A vulnerability classified as critical has been found in VMware open-vm-tools. Affected is some unknown functionality of the file mount.vmhgfs of the component Share Mount Handler. The manipulation with an unknown input leads to a symlink vulnerability. CWE is classifying the issue as CWE-61. The software, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the software to operate on unauthorized files. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:
