Adobe Connect < 11.2.3 Privilege Escalation (ASPB21-66)

medium Nessus Plugin ID 152487
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote web server contains an application that is affected by multiple vulnerabilities.

Description

The version of Adobe Connect running on the remote host is 11.2.2 or earlier. It is, therefore, affected by multiple vulnerabilities.

- Violation of secure design principles, resulting on a security feature bypass. (CVE-2021-36061)

- Cross-site Scripting (reflected XSS), resulting on an arbitrary code execution. (CVE-2021-36062, CVE-2021-36063)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Adobe Connect version 11.2.3 or later
