According to its self-reported version, the instance of Dotnetnuke running on the remote web server is prior to 10.3.3.It is, therefore, affected by a vulnerability.
- An authorization vulnerability in the Image Processor could allow an unauthenticated user to access image files that were intended to be protected by DNN's file and folder permissions. Sites using restricted or secure file storage should upgrade to a patched release to ensure image processing operations consistently enforce configured access controls. A vulnerability was identified in the Image Processor where authorization checks were not consistently enforced before processing protected image files. Under certain conditions, an unauthenticated user could retrieve images stored in locations intended to restrict anonymous access. Successful exploitation could disclose sensitive images that administrators expected to remain protected by DNN's file authorization model. Depending on how the platform is used, affected images could include user-uploaded media, scanned documents, screenshots, branding assets, or other confidential visual content. (GHSA-g8w5-h3rm-g8rj)
