Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability was determined in CodeAstro Online Classroom 1.0. This issue affects some unknown processing of the file /OnlineClassroom/updatedetailsfromfaculty.php?myfid=108 of the component Parameter Handler. Executing a manipulation of the argument fname can lead to sql injection. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

CodeAstro Online Classroom 1.0 contains a SQL injection vulnerability in the updatedetailsfromfaculty.php script via the fname parameter. An attacker can manipulate this parameter to inject arbitrary SQL queries, potentially allowing unauthorized database access, data exfiltration, or data modification. The vulnerability is remotely exploitable and a public exploit exists.

MitigationReplace dynamic SQL queries with parameterized queries/prepared statements to neutralize SQL injection vectors. Additionally, implement strict input validation on all user-supplied parameters and consider deploying a WAF as a defense-in-depth measure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm CodeAstro Online Classroom installation
    Locate the application root directory and verify the presence of the OnlineClassroom folder structure, particularly the updatedetailsfromfaculty.php file.
    Affected if The application and vulnerable PHP file are present on the server.
  2. Identify installed version
    Check for version indicators such as a version file, footer in the application, or any version metadata within the application source code.
    Affected if The installed version is CodeAstro Online Classroom 1.0.
  3. Examine the fname parameter handler
    Open /OnlineClassroom/updatedetailsfromfaculty.php and locate the code that processes the fname parameter. Search for SQL query construction involving this parameter.
    Affected if The code directly incorporates the fname parameter into an SQL query without using prepared statements or parameter binding.
  4. Inspect database query implementation
    Review the database query logic around the updatedetailsfromfaculty.php file. Look for mysql_query, mysqli_query, or PDO query calls that include the fname variable in the query string.
    Affected if SQL queries are built dynamically with user input without parameterized queries.

You are affected if CodeAstro Online Classroom 1.0 is installed and the updatedetailsfromfaculty.php file contains direct incorporation of the fname parameter into SQL queries without prepared statements.
