CVE-2013-3993

IBM InfoSphere BigInsights Invalid Input Vulnerability. Exploitation in the wild is confirmed by CISA, not predicted, and the vulnerability is known to be used in ransomware campaigns. Federal agencies were required to remediate by 2022-06-15 (that deadline has passed); treat that date as the outer bound for your own environment. Check the vendor security advisory for the fix.

Senserva AI Opinion for CVE-2013-3993

This is an input validation flaw in certain APIs of IBM InfoSphere BigInsights, IBM's Hadoop-based big data platform, that lets attackers read, write, modify, or delete data without proper authorization. Despite a Medium severity rating (CVSS 6.5) and only a 5 percent EPSS score, it is confirmed on CISA's KEV list since 2022-05-25 and has been used in ransomware campaigns, so the low numbers understate the real-world risk. Anyone still running BigInsights clusters, especially with exposed API endpoints, is exposed to data theft and destruction.

Do this: Apply IBM's patch for CVE-2013-3993 to all BigInsights instances and restrict network access to the affected API endpoints immediately.
