CVE-2024-21988Network attack vector

Sensitive-information disclosure via complex SSH interception

Published Jun 14, 2024 · Updated Nov 12, 2024

Information disclosure in NetApp StorageGRID before 11.7.0.9 and 11.8.0.5 allows man-in-the-middle attackers to read sensitive data. The flaw is in the SSH cryptographic implementation, but NetApp has not disclosed the affected routine or the cryptographic operation that mishandles untrusted traffic. Exploitation requires a complex network-position attack and user interaction; the reported consequence is confidentiality loss without data modification or service interruption.
