Multiple programming languages are affected by a serious vulnerability, ‘BatBadBut’, allowing command injection in Windows applications, due to improper escape of command arguments when executing batch files. The flaw, affecting languages’ runtimes, enables attackers to inject commands into Windows applications. Some affected languages have issued patches, but successful exploitation requires specific conditions.
Based on the meeting notes, the critical-severity vulnerability named ‘BatBadBut’ affects multiple programming languages on Windows, due to the failure to escape command arguments properly when executing batch files. This enables attackers to potentially inject commands into Windows applications, rendering them vulnerable.
Although most applications are not affected, it’s essential for developers to be aware of the issue and apply mitigations. Notably, the CERT Coordination Center has issued four CVE identifiers for this security defect, but programming languages are impacted by one or two of them at most.
It’s been reported that several programming languages, including Haskell, Rust, and yt-dlp, have announced patches to address this vulnerability, while recommendations have been made for applications without a patch to perform data escaping and neutralization to prevent unintended command execution.
This vulnerability has wide-ranging implications for software development, and it’s crucial for affected parties to implement the necessary measures to protect their systems and applications.
