RTIR's ticket split and incident creation forms display the subject of the related ticket without HTML escaping. A script placed in that subject runs in the session of the handler who opens the form, so it can act in RT with that user's authority.

Teams running RTIR (Request Tracker for Incident Response) where anyone can submit an emailed report, since RTIR grants everyone the right to create Incident Reports by default. Exposure comes from the split and incident creation forms that display a related ticket's subject; RTIR 5.0 is not affected and deployments that restrict Incident Report creation to authenticated users reduce the risk.

rtir --version or the RTIR package metadata in your RT installation.6.0.4.Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
RTIR's ticket creation forms show the subject of the related ticket when splitting a ticket or creating an incident from a report, and they render that subject without HTML escaping. A ticket subject containing script runs it when a user opens either form. RTIR grants everyone the right to create Incident Reports by default, so an unauthenticated sender of an emailed report can set that subject. The script then runs in the session of the incident handler who creates an incident from the report or splits it, and can act in RT with that user's authority.
The issue was fixed in version 6.0.4. RTIR 5.0 is not affected.
