Unauthorized hardware configuration changes via improper escaping
Published Jun 11, 2021 · Updated Aug 3, 2024
Improper output encoding in Gallagher Command Centre Server allows remote authenticated users to alter hardware configuration beyond their privileges. Gallagher has not disclosed which server code path mishandles operator-controlled input or which output lacks required encoding. Access as a Command Centre Operator is required, and exploitation permits unauthorized changes to Controllers and other hardware items.
