A vulnerability in the web proxy functionality of the Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to forward traffic from the web proxy interface of an affected device to the administrative management interface of an affected device, aka an Access Control Bypass Vulnerability. Affected Products: virtual and hardware versions of Cisco Web Security Appliance (WSA). More Information: CSCvd88863. Known Affected Releases: 10.1.0-204 9.0.0-485.

A vulnerability in the web interface of the Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to perform command injection and elevate privileges to root. The attacker must authenticate with valid administrator credentials. Affected Products: Cisco AsyncOS Software 10.0 and later for WSA on both virtual and hardware appliances. More Information: CSCvd88862. Known Affected Releases: 10.1.0-204. Known Fixed Releases: 10.5.1-270 10.1.1-235.

A vulnerability in the web-based management interface of Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. Affected Products: virtual and hardware versions of Cisco Web Security Appliance (WSA). More Information: CSCvd88865. Known Affected Releases: 10.1.0-204.

A vulnerability in AsyncOS for the Cisco Web Security Appliance (WSA) could allow an unauthenticated, local attacker to log in to the device with the privileges of a limited user or an unauthenticated, remote attacker to authenticate to certain areas of the web GUI, aka a Static Credentials Vulnerability. Affected Products: virtual and hardware versions of Cisco Web Security Appliance (WSA). More Information: CSCve06124. Known Affected Releases: 10.1.0-204. Known Fixed Releases: 10.5.1-270.

A vulnerability in the CLI parser of the Cisco Web Security Appliance (WSA) could allow an authenticated, local attacker to perform command injection and elevate privileges to root. The attacker must authenticate with valid operator-level or administrator-level credentials. Affected Products: virtual and hardware versions of Cisco Web Security Appliance (WSA). More Information: CSCvd88855. Known Affected Releases: 10.1.0-204. Known Fixed Releases: 10.5.1-270 10.1.1-234.

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.

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.

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.

A vulnerability in the URL filtering feature of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to bypass a configured URL filter rule. Affected Products: This vulnerability affects all releases prior to the first fixed release of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA), both virtual and hardware appliances, that are configured with URL filters for email scanning. More Information: CSCvc69700. Known Affected Releases: 8.5.3-069 9.1.1-074 9.1.2-010.

A vulnerability in the Multipurpose Internet Mail Extensions (MIME) scanner of Cisco AsyncOS Software for Cisco Email Security Appliances (ESA) and Web Security Appliances (WSA) could allow an unauthenticated, remote attacker to bypass configured user filters on the device. Affected Products: This vulnerability affects all releases prior to the first fixed release of Cisco AsyncOS Software for Cisco ESA and Cisco WSA, both virtual and hardware appliances, that are configured with message or content filters to scan incoming email attachments on the ESA or services scanning content of web access on the WSA. More Information: SCvb91473, CSCvc76500. Known Affected Releases: 10.0.0-203 9.9.9-894 WSA10.0.0-233.
