Description

A security flaw has been discovered in mathurvishal CloudClassroom-PHP-Project up to 5dadec098bfbbf3300d60c3494db3fb95b66e7be. The impacted element is an unknown function of the file /updateguest.php. Performing a manipulation of the argument gname/editassid results in sql injection. It is possible to initiate the attack remotely. The exploit has been released to the public and may be used for attacks. This product is using a rolling release to provide continious delivery. Therefore, no version details for affected nor updated releases are available. 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, affecting versions up to 5dadec098bfbbf3300d60c3494db3fb95b66e7be.\nThe vulnerability resides within the /updateguest.php file, where improper neutralization of special elements used in SQL commands occurs.\nSuccessful exploitation allows remote, unauthenticated attackers to manipulate database queries by injecting malicious SQL statements through the 'gname' or 'editassid' parameters.\nThis flaw facilitates unauthorized access to sensitive backend data, modification of database content, and potentially administrative bypass.\nGiven that exploit code is publicly available and the vendor has remained unresponsive, the risk to deployments is considered high.\nThere are no specific versioned patches available due to the project's rolling release nature; therefore, immediate manual intervention is required to secure affected instances.",
  "technicalDetails": "The vulnerability is a classic SQL injection flaw stemming from inadequate input sanitization in the /updateguest.php file of the mathurvishal CloudClassroom-PHP-Project.\nThe root cause is the direct inclusion of user-supplied input from the 'gname' or 'editassid' HTTP parameters into dynamic SQL query strings without prior validation or the use of parameterized queries (prepared statements).\nAn attacker can exploit this by crafting malicious input containing SQL syntax, which alters the structure of the intended database query executed by the application.\nThe attack flow begins when an attacker sends a crafted HTTP request (GET or POST) to /updateguest.php, embedding the injection payload within the 'gname' or 'editassid' arguments.\nBecause the input is not escaped or bound, the database engine interprets the attacker's payload as a valid SQL command, effectively breaking out of the intended query context.\nThis behavior permits a wide range of adversarial operations, including 'UNION-based' SQL injection to extract data from other tables, 'Boolean-based' inference to enumerate database contents, or 'Error-based' techniques to disclose database schema information.\nThe vulnerability is remotely exploitable without requiring authentication, exposing the backend database to full compromise.\nPost-exploitation impact includes unauthorized data exfiltration, deletion of records, bypassing of application-level authentication, and in misconfigured environments, potentially remote code execution via database features like INTO OUTFILE.\nSince the product utilizes a rolling release model, the vulnerability persists until the source code is manually updated or hardened by the system administrator, as no official version-stamped patch exists."
