CVE-2023-35159

27
FAUCET Score

CVE-2023-35159 is a Cross-Site Scripting (XSS) vulnerability affecting XWiki Platform versions 3.4-milestone-1 up to 14.10.4 and 15.0. It allows an unauthenticated attacker to inject malicious JavaScript into a user's browser by crafting a specific URL, specifically leveraging the 'deletespace' template. Rated Medium severity (CVSS 6.1), it requires user interaction (UI:R) but has low attack complexity (AC:L), potentially leading to information disclosure (C:L) and integrity compromise (I:L). While not actively exploited (KEV: No) and lacking public Metasploit or ExploitDB modules, a Nuclei template exists, and it has received minimal community discussion or media coverage.
