Uncovering the CVE-2022-32282 Vulnerability in WWBN AVideo 11.6 Login Functionality: Bypassing Password Checks with Existing Hashes

Cybersecurity researchers have discovered a new security vulnerability classified as CVE-2022-32282 in the well-known WWBN AVideo streaming platform version 11.6 and dev master commit 3f7c0364. This vulnerability, caused by an improper password check during the login process, can allow attackers armed with users' password hashes to gain access to users' accounts, thus granting them increased privileges and possibly enabling a wide range of malicious activities targeting your sensitive data.

In this article, we delve into the technical details surrounding CVE-2022-32282 to help you better understand its implications, explore potential exploit examples, and provide guidance on how to protect your AVideo installations against this critical vulnerability. Links to the original references and additional resources have also been provided to facilitate further investigation.

Background and Vulnerability Discovery

WWBN AVideo is an open-source video streaming platform available on GitHub (https://github.com/WWBN/AVideo). Recently, the login function of AVideo version 11.6 and dev master commit 3f7c0364 was found to contain a crucial security vulnerability classified as CVE-2022-32282.

The problem stems from a flawed password check in AVideo's login functionality. More precisely, an attacker who possesses a user's password hash may bypass the standard password checking mechanism and directly log in to the user's account, subsequently acquiring increased privileges.

Here's a code snippet from the vulnerable login function for a better understanding

// Sample code illustrating the improper password check
function loginUser() {
  $passwordHash = $_POST['passwordHash'];
  $storedHash = getUserPasswordHashFromDatabase();
  
  if ($passwordHash == $storedHash) {
    // Login successful
  } else {
    // Login failed
  }
}

Exploit Details

CVE-2022-32282 can be exploited by attackers equipped with users' password hashes, which might have been obtained through various malicious means such as database leaks, phishing attacks, or previously compromised systems.

By skipping the standard password verification process and directly comparing the input password hash with the stored hash in the system, the attackers can effectively bypass password protections in AVideo and acquire unauthorized access to users' accounts.

The security implications of this vulnerability are significant, as attackers with elevated privileges can manipulate user data, impersonate legitimate users, distribute malicious content through the streaming platform, or even exploit other security flaws in the system.
