A cross-site scripting (XSS) vulnerability in Trend Micro InterScan Web Security Virtual Appliance 6.5 SP2 could allow an attacker to tamper with the web interface of the product in a manner separate from the similar CVE-2020-8462.

A command injection vulnerability in ModifyVLANItem of Trend Micro InterScan Web Security Virtual Appliance 6.5 SP2 could allow an authenticated, remote attacker to send specially crafted HTTP messages and execute arbitrary OS commands with elevated privileges.

A command injection vulnerability in AddVLANItem of Trend Micro InterScan Web Security Virtual Appliance 6.5 SP2 could allow an authenticated, remote attacker to send specially crafted HTTP messages and execute arbitrary OS commands with elevated privileges.

A vulnerability in Trend Micro InterScan Web Security Virtual Appliance 6.5 SP2 could allow an authenticated, remote attacker to send a specially crafted HTTP message and achieve remote code execution with elevated privileges.

A vulnerability in Trend Micro InterScan Web Security Virtual Appliance 6.5 SP2 could allow an unauthenticated, remote attacker to send a specially crafted HTTP message and achieve remote code execution with elevated privileges.

A vulnerability in Trend Micro InterScan Web Security Virtual Appliance 6.5 may allow remote attackers to bypass authentication on affected installations of Trend Micro InterScan Web Security Virtual Appliance.

A vulnerability in Trend Micro InterScan Web Security Virtual Appliance 6.5 may allow remote attackers to execute arbitrary code on affected installations. Authentication is required to exploit this vulnerability.

A vulnerability in Trend Micro InterScan Web Security Virtual Appliance 6.5 may allow remote attackers to disclose sensitive informatoin on affected installations.

A cross-site scripting vulnerability (XSS) in Trend Micro InterScan Web Security Virtual Appliance 6.5 may allow a remote attacker to tamper with the web interface of affected installations. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

A vulnerability in Trend Micro InterScan Web Security Virtual Appliance version 6.5 SP2 could allow an non-authorized user to disclose administrative credentials. An attacker must be an authenticated user in order to exploit the vulnerability.

Trend Micro InterScan Web Security Virtual Appliance (IWSVA) 6.5 before CP 1746 does not sanitize a rest/commonlog/report/template name field, which allows a 'Reports Only' user to inject malicious JavaScript while creating a new report. Additionally, IWSVA implements incorrect access control that allows any authenticated, remote user (even with low privileges like 'Auditor') to create or modify reports, and consequently take advantage of this XSS vulnerability. The JavaScript is executed when victims visit reports or auditlog pages.

Trend Micro InterScan Web Security Virtual Appliance (IWSVA) 6.5 before CP 1746 mismanages certain key and certificate data. Per IWSVA documentation, by default, IWSVA acts as a private Certificate Authority (CA) and dynamically generates digital certificates that are sent to client browsers to complete a secure passage for HTTPS connections. It also allows administrators to upload their own certificates signed by a root CA. An attacker with low privileges can download the current CA certificate and Private Key (either the default ones or ones uploaded by administrators) and use those to decrypt HTTPS traffic, thus compromising confidentiality. Also, the default Private Key on this appliance is encrypted with a very weak passphrase. If an appliance uses the default Certificate and Private Key provided by Trend Micro, an attacker can simply download these and decrypt the Private Key using the default/weak passphrase.

Multiple Access Control issues in Trend Micro InterScan Web Security Virtual Appliance (IWSVA) 6.5 before CP 1746 allow an authenticated, remote user with low privileges like 'Reports Only' or 'Auditor' to change FTP Access Control Settings, create or modify reports, or upload an HTTPS Decryption Certificate and Private Key.
