Title: Extropia WebStore Directory Traversal Vulnerability

Severity: MODERATE

Description:

Extropia WebStore is an e-commerce shopping cart application consisting of routines for error handling, order processing, encrypted mailing, frames, Javascript and VBscript.

The routine web_store.cgi does not properly handle the $file_extension variable if null characters are used.

For example if the following URL was requested, the file in question would not be delivered to the user:

http://target/cgi-bin/Web_Store/web_store.cgi?page=../../../path/filename.ext

However, by using the escaped character "%00", the requested file would be accessed successfully:

http://target/cgi-bin/Web_Store/web_store.cgi?page=../../../path/filename%00ext

Successful exploitation could lead to a remote intruder gaining read access to any known file.

Affected Products:

  • Extropia WebStore 1.0.0
  • Extropia WebStore 2.0.0
