CVE-2021-28128 is a high-severity vulnerability affecting Strapi versions up to 3.6.0. This vulnerability allows an attacker who has access to a valid session to change their own password without needing to enter the current password. This weakness can lead to account takeover, making it critical for organizations using Strapi to address this issue promptly.
With a CVSS score of 8.1, this vulnerability is classified as high severity due to its potential impact on confidentiality and integrity. Attackers may leverage this flaw to gain unauthorized access to user accounts, posing a significant risk to organizations. Therefore, organizations should prioritize patching immediately.
As of the latest updates, there are no known exploits or proofs of concept available for this vulnerability. However, the attack vector is network-based, and it requires low privileges to exploit, indicating a relatively straightforward path for attackers to take advantage of this flaw.
Organizations using Strapi should assess their systems to ensure they are running the latest version. This vulnerability underscores the importance of maintaining secure configurations and monitoring for any anomalous behavior that may indicate attempted exploitation.
Vulnerability Details
The official description of this vulnerability states: 'In Strapi through 3.6.0, the admin panel allows the changing of one's own password without entering the current password. An attacker who gains access to a valid session can use this to take over an account by changing the password.' This vulnerability is classified under CWE-640, which pertains to the failure to enforce password change requirements.
The CVSS score is 8.1, indicating high severity, with the following metrics: attack vector (network), attack complexity (low), privileges required (low), user interaction (none), confidentiality impact (high), integrity impact (high), and availability impact (none).
The affected product is Strapi, specifically versions up to 3.6.0. The vulnerability was published on May 6, 2021, and remains a concern for users of the platform.
Technical Analysis
The root cause of this vulnerability lies in the inadequate enforcement of password change policies within the Strapi admin panel. Attackers who gain access to a valid session can exploit this flaw to change their password without the need for the current password, effectively taking control of the account.
The attack vector is network-based, meaning that the attacker does not need to be physically present on the local network to exploit this vulnerability. The attack complexity is classified as low, indicating that the exploit can be executed with minimal technical skill. Privileges required to exploit the vulnerability are low, as the attacker only needs to have a valid session, while user interaction is not required.
The impact on confidentiality and integrity is high, as attackers may gain unauthorized access to sensitive user information, potentially leading to further breaches or malicious activities. However, there is no impact on availability.
Risk & Impact Analysis
The risk to organizations includes potential account takeovers and unauthorized access to sensitive data. Given the nature of the vulnerability, it can be particularly damaging in environments where Strapi is used to manage critical user data or applications. The blast radius is significant, as any compromised account could lead to further exploitation of the platform.
Organizations should assess the urgency based on the CVSS score of 8.1, indicating a high level of risk. This vulnerability is especially pertinent for organizations that rely heavily on Strapi for their applications and services, as the potential for exploitation is real and could lead to severe consequences.
