CVE-2024-39069 is a DLL hijacking vulnerability identified in ifood Order Manager version 3.35.5, specifically in the executable 'Gestor de Peddios.exe'. DLL hijacking vulnerabilities arise when an application loads dynamic link libraries (DLLs) insecurely, allowing an attacker to place a malicious DLL in a location that the application searches before the legitimate DLL. When the application loads the malicious DLL, the attacker’s code executes with the privileges of the running process. This vulnerability is classified under CWE-491, which covers improper DLL loading. The CVSS 3.1 base score is 7.8, indicating high severity, with the vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. This means the attack requires local access, low attack complexity, no privileges, and user interaction, with high impact on confidentiality, integrity, and availability. The vulnerability is significant because it allows arbitrary code execution, potentially leading to full system compromise. No patches or fixes have been published yet, and no known exploits are reported in the wild, but the risk remains substantial due to the nature of DLL hijacking. Organizations using this software should be aware of the risk and take immediate steps to mitigate exposure.

The impact of CVE-2024-39069 is severe for organizations using ifood Order Manager v3.35.5. Successful exploitation allows attackers to execute arbitrary code with the privileges of the application, potentially leading to full system compromise. This can result in unauthorized access to sensitive order and customer data, manipulation or deletion of records, disruption of order processing services, and potential lateral movement within the network. Given the high confidentiality, integrity, and availability impacts, organizations could face operational disruptions, financial losses, reputational damage, and regulatory penalties. Since the attack requires local access and user interaction, the threat is more pronounced in environments where users have access to the affected system and could be tricked into executing malicious files or opening compromised directories. The absence of patches increases the window of exposure, emphasizing the need for proactive mitigation.

To mitigate CVE-2024-39069, organizations should implement the following specific measures: 1) Restrict local user permissions to prevent unauthorized file placement in directories searched by the vulnerable executable. 2) Use application whitelisting to prevent execution of unauthorized DLLs or executables. 3) Employ endpoint detection and response (EDR) solutions to monitor for suspicious DLL loading behaviors and anomalous process executions. 4) Educate users about the risks of opening untrusted files or directories that could contain malicious DLLs. 5) Temporarily isolate or limit use of ifood Order Manager v3.35.5 in sensitive environments until a patch is released. 6) Conduct regular audits of directories used by the application to ensure no unauthorized DLLs are present. 7) Engage with the vendor for updates or patches and apply them promptly once available. 8) Consider deploying application sandboxing or containerization to limit the impact of potential code execution. These targeted actions go beyond generic advice by focusing on the specific attack vector and operational context of the vulnerability.
