CVE-2019-13990

The Terracotta Quartz Scheduler is susceptible to an XML external entity attack (XXE) through a job description. This issue stems from inadequate handling of XML external entity (XXE) declarations in the initDocumentParser function within xml/XMLSchedulingDataProcessor.java. By enticing a victim to access a maliciously crafted job description (containing XML content), a remote attacker could exploit this vulnerability to execute an XXE attack on the targeted system.
