Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: OpenEMR has a **Reflected XSS** vulnerability. π₯ **Consequences**: Attackers can inject malicious scripts via the `pricelevel` parameter.β¦
π‘οΈ **Root Cause**: **CWE-79** (Improper Neutralization of Input During Web Page Generation). π **Flaw**: The `pricelevel` parameter in OpenEMR does not properly sanitize user input.β¦
π₯ **Vendor**: OpenEMR Community. π¦ **Product**: OpenEMR (Open Source Medical Practice Management). π **Affected Versions**: **Prior to 7.0.0.1**. β **Safe**: Version 7.0.0.1 and later are patched.

π΅οΈ **Hackers Can**: Execute arbitrary JavaScript in the context of the victim's browser. πͺ **Data Theft**: Steal session cookies or sensitive patient data displayed on the page.β¦
π **Auth**: Likely requires the victim to be logged into OpenEMR or visit a crafted link. π― **Config**: Exploitation relies on the `pricelevel` parameter being reflected in the response. π **Threshold**: **Low**.β¦
π **Public PoC**: Yes. A Nuclei template exists on GitHub (projectdiscovery/nuclei-templates). π **Wild Exploit**: No widespread automated exploitation reported yet, but the PoC is public and easy to use.β¦
π **Self-Check**: Scan for OpenEMR instances. π§ͺ **Test**: Send a payload via the `pricelevel` parameter and check if it reflects in the HTML without sanitization.β¦
β **Fixed**: Yes. The vulnerability was patched in **version 7.0.0.1**. π **Commit**: See GitHub commit 59458bc15ab0cb556c521de9d5187167d6f88945 for details.β¦
