CVE-2023-49070 Analysis

Apache OFBiz open-source software has recently faced a critical security bug tracked as CVE-2023-49070 that can potentially lead to RCE by allowing unauthenticated attackers to inject malicious code into vulnerable applications. This gives adversaries the green light to gain full control over the server, enabling them to steal sensitive data, disrupt operations, or potentially launch further attacks. Due to the severe risks, the vulnerability poses to impacted systems, it ranks 9.8 on the CVSS score.

The successful exploitation of CVE-2023-49070 enables adversaries to run arbitrary code on the impacted Apache OFBiz server without the need for prior authentication. 

The security flaw affects Apache OFBiz versions before Apache OFBiz before 18.12.10. CVE-2023-49070 stems from the existence of a deprecated XML-RPC component within Apache OFBiz, which is no longer being actively maintained. 

The security flaw was uncovered by the security researcher Siebene who has also authored and released its PoC exploit code. To mitigate the risks posed by CVE-2023-49070 exploitation attempts, it is essential for organizations leveraging Apache OFBiz to promptly install the required security patches and updates covered in the software version 18.12.10. Moreover, implementing proper security measures, such as input validation and output encoding, can help prevent code injection attacks and boost the overall cybersecurity posture.

With the potential risks of the CVE-2023-49070 exploitation in real-world attacks, defenders are looking for ways to enhance their cyber resilience to proactively defend against intrusions. Leveraging detection algorithms from Threat Detection Marketplace helps organizations, no matter their industry vertical and tech stack in use, identify adversary activity and effectively thwart attacks weaponizing known vulnerabilities, zero-days, or other critical threats challenging the business.
