——29React Router is a router for React. In @react-router/node versions 7.0.0 through 7.9.3, @remix-run/deno prior to version 2.17.2, and @remix-run/node prior to version 2.17.2, if createFileSessionStorage() is being used from @react-router/node (or @remix-run/node/@remix-run/deno in Remix v2) with an unsigned cookie, it is possible for an attacker to cause the session to try to read/write from a location outside the specified session file directory. The success of the attack would depend on the permissions of the web server process to access those files. Read files cannot be returned directly to the attacker. Session file reads would only succeed if the file matched the expected session file format. If the file matched the session file format, the data would be populated into the server side session but not directly returned to the attacker unless the application logic returned specific session information. This issue has been patched in @react-router/node version 7.9.4, @remix-run/deno version 2.17.2, and @remix-run/node version 2.17.2.2d CVE-2024-488847.5 HIG

——29In pfSense CE /suricata/suricata_ip_reputation.php, the value of the iplist parameter is not sanitized of directory traversal-related strings/characters. This value is directly used in a file existence check operation. While the contents of the file cannot be read, the server reveals whether the file exists, which enables an attacker to enumerate files on the target. The attacker must be authenticated with at least "WebCfg - Services: suricata package" permissions.2d CVE-2022-233477.5 HIG
