→Exploit payload uses Java gadget with DNS callback via interactsh; detect out-of-band DNS interactions triggered from OFBiz server as evidence of successful deserialization exploitation.
→Response body containing 'value="errorMessage"' combined with a DNS interaction from the target confirms the deserialization vulnerability is triggered.

·Vulnerability affects all Apache OFBiz releases before 17.12.07; upgrade to 17.12.07 or later to remediate. ↗
·The NVD description confirms the unsafe deserialization root cause; no version-specific patch bypass is noted beyond the 17.12.07 fix. ↗
