Vulnerable component: nBill
CVE-ID: CVE-2010-4270
CVSSv3 score: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N/E:F/RL:O/RC:C
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Description:
The vulnerability allows a remote attacker to view contents of arbitrary files on the server.
The vulnerability exists due to insufficient filtration of user-supplied input in "/administrator/components/com_nbill/admin.nbill.php" and "/components/com_nbill/nbill.php" scripts. A remote attacker can send specially crafted HTTP request, containing directory traversal sequences (e.g. тАЬ../тАЭ) and view contents of arbitrary file on vulnerable server.
Successful exploitation of the vulnerability may allow an attacker to gain unauthorized access to potentially sensitive information.
Note: this vulnerability is being actively exploited against Joomla! installations.
