The application allows improper authentication using the MD5 hash value of the password, which may allow an attacker with access to the database to login as admin without decrypting the password.

Security readout for executives and security teams

Plain-English summary

Prima Systems FlexAir 2.3.38 and earlier can treat a stored password hash as enough to authenticate. If someone can access the application database, they may be able to sign in as an administrator without knowing or cracking the real password.

Executive priority

Treat this as a targeted operational technology access-control risk, not a broad internet worm scenario. Prioritize if FlexAir is still deployed, especially where database backups or credentials may be exposed.

Technical view

The CVE describes improper authentication in FlexAir where the MD5 hash value of a password can be used to authenticate. The stated prerequisite is database access. Impact is administrative access to the application; CVSS, CWE, and detailed vendor remediation data are not present in the provided bundle.

Likely exposure

Exposure is limited to environments running Prima Systems FlexAir 2.3.38 or earlier. Risk is higher where the FlexAir database, backups, or stored credential hashes are reachable by operators, service accounts, backups, or compromised adjacent systems.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. The vulnerability requires access to the database first, so it is most relevant after a database exposure, insider misuse, backup leak, or compromise of a system with database privileges.

Researcher notes

The source bundle identifies the flaw and prerequisite but lacks CVSS, CWE, patch details, and complete affected CPE data. Avoid assuming broader Prima product impact beyond FlexAir 2.3.38 and prior.

Mitigation direction

  • Check vendor or Applied Risk guidance for fixed versions and supported remediation.
  • Restrict database access to required service accounts and administrators only.
  • Review database backup locations and remove unnecessary exposed copies.
  • Rotate FlexAir administrator credentials after database exposure is suspected.
  • Monitor administrative logins for unusual source hosts or timing.

Validation and detection

  • Inventory FlexAir deployments and confirm whether versions are 2.3.38 or earlier.
  • Verify database permissions and backup access paths for FlexAir systems.
  • Review logs for administrator logins following database access events.
  • Confirm whether vendor advisories name an upgrade or compensating controls.
