Technical details

An Improper Input Validation vulnerability (CWE-20) exists in Adobe Dreamweaver Desktop versions 21.7 and earlier. The flaw allows for an arbitrary file system read when the application fails to properly validate input from a file opened by the user. An attacker can exploit this by crafting a malicious file that, when opened, leverages the changed scope (S:C) to access sensitive information outside of the application's intended directory constraints. This is a local attack vector requiring user interaction (UI:R) but no prior privileges (PR:N). Adobe has addressed this in security bulletin APSB26-62.
