CVE-2024-7314 is an authentication bypass vulnerability classified under CWE-288 affecting the anji-plus AJ-Report product. The flaw arises because the application fails to properly validate authentication when an attacker appends the string ";swagger-ui" to HTTP requests. This alternate path or channel allows an unauthenticated remote attacker to bypass the authentication mechanism entirely. Once bypassed, the attacker can execute arbitrary Java code on the server hosting AJ-Report, effectively gaining full control over the system. The vulnerability is remotely exploitable without any user interaction or prior authentication, making it highly dangerous. The CVSS v3.1 base score is 9.8, reflecting critical severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The impact includes complete compromise of confidentiality, integrity, and availability of the affected system. Although no confirmed public exploits exist, Shadowserver Foundation observed exploitation attempts shortly after the vulnerability was published in August 2024. The affected version is listed as "0", which likely indicates early or initial releases of AJ-Report. The lack of available patches at the time of reporting increases the urgency for defensive measures. This vulnerability is particularly concerning because it leverages an alternate path in the web interface, a common vector for bypassing security controls. Organizations running AJ-Report should consider immediate network-level mitigations and closely monitor for suspicious activity targeting the ";swagger-ui" endpoint.

For European organizations, the impact of CVE-2024-7314 is severe. Successful exploitation allows attackers to bypass authentication and execute arbitrary code remotely, leading to full system compromise. This can result in data breaches, unauthorized data manipulation, service disruption, and potential lateral movement within networks. Organizations using AJ-Report for reporting or analytics may face exposure of sensitive business or personal data, violating GDPR and other data protection regulations. Critical infrastructure or government entities relying on AJ-Report could experience operational disruptions or espionage. The ease of exploitation and lack of authentication requirements increase the risk of widespread attacks. Additionally, the ability to execute arbitrary Java code could allow attackers to deploy ransomware, backdoors, or other malware, amplifying the threat. The absence of patches at the time of disclosure means organizations must rely on mitigations to reduce risk. Overall, the vulnerability poses a critical threat to confidentiality, integrity, and availability of affected systems in Europe.

1. Immediately restrict access to the AJ-Report web interface, especially the ";swagger-ui" endpoint, using network segmentation, IP whitelisting, or VPN access controls. 2. Deploy web application firewalls (WAFs) with custom rules to detect and block HTTP requests containing ";swagger-ui" or suspicious query strings that attempt authentication bypass. 3. Monitor web server and application logs for unusual access patterns or attempts to append ";swagger-ui" to URLs. 4. Disable or remove any unused or unnecessary Swagger UI components if feasible, reducing the attack surface. 5. Engage with the vendor anji-plus for updates and patches; prioritize patching as soon as a fix is released. 6. Conduct internal audits to identify all instances of AJ-Report deployments and assess exposure. 7. Implement strict Java runtime security policies and sandboxing to limit the impact of arbitrary code execution. 8. Educate security teams and incident responders about this vulnerability and prepare for potential incident response. 9. Consider deploying intrusion detection systems (IDS) signatures targeting this vulnerability’s exploitation patterns. 10. If immediate patching is not possible, consider temporary shutdown or isolation of vulnerable AJ-Report instances until mitigations are in place.
