Vulnerability Title
LimeSurvey RemoteControl invite_participants/remind_participants SQL Injection
Vulnerability Description
The RemoteControl API methods invite_participants and remind_participants pass a caller-supplied token-ID array into TokenDynamic::findUninvited(), which concatenates the values directly into a tid IN ('...') SQL clause without parameterization or input validation. A remote, authenticated attacker holding the tokens/update permission on a survey can inject a crafted array element to perform SQL injection. Because LimeSurvey configures its PDO connection with emulated prepared statements (emulatePrepare = true) and does not disable MySQL multi-statements, the injection supports stacked queries: the attacker can append arbitrary additional statements (INSERT/UPDATE/DELETE/DROP/CREATE) after the original SELECT. This permits both arbitrary read of any data in the database, such as administrator bcrypt password hashes (lime_users), survey response PII, session records, and global settings, all recoverable via a SLEEP() time-based blind oracle, and arbitrary write/destruction of that data, including directly overwriting the administrator password hash for immediate account takeover or dropping/truncating tables. Reads and writes extend to any schema the application's database user can access. The RemoteControl interface (RPCInterface = json/xml) must be enabled, which is not the default.

Vulnerability Title
LimeSurvey SQL注入漏洞
Vulnerability Description
LimeSurvey(PHPSurveyor)是LimeSurvey团队的一套开源的在线问卷调查程序,它支持调查程序开发、调查问卷发布以及数据收集等功能。 LimeSurvey存在SQL注入漏洞,该漏洞源于RemoteControl API方法将调用者提供的令牌ID数组直接拼接进SQL子句而未参数化或输入验证,可能导致远程认证攻击者执行SQL注入,实现任意数据读写和账户接管。以下版本受到影响:RemoteControl接口启用时。
