Local unauthorized file access via link following
Published May 5, 2026 · Updated May 5, 2026
Link following in the ASC.exe service in IObit Advanced SystemCare 19 allows local users to access unintended files via crafted links. The public record identifies ASC.exe and the service component but does not disclose the affected file operation, path, link type, or trigger. Exploitation requires low local privileges and high-complexity preparation; successful link redirection lets the service operate on files outside its intended control boundary, affecting their confidentiality, integrity, and availability.
