url /zdm/ios/mdm↗

• → Monitor for HTTP PUT requests to the /zdm/ios/mdm endpoint with Content-Type 'application/x-apple-aspen-mdm' and User-Agent 'MDM/1.0', which is the attack vector used in this XXE exploit. ↗
• → Inspect XML payloads sent to /zdm/ios/mdm for DOCTYPE declarations and external entity references (XXE), which are the mechanism of exploitation. ↗
• → Google dork 'inurl:zdm logon' can be used to identify exposed XenMobile instances; monitor for reconnaissance activity matching this pattern against your infrastructure. ↗
• → Watch for outbound DNS/HTTP callbacks from the XenMobile server to external webhook or attacker-controlled URLs, indicative of successful XXE out-of-band data exfiltration. ↗

• · The vulnerability affects XenMobile Server 10.8 before RP2 and 10.7 before RP3. Ensure patched versions (10.8 RP2+ or 10.7 RP3+) are deployed before relying solely on detection. ↗
