Memory disclosure via Hostmessage format-string injection
Published Sep 9, 2022 · Updated Sep 17, 2024
Format-string injection in Baxter Spectrum WBM 16, 16D38, 17, 17D19, and 20D29 through 20D32 allows remote authenticated users to read memory. The Telnet Hostmessage command treats attacker-supplied text as a format string, exposing stack values when trace output is enabled. Exploitation requires a superuser Telnet session; viewing the leaked output additionally requires settrace state=on, and the reported consequence is confined to information disclosure.
