Spreadsheet data disclosure via unneutralized log fields
Published Mar 30, 2022 · Updated Aug 3, 2024
CSV injection in RuoYi 4.7.2 allows remote attackers to expose spreadsheet data when an administrator opens an exported login log. The ruoyi-admin login-log export writes an attacker-controlled username beginning with a formula marker into an .xlsx cell without neutralization. The attacker submits the username without authentication, but disclosure requires a log administrator to open and activate the HYPERLINK formula, which sends referenced cell contents to an attacker-controlled HTTP endpoint.
