Technical details

An incorrect authorization flaw (CWE-863) in Adobe ColdFusion permits authenticated users to perform arbitrary file system write operations beyond their intended permissions. Attack vector is network-based with low attack complexity; an authenticated attacker can exploit this without user interaction. The impact is limited to integrity (arbitrary write) without confidentiality or availability loss, though file write capabilities often lead to code execution in web contexts.
