A recent vulnerability discovered in the AtomChat application stands to compromise the integrity of the platform. The issue lies in the Missing Authorization vulnerability, which exposes the system to breaches that may impact a wide range of users.

This long read post will uncover the details of the CVE-2023-46606 vulnerability, providing code snippets, links to original references, and insights into the exploit. By the end, readers will have an exclusive understanding of this threat in simple, American English.

Affected Versions

The vulnerability affects AtomChat versions from n/a to 1.1.4.

Exploit Details

This specific vulnerability identified as CVE-2023-46606 impacts AtomChat owing to the presence of an incorrectly configured access control security level. An attacker can exploit this vulnerability to gain unauthorized privileges and access, enabling the breach of sensitive user information within the platform.

The Incorrectly Configured Access Control Security Level vulnerability occurs due to insufficient verification of user authorization. As a result, an attacker with minimal understanding of the platform can exploit this issue and bypass the security level controls in place.

Code Snippet

To illustrate the vulnerability in AtomChat's code, let's look at an example of how the Missing Authorization vulnerability might manifest:

def sendMessage(User, Message):
	verifyUser(User, AccessLevel)
	ADD_MESSAGE_TO_CHAT(Message)

In the code snippet above, the verifyUser function is supposed to confirm the user's authorization level. However, the lack of proper access level verification makes it possible to bypass the process:

def verifyUser(User, AccessLevel):
	if AccessLevel < REQUIRED_LEVEL:
		raise 'Invalid access'

The above code demonstrates the insufficient verification of user authorization in the software.

So, a potential attacker can inject malicious code based on this flaw to gain unauthorized access to the platform.
