Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: OpenEMR leaks the `gateway_api_key` in plaintext to the client.โฆ
๐ก๏ธ **CWE**: CWE-200 (Information Exposure). ๐ **Flaw**: The application fails to mask the API key in at least two specific code paths, sending it directly to the frontend in clear text. ๐
Q3Who is affected? (Versions/Components)
๐ฅ **Vendor**: OpenEMR (Open Source Medical System). ๐ฆ **Affected Versions**: Versions 5.0.2 through 8.0.0 (prior to the fix). โ ๏ธ Check your deployment version immediately! ๐
Q4What can hackers do? (Privileges/Data)
๐ป **Privileges**: Requires Low Privilege (PR:L). ๐ต๏ธ **Data Access**: Hackers can retrieve the `gateway_api_key`. ๐ฏ **Impact**: Full compromise of payment gateway accounts, enabling financial fraud and data theft. ๐ณ
Q5Is exploitation threshold high? (Auth/Config)
โ๏ธ **Threshold**: Low. ๐ถ **Network**: Network Accessible (AV:N). ๐ **Auth**: Requires Low Privileges (PR:L) - meaning a basic authenticated user can exploit this. ๐ช No User Interaction needed (UI:N). ๐
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ซ **Public Exp**: No public PoC or Exploit code provided in the data. ๐ **References**: Only GitHub commit links and security advisories are available. ๐ Stay vigilant but no ready-made scripts exist yet. ๐
Q7How to self-check? (Features/Scanning)
๐ **Check**: Inspect network traffic for plaintext `gateway_api_key` in responses. ๐ **Code Scan**: Look at `interface/patient_file/front_payment.php` (Line 765) and `portal/portal_payment.php` (Line 537).โฆ
โ **Fixed**: Yes! A fix is available via GitHub commit `fe6341496dc82d5b4f5a3f35891bb2e2481f3b25`. ๐ ๏ธ **Action**: Update to the latest version or apply the specific patch referenced in the GHSA advisory. ๐
Q9What if no patch? (Workaround)
๐ง **Workaround**: If patching is delayed, restrict access to payment-related endpoints. ๐ **Mitigation**: Implement strict WAF rules to block requests attempting to extract API keys.โฆ
