Joomla Extension - j2commerce.com - Arbitrary file read via task=download in J2Store 1.0.0-3.3.2, 4.0.0-4.0.22, 4.1.0-4.1.7 - J2StoreModelOrderdownloads::getFilePath() built the on-disk path to a purchased digital download by concatenating the configured attachment folder with the product file's stored product_file_save_name, using only JPath::clean() (which normalises separators but does not resolve or reject .. segments) and a plain JFile::exists() check - never confirming the resolved path stayed inside the configured attachment folder. If a product file's product_file_save_name ever contained a ../ traversal segment - most plausibly via the CSRF-forgeable admin product-file save actions described in Issue 1, but equally by any future integration or bug that writes that field - any customer holding a valid download token/pid pair for that product file could have the traversal resolve to a path outside the attachment folder and download any file readable by the web server (e.g. configuration.php).
AnalysisAI
An arbitrary file read flaw in the J2Store e-commerce extension for Joomla (versions 1.0.0–3.3.2, 4.0.0–4.0.22 and 4.1.0–4.1.7) lets anyone holding a valid download token/pid pair for a product download retrieve files outside the configured attachment folder. The J2StoreModelOrderdownloads::getFilePath() routine builds the on-disk path by concatenating the attachments directory with the stored product_file_save_name and only runs JPath::clean() plus JFile::exists(), so a ../ segment in that stored value resolves outside the folder and exposes files such as configuration.php to the web server's read permissions. …
