Foresiet Highlights Active Exploitation of Apache Flink Vulnerability

Foresiet, your trusted cybersecurity advisor, brings attention to the recent addition of a security flaw impacting Apache Flink to the Known Exploited Vulnerabilities catalog by the U.S. Cybersecurity and Infrastructure Security Agency (CISA). Tracked as CVE-2020-17519, this vulnerability poses a significant risk due to its potential for active exploitation.

Understanding the Vulnerability

CVE-2020-17519 highlights an instance of improper access control within Apache Flink, a popular open-source stream-processing and batch-processing framework. This flaw could allow an attacker to read any file on the local filesystem of the JobManager through its REST interface. Consequently, a remote, unauthenticated attacker could exploit this vulnerability to gain unauthorized access to sensitive information by sending a specially crafted directory traversal request.

Mitigating the Risk

Although the vulnerability was addressed in January 2021 with the release of Flink versions 1.11.3 or 1.12.0, evidence of active exploitation underscores the urgency for organizations to apply the latest fixes promptly. Palo Alto Networks Unit 42 has warned of extensive in-the-wild abuse of CVE-2020-17519 between November 2020 and January 2021, highlighting the severity of the threat.

Protecting Your Network

In response to the active exploitation of CVE-2020-17519, federal agencies are advised to prioritize the application of the latest fixes by June 13, 2024, to safeguard their networks against potential threats. Proactive measures, such as implementing robust patch management strategies and conducting regular security assessments, are crucial in mitigating the risks posed by such vulnerabilities.
