Multiple Vulnerabilities in Adobe Products Could Allow for Arbitrary Code Execution

Multiple vulnerabilities have been discovered in Adobe Products, the most severe of which could allow for arbitrary code execution.

• Connect is a suite of software for remote training, web conferencing, presentation, and desktop sharing.
• Magento is a leading provider of cloud commerce innovation to merchants and brands across B2C and B2B industries.

Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. 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.

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

Multiple vulnerabilities have been discovered in Adobe Products, the most severe of which could allow for arbitrary code execution. Details of these vulnerabilities are as follows:
Adobe Connect

• Improper Access Control, which could allow for arbitrary code execution. (CVE-2021-36036)
• Improper Authorization, which could allow for security feature bypass. (CVE-2021-36029, CVE-2021-36037)
• Improper Input Validation, which could allow for application denial of service. (CVE-2021-36044)
• Improper Input Validation, which could allow for privilege escalation. (CVE-2021-36032)
• Improper Input Validation, which could allow for security feature bypass. (CVE-2021-36030, CVE-2021-36038)

• Path Traversal, which could allow for arbitrary code execution. (CVE-2021-36031)
• OS Command Injection, which could allow for arbitrary code execution. (CVE-2021-36022, CVE-2021-36023)
• Incorrect Authorization, which could allow for arbitrary file system. (CVE-2021-36039)
• Server-Side Request Forgery, which could allow for arbitrary code execution. (CVE-2021-36043)
• XML Injection, which could allow for arbitrary code execution. (CVE-2021-36020, CVE-2021-36028, CVE-2021-36033)

Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution. 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.

We recommend the following actions be taken:

• Install the updates provided by Adobe 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 un-trusted websites or follow links provided by unknown or un-trusted 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.
