🇸🇦 Saudi Arabia Impact Assessment
ServiceDesk Plus is widely deployed across Saudi government ministries, healthcare institutions, telecom providers (STC, Mobily, Zain), and energy sector organizations including ARAMCO affiliates as an IT service management (ITSM) platform. Successful exploitation could allow attackers to upload web shells and gain persistent access to internal IT infrastructure, potentially pivoting to critical OT/IT networks. Government entities under NCA oversight and financial institutions regulated by SAMA are at high risk given the platform's privileged access to IT ticketing, asset management, and employee data. Healthcare organizations using SDP for helpdesk operations could face patient data exposure violating PDPL compliance requirements.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all instances of Zoho ManageEngine ServiceDesk Plus in your environment using asset inventory.
2. Isolate internet-facing SDP instances behind a WAF or VPN immediately.
3. Disable login page customization feature if not required.
PATCHING GUIDANCE:
4. Upgrade to ServiceDesk Plus version 10.0 build 10012 or later which addresses this vulnerability.
5. Verify patch integrity using Zoho's official checksums before deployment.
6. Apply patches in a staged manner: test environment first, then production.
COMPENSATING CONTROLS:
7. Restrict access to the SDP login page to trusted IP ranges only via firewall ACLs.
8. Deploy a Web Application Firewall (WAF) with rules to block suspicious file upload attempts.
9. Monitor upload directories for unexpected file types (.php, .jsp, .aspx, .sh).
10. Disable file upload functionality at the web server level if not operationally required.
DETECTION RULES:
11. Create SIEM alerts for POST requests to /CustomLogin or login customization endpoints.
12. Monitor for new files created in web-accessible directories on SDP servers.
13. Alert on execution of processes spawned by the SDP web server process (e.g., cmd.exe, /bin/sh).
14. Review web server access logs for anomalous file upload patterns from external IPs.
15. Deploy file integrity monitoring (FIM) on SDP installation directories.
