The version of Adobe Experience Manager installed on the remote host is affected by multiple vulnerabilities as referenced in the APSB21-15 advisory, including the following:
An improper access control vulnerability exists in Adobe Experience Manager due to improper access checks.
An attacker can exploit this to impose a DoS condition on an affected instance. (CVE-2021-21083)
A stored cross-site scripting (XSS) vulnerability exists in Adobe Experience Manager due to improper validation of user-supplied input before returning it to users. An authenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user’s browser session. (CVE-2021-21084)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
