This article provides detailed information about CVE-2023-47107, a vulnerability in PILOS that allows for account takeover through password reset poisoning.
Understanding CVE-2023-47107
This vulnerability, assigned by GitHub_M, affects PILOS, an open-source front-end for BigBlueButton servers with a built-in load balancer. By manipulating the password reset URL, attackers can potentially disclose the password reset token.
What is CVE-2023-47107?
CVE-2023-47107 allows threat actors to manipulate the password reset URL in PILOS. When victims follow the link, it may lead to the attacker's server, exposing the reset token. The issue impacts local user accounts.
The Impact of CVE-2023-47107
With a CVSS v3.1 base score of 8.8, this vulnerability has a high impact on confidentiality, integrity, and availability. Successful exploitation can lead to unauthorized access to user accounts.
Technical Details of CVE-2023-47107
The vulnerability arises from the password reset component in PILOS, where the reset URL is constructed using the host header supplied in the request. The issue affects PILOS versions greater than or equal to 2.0.0 and less than 2.3.0.
Vulnerability Description
The flaw enables attackers to craft malicious URLs that, if followed by users with the reset option enabled, can redirect to a server controlled by the attacker, thereby revealing the password reset token.
Affected Systems and Versions
PILOS versions from 2.0.0 to 2.3.0 are vulnerable to this account takeover issue through password reset poisoning.
Exploitation Mechanism
By manipulating the reset URL, threat actors can trick users into generating password reset tokens that lead to the attacker's server, compromising the security of PILOS accounts.
Mitigation and Prevention
To protect your systems from CVE-2023-47107, consider the following steps:
Immediate Steps to Take
- Disable the password reset option in affected PILOS versions.
- Upgrade to PILOS version 2.3.0, where the vulnerability has been patched.
Long-Term Security Practices
- Regularly monitor for security advisories related to PILOS.
- Implement strong password policies and multi-factor authentication.
Patching and Updates
Ensure all software components, including PILOS, are regularly updated to the latest secure versions to mitigate known vulnerabilities.
