VUL-0: CVE-2023-45539: haproxy: misinterpretation of a path_end rule with # as part of the URI component
Last modified: 2024-07-09 20:30:50 UTC
HAProxy before 2.8.2 accepts # as part of the URI component, which might allow remote attackers to obtain sensitive information or have unspecified other impact upon misinterpretation of a path_end rule, such as routing index.html#.png to a static server.
