This vulnerability involves an SQL injection flaw in CodeAstro Online Classroom 1.0, specifically in the /updatedetailsfromstudent.php script when processing the 'fname' argument. An attacker can remotely manipulate this parameter to inject SQL commands, potentially compromising the database. The CVSS 4.0 base score is 5.3 (medium), reflecting network attack vector, low complexity, no privileges required, and no user interaction needed. The vulnerability has been publicly disclosed but lacks an official fix or vendor advisory at this time.

Successful exploitation could allow an attacker to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data access or modification. The impact is limited by the low scope and low confidentiality, integrity, and availability requirements as indicated by the CVSS vector. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, it is recommended to apply input validation and parameterized queries as a temporary mitigation if possible.
