Threats affecting pkg:github/meeting-room-booking-system/mrbs-code

MRBS (Meeting Room Booking System) versions before 1.12.3 have a reflected cross-site scripting (XSS) vulnerability in the view_entry.php script via the error parameter.

The Meeting Room Booking System (MRBS) is a PHP-based application for booking meeting rooms. Prior to version 1.12.2, a user-supplied private/local URI can be made to be fetched without checks. Version 1.12.2 contains a fix. No known workarounds are available.

The Meeting Room Booking System (MRBS) is a PHP-based application for booking meeting rooms. Prior to version 1.12.2, an unauthenticated request can be made to redirect the user to a query-specified location. This allows an attacker to create a specially-crafted URL to an MRBS installation that will cause the user who clicks it to be redirected to the attacker-specified redirect URL, which could be a spoofed MRBS login page, for example. Version 1.12.2 contains a fix. No known workarounds are available.
