Lifecycle Timeline
7DescriptionCVE.org
A vulnerability was found in code-projects Library System 1.0 and classified as critical. This issue affects some unknown processing of the file /teacher-issue-book.php. The manipulation of the argument idn leads to sql injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.
AnalysisAI
SQL injection in code-projects Library System 1.0 allows remote attackers to manipulate the idn parameter in teacher-issue-book.php, leading to unauthorized database access. An attacker can read, modify, or delete data, potentially compromising the entire application. Public exploit code is available, though active exploitation has not been confirmed.
Technical ContextAI
The vulnerability resides in a PHP-based web application, specifically the 'idn' parameter passed to /teacher-issue-book.php. Lack of input sanitisation (CWE-74) enables SQL injection. The affected product is identified by CPE cpe:2.3:a:code-projects:library_system:1.0:*:*:*:*:*:*:*, a lightweight library management system likely used for educational or small-scale purposes.
RemediationAI
No vendor-released patch has been identified at the time of analysis. As immediate compensating controls, restrict network access to the teacher-issue-book.php endpoint using a firewall or web server configuration. Deploy a web application firewall (WAF) with rules to block SQL injection attempts targeting the idn parameter. If feasible, disable the teacher-issue-book functionality until a code-level fix (parameterized queries) is applied. Note that blocking the endpoint may disrupt intended functionality for librarians or teachers.
