Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An information disclosure vulnerability exists in the /srvs/membersrv/getCashiers endpoint of the Aptsys gemscms backend platform thru 2025-05-28. This unauthenticated endpoint returns a list of cashier accounts, including names, email addresses, usernames, and passwords hashed using MD5. As MD5 is a broken cryptographic function, the hashes can be easily reversed using public tools, exposing user credentials in plaintext. This allows remote attackers to perform unauthorized logins and potentially gain access to sensitive POS operations or backend functions.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

An unauthenticated information disclosure vulnerability exists in the /srvs/membersrv/getCashiers endpoint of the Aptsys gemscms backend platform (all versions through 2025-05-28). The endpoint returns cashier account data including names, email addresses, usernames, and MD5-hashed passwords. Since MD5 is cryptographically broken, these hashes can be trivially reversed using publicly available tools, exposing plaintext credentials and allowing unauthorized access to POS operations or backend functions.

MitigationImmediately restrict access to the /srvs/membersrv/getCashiers endpoint by implementing proper authentication and authorization controls. Replace MD5 with a strong password hashing algorithm (e.g., bcrypt, Argon2) and force password resets for all affected cashier accounts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify if the getCashiers endpoint is accessible without authentication
    Send an HTTP GET request to /srvs/membersrv/getCashiers on your gemscms server without providing any authentication credentials. Observe whether the request succeeds with a 200 OK response or fails with 401/403.
    Affected if The endpoint returns a 200 OK response with data instead of requiring authentication.
  2. Confirm the endpoint returns cashier account data
    Examine the JSON response from the /srvs/membersrv/getCashiers endpoint. Look for fields that contain cashier information such as names, email addresses, usernames, or password-related fields.
    Affected if The response contains cashier records with personal identifiers or authentication credentials.
  3. Identify if password hashes are present in the response
    Inspect the response for fields containing hash values associated with user accounts. MD5 hashes appear as 32-character hexadecimal strings.
    Affected if Password hash fields are present in the cashier data response.
  4. Determine if hashes are using MD5
    Examine the length and format of the password hash values. MD5 produces 32-character hexadecimal strings (e.g., 5d41402abc4b2a76b9719d911017c592). Verify the format matches MD5 characteristics.
    Affected if Password fields contain 32-character hexadecimal strings consistent with MD5 hashing.

Your environment is affected if the /srvs/membersrv/getCashiers endpoint is accessible without authentication and returns cashier data including MD5-hashed passwords.

Interim mitigation

Immediately restrict access to the /srvs/membersrv/getCashiers endpoint by implementing proper authentication and authorization controls. Replace MD5 with a strong password hashing algorithm (e.g., bcrypt, Argon2) and force password resets for all affected cashier accounts.
