  /userentry.

  - CVE-2015-2994: A vulnerability exists in the ChangePhoto.jsp in the administrator portal, which
  does not handle correctly directory traversal sequences and does not enforce file extension
  restrictions.

  - CVE-2015-2998: SysAid Help Desktop Software uses a hard-coded encryption key.

  - CVE-2015-2999: A SQL injection vulnerability exists in genericreport, HelpDesk.jsp and
  RFCGantt.jsp.

  - CVE-2015-3000: An XML entity expansion vulnerability exists.

  sets the sa user password to a pre-defined hard-coded password.");

  - A malicious user can decrypt e.g. the database password stored in serverConf.xml.

  - A user with administrative rights can perform a SQL injection attack to read and modify the
  database.

  - A unauthenticated attacker can create a Denial of Service condition for 10+ seconds. Repeating
  this will slow down the server extensively.

  - An attacker can gain administrative access to the built-in SQL Server Express.");
