CVE-2018-15455

21
FAUCET Score

CVE-2018-15455 describes a cross-site scripting (XSS) vulnerability in the logging component of Cisco Identity Services Engine (ISE). This flaw allows an unauthenticated, remote attacker to inject malicious scripts into the system's logging database by sending specially crafted requests. When an administrator views these logs in the Admin Portal, the scripts execute, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS score of 6.1 (Medium) due to its network-based attack vector and low attack complexity, but requires user interaction (viewing logs) for exploitation. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
