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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":38,"depthScoreParts":{"impact":38,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
