CVE-2019-11454

22
FAUCET Score

CVE-2019-11454 describes a persistent cross-site scripting (XSS) vulnerability in Tildeslash Monit versions prior to 5.25.3, affecting products like Canonical, Debian, FedoraProject, and MMonit. This flaw allows an unauthenticated remote attacker to inject arbitrary JavaScript by manipulating the unsanitized user field within the HTTP Basic Authentication's Authorization header, which is then mishandled during a _viewlog operation. Rated as Medium severity with a CVSS score of 6.1, the attack requires user interaction (UI:R) but can be executed over the network (AV:N) with low complexity (AC:L), potentially leading to limited confidentiality and integrity impacts (C:L/I:L). There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this vulnerability.
