Detailsinfo

A vulnerability was found in 1E Client on Windows (the affected version is unknown) and classified as critical. This issue affects an unknown code. The manipulation with an unknown input leads to a link following vulnerability. Using CWE to declare the problem leads to CWE-59. The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

1E Client installer can perform arbitrary file deletion on protected files.   A non-privileged user could provide a symbolic link or Windows junction to point to a protected directory in the installer that the 1E Client would then clear on service startup. A hotfix is available Q23092 that forces the 1E Client to check for a symbolic link or junction and if it finds one refuses to use that path and instead creates a path involving a random GUID.
