EUVDB-ID: #VU21248

Risk: High

CVSSv3.1: 8.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N/E:P/RL:U/RC:C]

CVE-ID: CVE-2019-16642

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists in the App\Mobile\Controller\ZhuantiController.class.php file due to insufficient sanitization of user-supplied data passed via the id parameter to index.php/Mobile/Zhuanti/group URL. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.

3) Cross-site scripting

EUVDB-ID: #VU21264

Risk: Low

CVSSv3.1: 5.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:U/RC:C]

CVE-ID: CVE-2019-16657

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data passed to the "index.php/article/group/id/2/" when processing the PATH_INFO to a group URI. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Example:

http://[host]/index.php/article/group/id/2/%f6%22%20onmouseover%3dprompt("XSS")%20///1.html

 

Mitigation

Install update from vendor's website.
