Exploit Details

The CVE-2023-46196 vulnerability stems from a lack of proper authorization checks, which allows an attacker to access restricted areas and gain unauthorized control over user data. The exploit takes advantage of incorrectly configured access control security levels, leading to unauthorized access and potential data manipulation.

The primary component of the vulnerability lies within the following code snippet

function getData(id) {
  // Missing authorization check
  const userData = database.getUserData(id);
  return userData;
}

As illustrated in the snippet above, the vulnerable function getData(id) retrieves user data from a database without performing any authorization check. This allows an attacker to access and potentially alter the data, which can lead to unwanted actions such as stealing customer information and impacting the overall integrity and credibility of the Repuso software.

Vendors and third-party developers utilizing the Repuso Social Proof Testimonials and Reviews library should also apply these recommendations and introduce appropriate security measures within their offerings to avoid exposing their customers to potential threats.

Stay vigilant, act responsibly, and upgrade your software to ensure the security of your data and the trust of your customers.
