CVE-2022-42983: n/a in n/a
anji-plus AJ-Report 0.9.8.6 allows remote attackers to bypass login authentication by spoofing JWT Tokens.
AI Analysis
Technical Summary
CVE-2022-42983 is a high-severity vulnerability affecting anji-plus AJ-Report version 0.9.8.6. The vulnerability allows remote attackers to bypass login authentication by spoofing JSON Web Tokens (JWTs). JWTs are widely used for stateless authentication in web applications, where the server trusts the token's signature to verify the user's identity and permissions. In this case, the vulnerability arises because the application does not properly validate the JWT tokens, enabling attackers to craft or manipulate tokens that the system accepts as valid without requiring legitimate credentials. This effectively allows unauthorized access to the application and its functionalities. The CVSS 3.1 base score is 8.8, indicating a high impact on confidentiality, integrity, and availability. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), and low privileges (PR:L), with no user interaction (UI:N) needed. The vulnerability scope is unchanged (S:U), meaning the impact is confined to the vulnerable component. The CWE classification is CWE-290, which corresponds to improper authentication. No patches or known exploits in the wild have been reported as of the publication date. However, the lack of patch availability increases the urgency for mitigation. The vulnerability could allow attackers to gain unauthorized access to sensitive data, modify or delete reports, and disrupt service availability by abusing the compromised authentication mechanism.
Potential Impact
For European organizations using anji-plus AJ-Report 0.9.8.6, this vulnerability poses a significant risk. Unauthorized access through JWT spoofing can lead to data breaches involving sensitive business intelligence, reporting data, and potentially personally identifiable information (PII) if such data is processed or stored within the application. The integrity of reports and analytics can be compromised, leading to incorrect business decisions or regulatory compliance issues. Availability may also be affected if attackers disrupt reporting services. Given the GDPR and other strict data protection regulations in Europe, exploitation of this vulnerability could result in legal penalties and reputational damage. Organizations relying on AJ-Report for critical reporting functions should consider the risk of insider threats or external attackers exploiting this flaw to gain elevated privileges or persist within networks.
Mitigation Recommendations
Since no official patches are currently available, European organizations should implement immediate compensating controls. These include: 1) Restricting network access to the AJ-Report application to trusted IP ranges or VPN-only access to reduce exposure. 2) Implementing Web Application Firewalls (WAFs) with custom rules to detect and block malformed or suspicious JWT tokens. 3) Enforcing multi-factor authentication (MFA) at the perimeter or identity provider level to add an additional authentication layer beyond JWT tokens. 4) Conducting thorough logging and monitoring of authentication attempts and JWT usage to detect anomalies. 5) Reviewing and hardening JWT validation logic if source code or configuration access is available, ensuring tokens are properly verified against trusted signing keys and algorithms. 6) Planning for an urgent upgrade or patch deployment once a fix is released by the vendor or community. 7) Educating users and administrators about the risk and signs of compromise related to this vulnerability.
