Unauthenticated database disclosure via DELETE_STR concatenation
Published Nov 9, 2023 · Updated Nov 21, 2024
SQL injection in Tongda OA 2017 11.0 through 11.9 allows attackers to read database contents via a crafted DELETE_STR value. The handler in general/system/censor_words/module/delete.php directly splices DELETE_STR into an SQL statement, letting supplied parentheses and clauses alter the query. No authentication or user interaction is required; the published proof of concept demonstrates blind, timing-based extraction of database information.
