CVE-2018-15440: Cisco Identity Services Engine Multiple Cross-Site Scripting Vulnerabilities

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web interface of an affected system. The vulnerability is due to insufficient sanitization of user-supplied data that is written to log files and displayed in certain web pages of the web-based management interface of an affected device. An attacker could exploit this vulnerability by convincing a user of the interface to click a specific link or view an affected log file. The injected script code may be executed in the context of the web-based management interface or allow the attacker to access sensitive browser-based information.

Security readout for executives and security teams

Cisco ISE had stored XSS flaws in its web management interface. An unauthenticated remote attacker could place malicious content that runs when an administrator clicks a crafted link or views an affected log page. The likely business risk is compromised admin browser context or exposed browser-held information, not direct system takeover. Exposure is most likely where Cisco Identity Services Engine Software is deployed and its web-based management interface or relevant log views are reachable to users who could be targeted. The provided bundle does not name affected version ranges. Treat as moderate priority, higher if Cisco ISE management access is broadly reachable or administrators routinely review untrusted log content. Because ISE supports identity and network access operations, reduce exposure and confirm vendor remediation rather than deferring indefinitely. Mitigation focus: Review Cisco advisory for affected and fixed ISE releases.; Upgrade Cisco ISE according to vendor guidance.; Restrict management interface access to trusted administrative networks..

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
