CVE-2017-12307

17
FAUCET Score

CVE-2017-12307 describes a reflected cross-site scripting (XSS) vulnerability in the web framework of Cisco Small Business Managed Switches, including the 300 and 500 Series, 350, 350X, 550X, and ESW2 Series. This flaw stems from insufficient input validation, allowing an unauthenticated, remote attacker to execute arbitrary script code in a user's browser context by convincing them to click a malicious link. Rated Medium severity (CVSS 6.1), the attack requires user interaction but has low attack complexity, potentially leading to limited data compromise and integrity impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage for this vulnerability.
