Command execution via unfiltered route password
Published Jun 13, 2025 · Updated Jun 13, 2025
Command injection in nine B-LINK router firmware builds allows remote attackers to execute operating-system commands through routepwd. The /bin/goahead sub_45B238 function uses sprintf to place the unfiltered value in a command that bl_do_system executes. The published request supplies an administrative cookie, but the report does not establish whether a valid session is required; commands run with the web service's privileges.
