DescriptionCVE.org

ICEcoder versions through 8.1 fail to properly validate the oldFileName parameter in file move and rename operations, allowing authenticated users to relocate files from outside the document root. Attackers can use path traversal sequences in oldFileName to move files writable by the PHP process into the web-accessible project directory, disclosing file contents and deleting originals.

AnalysisAI

Path traversal in ICEcoder through version 8.1 enables authenticated low-privilege users to move arbitrary files from outside the web document root into web-accessible directories by injecting traversal sequences into the oldFileName parameter of rename and move operations. The flaw, located in lib/file-control.php around line 198, allows an attacker to expose sensitive server-side file contents via direct HTTP retrieval while simultaneously deleting the original - combining information disclosure with destructive write impact. …
