Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Multiple absolute path traversal vulnerabilities in the MW6QRCode.QRCode.1 ActiveX control in MW6QRCode.dll in MW6 Technologies QRCode ActiveX 22.214.171.124 and earlier allow remote attackers to create or overwrite arbitrary files via a full pathname in the argument to the (1) SaveAsBMP or (2) SaveAsWMF method. NOTE: some of these details are obtained from third party information.
CWE-22 - Path Traversal
Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
