Description
This security bulletin contains information about 1 vulnerability.
1) Directory traversal (CVE-ID: N/A)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:A/U:Amber
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target sustem.
The weakness exists due to improper filtration of user-supplied input passed via the "file" HTTP GET parameter to "/magmi-importer/web/download_file.php" script. A remote attacker can use directory traversal sequences (e.g. "../../") to view contents of arbitrary files on the target system.
Exploitation example observed in the wild:
GET /…sanitized…/magmi-importer/web/download_file.php?file=../../app/etc/local.xml HTTP/1.1Successful exploitation of the vulnerability results in disclosure of confidential and sensitive information from the root folder of the application. In case of Magento, the "/app/etc/local.xml" file contains credentials and encryption keys.
Note: the vulnerability was being actively exploited.
Remediation
