Multiple Vulnerabilities in Adobe Photoshop, ColdFusion, and Bridge Identified

Multiple Vulnerabilities in Adobe Photoshop, ColdFusion, and Bridge Identified

A cybersecurity advisory was issued yesterday, March 18, 2020, regarding multiple vulnerabilities in Adobe Photoshop, ColdFusion, and Bridge. The vulnerabilities could allow a malicious individual to execute arbitrary code which could potentially lead to a breach.

What It Is:
Multiple vulnerabilities have been discovered in Adobe Photoshop, ColdFusion, and Bridge that could allow for arbitrary code execution. Adobe Photoshop is a graphics editor program. Adobe Bridge is a file management application that manages files across multiple Adobe programs. 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 gaining the same privileges as the logged-on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Technical Summary:
Multiple vulnerabilities have been discovered in Adobe Photoshop, ColdFusion, and Bridge that could allow for arbitrary code execution. The vulnerabilities are as follows:

• Out-of-bounds write vulnerability could allow for Arbitrary Code Execution. (CVE-2020-9551)
• Heap-based buffer overflow vulnerability could allow for Arbitrary Code Execution. (CVE-2020-9552)
• Remote file read vulnerability could allow for Arbitrary File Read from the ColdFusion install directory. (CVE-2020-3761)
• File inclusion vulnerability could allow for Arbitrary Code Execution of files located in the webroot or its subdirectory (CVE-2020-3794)
• Heap corruption vulnerability that could allow for Arbitrary Code Execution. (CVE-2020-3783)
• Multiple Memory corruption vulnerabilities that could allow for Arbitrary Code Execution. (CVE-2020-3784, CVE-2020-3785, CVE-2020-3786, CVE-2020-3787, CVE-2020-3788, CVE-2020-3789, CVE-2020-3790)
• Multiple Out-of-bounds read vulnerabilities that could allow for Information Disclosure. (CVE-2020-3771, CVE-2020-3777, CVE-2020-3778, CVE-2020-3781, CVE-2020-3782, CVE-2020-3791)

• Multiple Buffer errors vulnerabilities that could allow for Arbitrary Code Execution. (CVE-2020-3770, CVE-2020-3772, CVE-2020-3774, CVE-2020-3775, CVE-2020-3776, CVE-2020-3780)

What To Do:
We recommend the following actions be taken:

• Install updates provided by Adobe and related Coldfusion JDK/JRE versions immediately after appropriate testing.
• 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 untrusted sources.
• Apply the Principle of Least Privilege to all systems and services.

Negative Consequences of Lost or Stolen Data:
The loss or theft of proprietary data can have severe impacts, particularly if the compromise becomes public and sensitive information is exposed. Possible impacts include:

• Temporary or permanent loss of sensitive or proprietary information.
• Disruption to regular operations.
• Financial losses incurred to restore systems and files.
• Potential harm to an organization’s reputation.
