CVE-2017-3768 (GCVE-0-2017-3768)

Vulnerability from cvelistv5 – Published: 2018-01-26 19:00 – Updated: 2024-09-16 22:02

Summary

An unprivileged attacker with connectivity to the IMM2 could cause a denial of service attack on the IMM2 (Versions earlier than 4.4 for Lenovo System x and earlier than 6.4 for IBM System x). Flooding the IMM2 with a high volume of authentication failures via the Common Information Model (CIM) used by LXCA and OneCLI and other tools can exhaust available system memory which can cause the IMM2 to reboot itself until the requests cease.

Severity

No CVSS data available.
