IBM Engineering Lifecycle Management adopts log4j v2 in all applications (removing log4jv1)



The log4j version 1 vulnerabilities (CVE-2021-4104 and related CVE-2022-23307, CVE-2022-23305, CVE-2022-23302 etc) in IBM Engineering Lifecycle Management (ELM) is being mitigated in ELM version 7.0.2 in Service Release 1 (SR1) and 7.0.1 Service Release 1 (SR1).

Log4j version 1 is being replaced with log4j version 2.17 or later in ELM. Log4j version 1 libraries are not shipped with SR1.


Engineering Lifecycle Management Servers and clients
The following applies to customer use Engineering Workflow Management, Engineering Test Management, DOORS Next, and related applications:
  • Customers on ELM versions before 7.0.2 are encouraged to upgrade to ELM 7.0.2 SR1 iFix 15 or later.
  • Customers currently on ELM version 7.0.2 must perform a side-by-side installation of ELM 7.0.2 SR1 iFix15
  • Customers currently on ELM version 7.0.1 can choose a way to remediate their systems
ELM Server Installation
The installation process for Engineering Lifecycle Management 7.0.2 SR1 (iFix015) and 7.0.1 SR1 (iFix018) is different than the regular interim fix process. Installation is performed by using IBM Installation Manager and existing configuration files are copied to the new Engineering Lifecycle Management installation.
  • Note: The side-by-side installation does not require any database updates or reindexing.
Future interim fixes for Engineering Lifecycle Management 7.0.2 SR1 (iFix015) and 7.0.1 SR1 (iFix018) are to be installed the way interim fixes are traditionally deployed. Future interim fixes are only compatible with Engineering Lifecycle Management 7.0.2 SR1 (iFix015). They are not compatible with earlier versions of ELM. You must move to the SR1 release to use future interim fixes.
Important:  ELM with Log4jv2 uses log4j2.xml instead of Customized log settings must be reapplied by using XML formatting.
