Details

OpenClinic GA is an open source fully integrated hospital management solution.

Multiple SQL injection vulnerabilities exist in the listImmoLabels.jsp page of OpenClinic GA. These vulnerabilities are the result of dynamic use of parameters in prepared statements as seen in the souce code of listImmoLabels.jsp below:

	<%
//*** FIND *************************************************
if(sAction.equalsIgnoreCase("find")){		
	String sSql = "select * from OC_IMMO where 1 = 1 ";
	
	if(sImmoService.length() > 0){
		sSql+= "and OC_IMMO_SERVICEUID like '"+sImmoService+"%'";
	}
	if(sImmoLocation.length() > 0){
		sSql+= "and OC_IMMO_LOCATION like '"+sImmoLocation+"%'";
	}
	if(sImmoCode.length() > 0){
		sSql+= "and OC_IMMO_CODE like '"+sImmoCode+"%'";
	}
	if(sImmoBuyer.length() > 0){
		sSql+= "and OC_IMMO_BUYER like '"+sImmoBuyer+"%'";
	}
	if(sImmoComment.length() > 0){
		sSql+= "and OC_IMMO_COMMENT like '%"+sImmoComment+"%'";
	}
	
	Debug.println(sSql);
	PreparedStatement ps = oc_conn.prepareStatement(sSql);
	ResultSet rs = ps.executeQuery();

	String sService, sLocation, sCode, sBuyer, sComment, sClass = "";
	int recordCount = 0;
    %>

The above code results in the following vulnerabilities.
