CVE-2018-15393: Cisco Content Security Management Appliance (SMA) Cross-Site Scripting Vulnerability

A vulnerability in the web-based management interface of Cisco Content Security Management Appliance (SMA) Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a maliciously crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

Security readout for executives and security teams

This flaw affects Cisco Content Security Management Appliance management pages. An attacker must convince a management-interface user to open a crafted link. If successful, browser script could run in that user’s session and expose browser-based sensitive information. The public bundle does not show active exploitation. Exposure is limited to organizations running Cisco Content Security Management Appliance Software with accessible web management interfaces. Business impact depends on who can reach that interface and whether administrators can be persuaded to follow malicious links. Treat as a moderate management-plane risk. Prioritize environments where SMA administration is reachable from broad networks or used by privileged staff. It is not supported as emergency KEV-driven work by the provided evidence. Mitigation focus: Review Cisco advisory cisco-sa-20181107-sma-xss for affected releases and remediation guidance.; Inventory all Cisco SMA deployments and record SMA Software versions.; Restrict SMA management interface access to trusted administrative networks..
