FAUCET Score

CVE-2018-0396 is a cross-site scripting (XSS) vulnerability in the web framework of Cisco Unified Communications Manager IM and Presence Service software, stemming from insufficient input validation. An authenticated, remote attacker could exploit this by tricking a user into clicking a malicious link or by injecting malicious code into a user's request. Successful exploitation could lead to arbitrary script execution in the user's browser or access to sensitive browser-based information. Rated as Medium severity with a CVSS score of 6.1, this vulnerability requires user interaction (UI:R) and has low impact on confidentiality and integrity (C:L, I:L). The attack complexity is low (AC:L), and it can be exploited over the network (AV:N). Currently, there is no evidence of active exploitation, and no public exploit code is available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, consistent with a large percentage of reported vulnerabilities.
