Title
Cross-Site Request Forgery in the Administrative User Deletion Endpoint
Summary
CTI-Transmute contained a cross-site request forgery vulnerability in the administrative user deletion functionality. The /account/delete/<id> endpoint accepted HTTP GET requests for an operation that modified application state. An unauthenticated remote attacker could construct a malicious link or embed a request targeting this endpoint and induce an authenticated CTI-Transmute administrator to visit the attacker-controlled content. If the administrator had an active session, the browser would automatically include the administrator’s session credentials, causing the selected user account to be deleted without the administrator intentionally confirming the operation. Successful exploitation requires interaction from a currently authenticated administrator who has permission to delete users. The attacker does not need a CTI-Transmute account or administrative privileges because the forged request executes using the victim administrator’s session. The vulnerability could allow an attacker to delete arbitrary user accounts, resulting in unauthorized modification of application state and denial of access for affected users. Depending on whether administrators can delete other administrators or the final administrative account, exploitation could also disrupt administration of the CTI-Transmute instance. The patch resolves the issue by restricting the deletion endpoint to HTTP POST requests and submitting the deletion through a form containing a CSRF token.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
