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.

An SQL Injection vulnerability exists in the GetServiceByRestaurantID endpoint of the Aptsys gemscms POS Platform backend thru 2025-05-28. The vulnerability arises because user input is directly inserted into a dynamic SQL query syntax without proper sanitization or parameterization. This allows an attacker to inject and execute arbitrary SQL code by submitting crafted input in the id parameter, leading to unauthorized data access or modification.

A vulnerability exists in the Aptsys POS Platform Web Services module thru 2025-05-28, which exposes internal API testing tools to unauthenticated users. By accessing specific URLs, an attacker is presented with a directory-style index listing all available backend services and POS web services, each with an HTML form for submitting test input. These panels are intended for developer use, but are accessible in production environments with no authentication or session validation. This grants any external actor the ability to discover, test, and execute API endpoints that perform critical functions including but not limited to user transaction retrieval, credit adjustments, POS actions, and internal data queries.

A vulnerability in the PHP backend of gemscms.aptsys.com.sg thru 2025-05-28 allows unauthenticated remote attackers to trigger detailed error messages that disclose internal file paths, code snippets, and stack traces. This occurs when specially crafted HTTP GET/POST requests are sent to public API endpoints, exposing potentially sensitive information useful for further exploitation. This issue is classified under CWE-209: Information Exposure Through an Error Message.
