Plus: Google patches 36 Android vulnerabilities, Cisco fixes three high-severity issues, and VMWare closes two “serious” flaws.

The most serious flaw gives attackers a way to remotely execute code on systems that many organizations use to move data in critical ICS environments, security vendor says.

Multiple vulnerabilities in the web-based management interface of Cisco Common Services Platform Collector (CSPC) Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit these vulnerabilities by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive, browser-based information.

A vulnerability in the web applications of Cisco UCS Director could allow an authenticated, remote attacker to conduct a cross-site scripting attack on an affected system. This vulnerability is due to unsanitized user input. An attacker could exploit this vulnerability by submitting custom JavaScript to affected web applications. A successful exploit could allow the attacker to rewrite web page content, access sensitive information stored in the applications, and alter data by submitting forms.

A vulnerability in the web-based management interface of Cisco Secure Network Analytics, formerly Cisco Stealthwatch Enterprise, could allow an authenticated, remote attacker to execute arbitrary commands as an administrator on the underlying operating system. This vulnerability is due to insufficient user input validation by the web-based management interface of the affected software. An attacker could exploit this vulnerability by injecting arbitrary commands in the web-based management interface. A successful exploit could allow the attacker to make configuration changes on the affected device or cause certain services to restart unexpectedly.

A vulnerability in the web interface of Cisco Enterprise Chat and Email (ECE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input that is processed by the web interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected system. A successful exploit could allow the attacker to execute arbitrary code in the context of the interface or access sensitive, browser-based information. To successfully exploit this vulnerability, an attacker would need valid agent credentials.

Cisco Talos discovered eight vulnerabilities in the Open Automation Software, two of them critical, that pose risk for critical infrastructure networks.

By Jon Munshaw.  Welcome to this week’s edition of the Threat Source newsletter.  Given the recent tragedies in the U.S., I don’t feel it’s appropriate to open by being nostalgic or trying to be witty — let’s just stick to some security news this week.    The one big...

This whitepaper demonstrates leveraging cross site scripting and polyglot exploitation in an exploit called COOLHANDLUKE to violate network segmentation / layer 2 VLAN policies while routing and sending a file between isolated, air gapped networks without a router. This issue affects HPE Procurve, Aruba Networks, Cisco, Dell, and Netgear products.

In this whitepaper, the author demonstrates abusing persistent cross site scripting and polyglot payloads can allow for robust protocol creation similar to COOLHANDLUKE and allows an attacker to exfiltrate, encapsulate, and tunnel their malicious traffic between IPv4 and IPv6 networks without a router. The author calls the technique and protocol "DIRECTIVEFOUR". This issue affects Cisco SMB and Sx Series switches.
