IBM Spectrum Protect 7.1 and 8.1 could allow a local attacker to launch a symlink attack. IBM Spectrum Protect Backup-archive Client creates temporary files insecurely. A local attacker could exploit this vulnerability by creating a symbolic link from a temporary file to various files on the system, which could allow the attacker to overwrite arbitrary files on the system with elevated privileges. IBM X-Force ID: 125163.
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.
