Description

A vulnerability has been found in mathurvishal CloudClassroom-PHP-Project up to 5dadec098bfbbf3300d60c3494db3fb95b66e7be. This impacts an unknown function of the file updatedetailsfromfaculty.php. Such manipulation of the argument myfid leads to sql injection. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. The vendor was contacted early about this disclosure but did not respond in any way.

  "executiveSummary": "A critical SQL injection vulnerability exists in the mathurvishal CloudClassroom-PHP-Project, specifically impacting the updatedetailsfromfaculty.php script. The vulnerability arises from improper neutralization of user-supplied data within the 'myfid' parameter.\nThis security flaw allows a remote, unauthenticated attacker to manipulate backend database queries, potentially leading to unauthorized data disclosure, modification, or destruction of administrative and user information.\nGiven that the project operates on a rolling release model and the vendor has remained unresponsive, affected systems remain perpetually exposed without official patches.\nThe risk is high, as the vulnerability is publicly disclosed and exploitable remotely, providing attackers with the capability to execute arbitrary SQL commands directly against the underlying database engine.\nOrganizations deploying this project are at risk of complete database compromise if the application service account lacks strict permission segregation.",
  "technicalDetails": "The vulnerability is located in the file updatedetailsfromfaculty.php within the mathurvishal CloudClassroom-PHP-Project. The root cause is the insecure handling of the 'myfid' parameter, which is concatenated directly into a database query without sufficient input sanitization, parameterization, or the use of prepared statements.\nAn attacker can exploit this by injecting malicious SQL syntax into the 'myfid' argument. Because the application fails to validate the structure and content of the input, the malicious payload alters the logic of the intended SQL statement.\nThe attack flow begins when an attacker sends a crafted HTTP request to updatedetailsfromfaculty.php, specifically targeting the 'myfid' query parameter or POST body. The backend PHP script processes this input and passes the unsanitized string into an active database connection.\nBy injecting characters such as single quotes ('), semicolons (;), or SQL comment markers (-- or #), the attacker can terminate the intended query and append unauthorized commands. This allows for techniques such as UNION-based SQL injection to retrieve data from other tables, or Boolean-based/Time-based blind SQL injection to infer data content.\nThe impact is significant, as successful exploitation results in full control over the information stored in the backend database. Depending on the database user's privileges, an attacker could potentially escalate the impact to reading arbitrary files on the filesystem or executing commands on the underlying database server, depending on the specific database engine configuration (e.g., MySQL/MariaDB).\nAffected versions include all iterations of the project up to commit 5dadec098bfbbf3300d60c3494db3fb95b66e7be. As the project follows a continuous delivery model, the lack of versioning and vendor updates necessitates manual code-level intervention to remediate the vulnerability."
