Authenticated data disclosure via stack buffer overflow
Published May 23, 2022 · Updated Aug 3, 2024
Stack-based buffer overflow in Xlight FTP 3.9.3.2 allows remote authenticated users to disclose sensitive information via crafted input. Public materials show that an oversized payload overwrites structured exception handling and uses an egghunter with return-oriented programming, but they do not identify the receiving command or field. A network-authenticated account is required, and the published record limits the claimed data impact to disclosure rather than modification.
