Around 45,000 Internet-exposed Jenkins servers remain unpatched against a critical arbitrary file-read vulnerability (CVE-2024-23897), allowing remote code execution. Proof-of-exploit code is available, with reports of attackers attempting to exploit. The vulnerability affects the Jenkins CLI and can lead to data theft, system compromise, and disrupted pipelines. An immediate software update is recommended to mitigate the risk.
From the meeting notes, it seems that there is a critical vulnerability affecting Jenkins servers, specifically the CVE-2024-23897. This vulnerability allows for arbitrary file-read and can lead to remote code execution on affected systems. The Jenkins infrastructure team has released updated versions to address this vulnerability, which are the new Jenkins versions 2.442 and LTS version 2.426.3. However, immediate patching is crucial to address the vulnerability.
It’s important to note that proof-of-concept exploit code is now publicly available for this vulnerability, and there are reports of attackers actively attempting to exploit it. As such, there is a high risk of data theft, system compromise, disrupted pipelines, and potential for compromised software releases.
Organizations that cannot immediately upgrade to the new Jenkins versions should disable CLI access to prevent exploitation as a workaround. Additionally, it’s recommended for development organizations to implement a least-privilege model for limiting access, conduct vulnerability scanning, and continuous monitoring for suspicious activities.
Overall, promoting security awareness among developers and administrators is crucial to strengthening the overall security posture. It is essential for organizations using Jenkins to take this vulnerability seriously and take immediate action to protect their systems.
