Workarounds and Mitigations

The IBM Cognos Analytics team have developed a “no-upgrade” option for our “On Prem” (local installation) customers.

The single version of the patch is applicable to IBM Cognos Analytics versions 11.0.6 to 11.0.13 FP4, 11.1.x and 11.2.x.



The log4jSafeAgent file that is provided for Cognos Analytics modifies the class byte code at the Java startup time. It removes the vulnerable JNDI lookup, and enforces the StrSubstitutor recursion limit without altering the installed product.

It effectively rewrites the “org/apache/logging/log4j/core/lookup/JndiLookup” class to remove its content during IBM Cognos Analytics start up.
