CVE-2024-25626
CWE-78Published: February 19, 2024· Updated: Jun 17, 2026
Official Description
Yocto Project is an open source collaboration project that helps developers create custom Linux-based systems regardless of the hardware architecture. In Yocto Projects Bitbake before 2.6.2 (before and included Yocto Project 4.3.1), with the Toaster server (included in bitbake) running, missing input validation allows an attacker to perform a remote code execution in the server's shell via a crafted HTTP request. Authentication is not necessary. Toaster server execution has to be specifically run and is not the default for Bitbake command line builds, it is only used for the Toaster web based user interface to Bitbake. The fix has been backported to the bitbake included with Yocto Project 5.0, 3.1.31, 4.0.16, and 4.3.2.
Risk Analysis
The Toaster web interface in Yocto Project's Bitbake allows unauthenticated remote code execution due to missing input validation. This critical vulnerability allows attackers to execute commands in the server's shell.
No public exploit is known, and it is not in the KEV database. The vulnerability is remotely exploitable with low attack complexity.
Upgrade Bitbake to version 2.6.2 or the backported versions provided in Yocto Project 5.0, 3.1.31, 4.0.16, or 4.3.2.
Technical Analysis
CVE-2024-25626 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
