CVE-2012-4847
IBM Cognos Business Intelligence (BI) 8.4 and 8.4.1 allows remote authenticated users to cause a denial of service (CPU consumption) via a crafted request containing a zero-valued byte.
Does this matter?
Lower severity and a low EPSS score (0.97%). Track it; it rarely justifies an emergency change on its own.
