Apache Tomcat Oracle SQL injection flaw under active exploitation
Vulnerability
Summary
Hide ▲
Show ▼
SQL injection in a public-facing Java application running Apache Tomcat let attackers reach an Oracle database and load the khunt toolkit as database-stored Java objects rather than as files on disk. Huntress tied the activity to July 27, 2026, after credential-theft detections fired and requests were traced to 178.162.151[.]229. The attackers used KhuntCmd to run cmd.exe /c whoami and confirmed SYSTEM-level access on the underlying Windows server. They also used the toolkit to browse files, read hashes, and stage the SAM, SECURITY, and SYSTEM registry hives, while Huntress did not confirm exfiltration.

Credential theft is detected on an Oracle database server
Detection Ioc UpdateHuntress detected credential theft on July 27, 2026 on a server hosting an Oracle database server after Apache access logs showed attackers reached a vulnerable search engine endpoint and autocomplete search feature in a public-facing Java application running Apache Tomcat. The requests were traced to 178.162.151[.]229, and the SQL injection path let the attackers issue SQL commands to the Oracle database.

khunt is embedded directly inside Oracle as a Java object
Technical Analysis UpdateHuntress detailed that after SQL injection, the attackers stored the khunt toolkit directly inside Oracle as a Java object rather than deploying executable files on the server, then used KhuntCmd to run cmd.exe /c whoami and confirm SYSTEM-level permissions on the Windows server. The toolkit also included KhuntHash for writing usernames and password data, KhuntFS and KhuntFS2 for file browsing and search, KhuntT for installation checks, and KhuntUnzip for extracting compressed files; the attackers also copied the SAM, SECURITY, and SYSTEM registry hives and ran tasklist /svc to enumerate services.
