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.","published":"2018-01-26T19:29:00.000Z","lastModified":"2026-06-17T01:18:54.000Z","status":"Modified","sourceIdentifier":"psirt@lenovo.com","cvss":{"version":"3.0","score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-400"],"affected":["lenova/flex system x240 m5 firmware","lenova/flex system x280 x6 firmware","lenova/flex system x440 m4 firmware","lenova/flex system x480 x6 firmware","lenova/flex system x880 firmware","lenova/nextscale nx360 m5 firmware","lenova/system x3250 m6 firmware","lenova/system x3500 m5 firmware","lenova/system x3550 m5 firmware","lenova/system x3650 m5 firmware","lenova/system x3750 m4 firmware","lenova/system x3850 x6 firmware","lenova/system x3950 x6 firmware","lenova/flex system x240 m4 firmware","ibm/bladecenter hs22 firmware","ibm/bladecenter hs23 firmware","ibm/bladecenter hs23e firmware","ibm/flex system x220 m4 firmware","ibm/flex system x222 m4 firmware","ibm/flex system x240 m4 firmware","ibm/flex system x280 m4 firmware","ibm/flex system x440 m4 firmware","ibm/flex system x480 m4 firmware","ibm/flex system x880 m4 firmware","ibm/idataplex dx360 m4 firmware","ibm/idataplex dx360 m4 water cooled firmware","ibm/nextscale nx360 m4 firmware","ibm/system x3100 m4 firmware","ibm/system x3100 m5 firmware","ibm/system x3250 m4 firmware","ibm/system x3250 m5 firmware","ibm/system x3300 m4 firmware","ibm/system x3500 m4 firmware","ibm/system x3530 m4 firmware","ibm/system x3550 m4 firmware","ibm/system x3630 m4 firmware","ibm/system x3650 m4 firmware","ibm/system x3650 m4 bd firmware","ibm/system x3750 m4 firmware","ibm/system x3850 x6 firmware","ibm/system x3950 x6 firmware","ibm/system x3650 m4 hd firmware"],"epss":{"score":0.01212,"percentile":0.68349,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.21%).
