CVE-2024-1117 is a critical code injection vulnerability identified in openBI versions 1.0.0 through 1.0.8. The vulnerability resides in the 'index' function of the /application/index/controller/Screen.php file. Specifically, the issue arises from improper handling and sanitization of the 'fileurl' argument, which an attacker can manipulate to inject arbitrary code. This vulnerability is classified under CWE-94 (Improper Control of Generation of Code), indicating that user-supplied input is executed as code without adequate validation or sanitization. The vulnerability can be exploited remotely without requiring any authentication or user interaction, making it highly accessible to attackers. The CVSS v3.1 base score is 7.3, reflecting high severity, with attack vector network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impacts on confidentiality, integrity, and availability (C:L/I:L/A:L). Although no public exploits have been confirmed in the wild yet, the vulnerability details have been publicly disclosed, increasing the risk of exploitation by threat actors. The lack of available patches at the time of disclosure further exacerbates the risk. Given that openBI is a business intelligence platform, successful exploitation could allow attackers to execute arbitrary code on the server hosting the application, potentially leading to data breaches, unauthorized data manipulation, service disruption, or pivoting to other internal systems.

For European organizations using openBI versions up to 1.0.8, this vulnerability poses a significant risk. Exploitation could lead to unauthorized code execution on critical business intelligence infrastructure, compromising sensitive corporate data and analytics. This can result in loss of data confidentiality, integrity, and availability, potentially disrupting decision-making processes and business operations. Organizations in sectors such as finance, manufacturing, healthcare, and government, which rely heavily on BI tools for data-driven decisions, are particularly vulnerable. The remote and unauthenticated nature of the exploit increases the attack surface, allowing attackers to target exposed openBI instances over the internet. This could lead to ransomware deployment, data exfiltration, or use of the compromised system as a foothold for further attacks within the corporate network. Additionally, the public disclosure of the vulnerability details may accelerate the development and deployment of exploit tools by malicious actors, increasing the urgency for mitigation.

1. Immediate mitigation should include restricting external access to openBI instances by implementing network-level controls such as firewalls and VPNs to limit exposure to trusted users only. 2. Conduct a thorough audit of all openBI deployments to identify affected versions and isolate vulnerable instances. 3. Apply input validation and sanitization controls on the 'fileurl' parameter if custom modifications or patches are possible before an official patch is released. 4. Monitor network and application logs for unusual activity related to the 'fileurl' parameter or unexpected code execution attempts. 5. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting this vulnerability. 6. Engage with openBI vendors or community to obtain or develop patches or updates addressing this vulnerability as soon as they become available. 7. Prepare incident response plans specific to potential exploitation scenarios, including containment and recovery procedures. 8. Educate IT and security teams about this vulnerability to ensure rapid detection and response.
