What is CVE-2019-19702?

The modoboa-dmarc plugin version 1.1.0 for Modoboa is susceptible to an XML External Entity Injection (XXE) attack. This vulnerability arises during the processing of XML data, enabling a remote attacker to manipulate XML documents sent to the DMARC reporting address specified in the rua field. By referencing sensitive files such as /dev/random in these documents, the attacker could potentially disrupt the DMARC reporting functionality, leading to a denial of service.
