Multiple Vulnerabilities in Adobe ColdFusion Could Allow for Arbitrary Code Execution (APSB19-47)

MS-ISAC ADVISORY NUMBER:

2019-097

DATE(S) ISSUED:

09/25/2019

OVERVIEW:

Multiple vulnerabilities have been discovered in Adobe ColdFusion, the most severe of which could allow for arbitrary code execution. Adobe ColdFusion is a rapid web-application development platform used to create and maintain web applications. Successful exploitation of the most severe of these vulnerabilities could result in an attacker executing arbitrary code in the context of the affected application. Depending on the privileges associated with this application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of this vulnerability could have less impact than if it was configured with administrative rights.

THREAT INTELLIGENCE:

There are no reports of these vulnerabilities being exploited in the wild.

SYSTEMS AFFECTED:

  • Adobe ColdFusion 2018 update 4 and earlier
  • Adobe ColdFusion 2016 update 11 and earlier

RISK:

Government:
  • Large and medium government entities: HIGH
  • Small government entities: MEDIUM
Businesses:
  • Large and medium business entities: HIGH
  • Small business entities: MEDIUM
Home Users:
LOW

TECHNICAL SUMMARY:

Multiple vulnerabilities have been discovered in Adobe ColdFusion, the most severe of which could allow for arbitrary code execution. Details of these vulnerabilities are included below:

  • A Security bypass vulnerability that could allow for Information Disclosure. (CVE-2019-8072)
  • A Command Injection via Vulnerable component that could allow for Arbitrary Code Execution. (CVE-2019-8073)
  • A Path Traversal vulnerability that could allow for Access Control Bypass. (CVE-2019-8074)

NOTE: Additional JEE, Java Enterprise Edition, and JDK, Java Development Kit, requirements must be met in addition to applying patches.

Successful exploitation of the most severe of these vulnerabilities could result in an attacker executing arbitrary code in the context of the affected application. Depending on the privileges associated with this application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of this vulnerability could have less impact than if it was configured with administrative rights.

RECOMMENDATIONS:

We recommend the following actions be taken:

  • Install the updates provided by Adobe immediately after appropriate testing.
  • Ensure JDK, Java Development Kit, and JEE, Java Enterprise Edition, requirements and/or configuration changes are met after applying patches.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to visit websites or follow links provided by unknown or untrusted sources.
  • Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from un-trusted sources.
  • Apply the Principle of Least Privilege to all systems and services.
