Local privilege change via unchecked stack buffer write
Published Dec 13, 2021 · Updated Sep 17, 2024
Stack-based buffer overflow in IBM i2 Analyst's Notebook 9.2.0 through 9.2.2 allows local users to gain lower-level privileges. IBM attributes the overwrite to improper bounds checking but does not identify the affected component, input format, or buffer operation. Exploitation requires local access and user interaction; the reported consequence is reduced privilege rather than code execution or full administrative control.
