Vulnerability Details  
Every user has the ability to execute SQL queries through the  
"/event/" script, including the default "guest" user. (The SQL  
query option is just not visible in the web interface)  
Below is the POST request, executed as "guest":  
POST /event/ HTTP/1.1  
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8  
Accept-Language: en-US,en;q=0.5  
Accept-Encoding: gzip, deflate  
Connection: keep-alive  
Content-Type: application/x-www-form-urlencoded  
Content-Length: 39  
Access to queries starting with "INSERT" or "UPDATE" is denied by default,  
however this can be bypassed by doing a select query first, like this:  
The included Postgres backend is running with SYSTEM privileges on Windows,  
allowing to write files to disk with these privileges.  
A Metasploit exploit module will be released shortly.  
ManageEngine has provided a patch to fix this issue, the steps to apply/fix  
this are as below:  
1. Stop the ELA service.  
2. Download the zip from  
and extract the folders. You would have two folders "EventLogAnalyzerJSP"  
and "LogAnalyzerClient" under "o_19q686iqs1sfemdf19e05sqre61". Copy these  
two folders and place it under <ELA Home>//lib/ folder.  
3. The path of the following files would be as below:  
runQuery_jsp.class --> <ELA  
RunQuery.class --> <ELA Home>\\lib\\LogAnalyzerClient\\com\\adventnet\\la\  
4. Restart the ELA service and check for the issue.
