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-2026-0803 is a critical SQL injection vulnerability in the PHPGurukul Online Course Registration System up to version 3.1, specifically in the /enroll.php file. The vulnerability occurs because multiple input parameters (studentregno, Pincode, session, department, level, course, and sem) are not properly validated or sanitized before being used in SQL queries. This allows an attacker to inject malicious SQL commands remotely, potentially compromising the system's database. [1, 2]
How can this vulnerability impact me? :
This vulnerability can allow remote attackers to manipulate SQL queries, which may lead to unauthorized access to sensitive data, modification or deletion of data, and potentially full compromise of the underlying database. This can affect the confidentiality, integrity, and availability of the affected system, leading to data breaches or service disruption. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for unusual or malicious SQL injection attempts targeting the /enroll.php endpoint, specifically involving the parameters studentregno, Pincode, session, department, level, course, and sem. One detection method is to use web server logs or intrusion detection systems to look for suspicious input patterns or payloads in POST requests to /enroll.php. Additionally, Google dorking with queries like "inurl:enroll.php" can help identify exposed vulnerable instances. For command-line detection, tools like curl or sqlmap can be used to test the endpoint for SQL injection by sending crafted requests targeting these parameters. Example command using sqlmap: sqlmap -u "http://target/enroll.php" --data "studentregno=1& Pincode=1&session=1&department=1&level=1&course=1&sem=1" --risk=3 --level=5 --batch [1]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing the affected PHPGurukul Online Course Registration System software with a non-vulnerable alternative, as no known countermeasures or patches have been documented. Additionally, restricting access to the /enroll.php endpoint, implementing web application firewalls (WAF) to block SQL injection attempts, and applying input validation and sanitization on all user-supplied parameters can help reduce risk. Since the vulnerability allows remote exploitation, limiting network exposure and monitoring for exploit attempts are also recommended. [1]
