Exploitability
| CWE ID | Description |
|---|---|
| CWE-74 | The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. |
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-0733 is a SQL injection vulnerability in the PHPGurukul Online Course Registration System up to version 3.1. It occurs due to improper handling and lack of input sanitization of the 'cid' parameter in files such as /onlinecourse/admin/manage-students.php and /onlinecourse/check_availability.php. This allows an attacker to manipulate SQL queries remotely without authentication, potentially injecting malicious SQL commands to access or modify the database. [1, 2, 3]
How can this vulnerability impact me? :
This vulnerability can allow attackers to remotely execute arbitrary SQL commands on the backend database, leading to unauthorized access to sensitive information such as admin passwords, modification or deletion of data, and disruption of service. It compromises the confidentiality, integrity, and availability of the system, potentially resulting in data breaches and operational impact. [1, 2, 3]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by testing the vulnerable parameter `cid` in the affected PHP files for SQL injection. Automated tools like sqlmap can be used to detect exploitation by sending crafted requests to the endpoint. For example, the following sqlmap command can be used to test the `/check_availability.php` endpoint: sqlmap -u "http://<target-ip>/check_availability.php" --data="cid=1" --cookie="PHPSESSID=xxx" --dbs. Additionally, attackers can be identified by searching for URLs containing `onlinecourse/admin/manage-students.php` using Google dorking with the query: inurl:onlinecourse/admin/manage-students.php. [2, 3]
What immediate steps should I take to mitigate this vulnerability?
No known mitigations or countermeasures have been published for this vulnerability. It is suggested to replace the affected component with an alternative product. Immediate steps include restricting access to the vulnerable endpoints, monitoring for suspicious activity, and applying any available patches or updates from the vendor once released. [3]
