Adobe Connect <= 11.0.5 Multiple Vulnerabilities (APSB21-19)

high Nessus Plugin ID 147419

Language:

Synopsis

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

Description

The version of Adobe Connect installed on the remote host is prior to 11.2.0. It is, therefore, affected by multiple vulnerabilities as referenced in the apsb21-19 advisory.

 - Adobe Connect version 11.0.7 (and earlier) is affected by an Input Validation vulnerability in the export feature. An attacker could exploit this vulnerability by injecting a payload into an online event form and achieve code execution if the victim exports and opens the data on their local machine. (CVE-2021-21085)

 - Adobe Connect version 11.0.7 (and earlier) is affected by a reflected Cross-Site Scripting (XSS) vulnerability. An attacker could exploit this vulnerability to inject malicious JavaScript content that may be executed within the context of the victim's browser when they browse to the page containing the vulnerable field. (CVE-2021-21079, CVE-2021-21080)

 - Reflected cross-site scripting potentially leading to Arbitrary JavaScript execution in the browser (CVE-2021-21081)

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 11.2.0 or later.
