What it detects

This rule detects web requests carrying the X-ORACLE-DMS-ECID header used as an activation trigger by the SAGEWAVE servlet-filter web shell deployed against Oracle E-Business Suite. Requiring this uncommon header gates the malicious filter so only the operator can invoke it, indicating covert post-exploitation access.
