Overview
CVE-2025-13203 describes a critical SQL injection vulnerability found in Simple Cafe Ordering System version 1.0. This vulnerability allows a remote attacker to execute arbitrary SQL commands on the application’s database, potentially leading to data breaches, unauthorized access, or complete system compromise. The vulnerability resides in the /addmem.php file and is exploitable via manipulation of the studentnum argument.
Technical Details
The vulnerability stems from improper sanitization of user-supplied input within the /addmem.php script. Specifically, the studentnum parameter is not adequately validated before being used in an SQL query. This allows an attacker to inject malicious SQL code into the query, which is then executed by the database server. The publicly available exploit demonstrates how a crafted payload injected into the studentnum parameter can bypass existing security measures (if any) and directly manipulate the database.
CVSS Analysis
- CVSS Score: 7.3 (HIGH)
- This score reflects the high potential impact and ease of exploitation. A remote attacker can exploit this vulnerability without requiring authentication.
Possible Impact
Successful exploitation of CVE-2025-13203 can have severe consequences:
- Data Breach: Attackers can access sensitive data, including user credentials, order history, and financial information.
- Unauthorized Access: Attackers can gain unauthorized access to administrative functionalities, allowing them to modify application settings, create new accounts, or escalate privileges.
- Data Manipulation: Attackers can modify or delete data within the database, leading to data corruption and system instability.
- System Compromise: In severe cases, attackers may be able to gain complete control over the underlying server, leading to a full system compromise.
Mitigation or Patch Steps
To mitigate the risk posed by CVE-2025-13203, the following steps are recommended:
- Input Validation: Implement robust input validation and sanitization for all user-supplied data, especially the
studentnumparameter in/addmem.php. Use parameterized queries or prepared statements to prevent SQL injection attacks. - Web Application Firewall (WAF): Deploy a WAF to detect and block malicious requests targeting the SQL injection vulnerability.
- Update/Patch: Check for any available patches or updates from the vendor (code-projects.org). If a patch is available, apply it immediately. If no patch is available, consider discontinuing use of the software until a secure version is released.
- Database Permissions: Follow the principle of least privilege. Ensure the database user used by the application has only the necessary permissions to perform its functions. Avoid granting the database user administrative privileges.
