Persistent service interruption via out-of-bounds read
Published Aug 13, 2026 · Updated Aug 13, 2026
Out-of-bounds read in Absolute Security Secure Access before 14.57 allows man-in-the-middle attackers to interrupt servers via crafted data. The affected server installer reads beyond a buffer boundary when processing specially crafted data, but Absolute Security has not disclosed the parsing routine or input format. Exploitation requires an in-the-middle network position; the published impact is persistent service interruption without data disclosure or modification.
