CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') - CVE-2016-5653

According to the reporter, an authenticated but low privileged user may exploit a SQL Injection in the "ID" and "Branch" parameters of a search and enumerate the full database.

CWE-280: Improper Handling of Insufficient Permissions or Privileges - CVE-2016-5654

According to the reporter, a remote authenticated attacker able to execute a man-in-the-middle attack may be able to tamper with the "xmlMessageOut" parameter of a client POST request to escalate privileges to administrator.

CWE-295: Improper Certificate Validation - CVE-2016-5655

According to the reporter, a remote unauthenticated attacker able to execute a man-in-the-middle attack may be able to present an alternate SSL certificate and therefore decrypt all traffic between the client and FusionCapital Opics Plus server.

Misys has responded to these issues with the following statement:

Misys has analysed the reported vulnerabilities and determined that they could
relate to a specific older version, but not for all versions, of one of our
applications, with the matter being rectified with a user configuration change
or non-emergency software patch.  In short, we identified that the sql
injection vulnerability is true positive and the other two reported
vulnerabilities are misconfigurations.  For more information, our Opics clients
are being directed to contact their Misys Customer Advocate.

An authenticated attacker may be able escalate privileges to administrator, or perform full searches on the database. An unauthenticated attacker may be able decrypt SSL traffic between the client and server.

The CERT/CC is currently unaware of a practical solution to this problem.

Restrict Network Access

As a general good security practice, only allow connections from trusted hosts and networks. Consult your firewall product's manual for more information.
