Description

Dell SupportAssist for Home PCs versions 4.6.1 and prior and Dell SupportAssist for Business PCs versions 4.5.0 and prior, contain a symbolic link (symlink) attack vulnerability in the software remediation component. A low-privileged authenticated user could potentially exploit this vulnerability, gaining privileges escalation, leading to arbitrary deletion of files and folders from the system.

• CWE-61UNIX Symbolic Link (Symlink) FollowingThe product, 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 product to operate on unauthorized files.
• CWE-59Improper Link Resolution Before File Access ('Link Following')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.
