Details

Christina Fu discovered that Dogtag PKI accidentally enabled a mock
authentication plugin by default. An attacker could potentially use
this flaw to bypass the regular authentication process and trick the
CA server into issuing certificates. This issue only affected Ubuntu
16.04 LTS. (CVE-2017-7537)

It was discovered that Dogtag PKI did not properly sanitize user
input. An attacker could possibly use this issue to perform cross site
scripting and obtain sensitive information. This issue only affected
Ubuntu 22.04 LTS. (CVE-2020-25715)

It was discovered that the XML parser did not properly handle entity
expansion. A remote attacker could potentially retrieve the content of
arbitrary files by sending specially crafted HTTP requests. This issue
only affected Ubuntu 16.04 LTS. (CVE-2022-2414)
