Description

OpenCRX before v5.2.2 was discovered to be vulnerable to password enumeration due to the difference in error messages received during a password reset which could enable an attacker to determine if a username, email or ID is valid.

Technical Analysis

CVE-2022-40084 is a medium-severity vulnerability affecting OpenCRX versions prior to 5.2.2. The issue arises from a password enumeration weakness during the password reset process. Specifically, the system responds with different error messages depending on whether the username, email, or ID submitted exists in the system. This discrepancy allows an unauthenticated attacker to determine the validity of user identifiers by analyzing the error responses. The vulnerability is classified under CWE-203 (Information Exposure Through Discrepancy), indicating that inconsistent error handling leaks sensitive information. The CVSS 3.1 base score is 5.3, reflecting a network attack vector with low complexity, no privileges required, and no user interaction needed. The impact is limited to confidentiality, as the attacker can confirm valid user accounts but cannot alter data or disrupt availability. No known exploits are currently reported in the wild, and no official patches or vendor-specific details are provided in the source information. However, the issue can facilitate further attacks such as targeted phishing, brute force attempts, or social engineering by providing attackers with verified user identifiers.

Potential Impact

For European organizations using OpenCRX, this vulnerability can lead to increased risk of targeted attacks. By confirming valid user accounts, attackers can craft more effective phishing campaigns or attempt password guessing attacks with higher success rates. This can compromise user credentials, potentially leading to unauthorized access to sensitive customer relationship management data. Although the vulnerability itself does not allow direct data modification or service disruption, the information leakage can be a stepping stone for more severe attacks. Organizations handling personal data under GDPR must consider the reputational and regulatory risks associated with such information exposure. The impact is more pronounced for organizations with large user bases or those in sectors with high-value data, such as finance, healthcare, or government services.

Mitigation Recommendations

To mitigate this vulnerability, European organizations should first upgrade OpenCRX to version 5.2.2 or later where the issue is resolved. In the absence of an official patch, organizations can implement uniform error messages during the password reset process to prevent attackers from distinguishing valid from invalid user identifiers. Rate limiting password reset requests and monitoring for abnormal request patterns can help detect and block enumeration attempts. Additionally, implementing multi-factor authentication (MFA) reduces the risk of account compromise even if user identifiers are exposed. Security teams should also conduct regular audits of authentication workflows and educate users about phishing risks. Finally, logging and alerting on suspicious password reset activities can provide early warning of enumeration attempts.
