Developers claim it’s used by big cloud companies like Microsoft, Google Cloud, and AWS, as well as tech giants like Cisco, LinkedIn, VMware, Splunk, Intel, Arm, and Adobe.
Tenable researchers discovered a critical memory corruption vulnerability in Fluent Bit’s built-in HTTP server. The vulnerability is named Linguistic Lumberjack and has been assigned the official identifier CVE-2024-4323.
The cybersecurity firm confirmed that if someone has access to the Fluent Bit monitoring API, they can launch a DoS attack or obtain sensitive information.
Exploiting CVE-2024-4323 for RCE may be possible, but it depends on factors like the operating system and host architecture.
“While heap buffer overflows such as this are known to be exploitable, creating a reliable exploit is not only difficult, but incredibly time intensive,” Tenable explained.
On Monday, the company released technical information and a proof-of-concept (PoC) exploit for DoS attacks.
Tenable shared its findings with Fluent Bit developers in April, but the patch has not been officially released yet. The security firm also informed Microsoft, AWS, and Google Cloud about the findings on May 15th.
Users can implement mitigations for Fluent Bit by restricting access to the tool’s API and disabling any unused endpoints.
