Overview<\/strong><\/p>\n

The cybersecurity world is abuzz with the discovery of a new vulnerability in WeiPHP v5.0 and before, tagged as CVE-2025-55849. WeiPHP is a popular open-source framework used by programmers to build applications. However, this vulnerability may allow<\/a> an attacker to manipulate SQL queries, leading to unauthorized access to sensitive data, and potential system compromise. Given the widespread use of WeiPHP, the impact of this vulnerability<\/a> is potentially far-reaching, affecting numerous applications and by extension, organizations and their users.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-55849
\nSeverity: High (CVSS:8.4)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: Unauthorized access to sensitive<\/a> data, potential system compromise<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

WeiPHP | v5.0 and before<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability stems from insufficient sanitization of user-supplied inputs<\/a> in the ‘SucaiController.class.php’ file. An attacker can exploit this by injecting malicious SQL<\/a> code into the application’s query string. This results in the application unknowingly running the malicious SQL query, which can lead to unauthorized access<\/a> to sensitive data, modification of data, or even system compromise.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a conceptual example of how an attacker might exploit the vulnerability. Suppose the application accepts a parameter ‘template_id’ in the URL to fetch some data:<\/p>\n

GET \/SucaiController.class.php?template_id=100 HTTP\/1.1\nHost: vulnerable.example.com<\/code><\/pre>\n
An attacker could substitute ‘100’ with a crafted SQL statement:<\/p>\n
GET \/SucaiController.class.php?template_id=100;DROP%20TABLE%20users; HTTP\/1.1\nHost: vulnerable.example.com<\/code><\/pre>\n
This could lead to the ‘users’ table being dropped from the database<\/a> if the application directly includes the ‘template_id’ parameter in a SQL query without sanitizing it first.<\/p>\n
Mitigation Steps<\/strong><\/p>\n
To mitigate this vulnerability, users are advised to apply the patch provided by the vendor as soon as it’s available. In the interim, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be used to detect and block SQL Injection<\/a> attacks. Additionally, developers should always sanitize user inputs before including them in SQL queries to prevent such injection<\/a> attacks.<\/p>\n","protected":false},"excerpt":{"rendered":"
