About this tag
BusyBox is a compact collection of Unix utilities widely used in embedded systems, containers, initramfs images, and minimal Linux distributions. On WindowsForum.com, discussions focus on security vulnerabilities affecting BusyBox components, including CVE-2022-28391 where netstat can be exploited via DNS PTR records containing terminal escape sequences, CVE-2025-60876 where wget allows HTTP request smuggling through crafted URLs, CVE-2025-46394 where tar misrepresents filenames using terminal escapes, and CVE-2024-58251 where netstat can lock terminals via ANSI escape sequences. These threads cover detection, mitigation, and real-world risks for administrators and security professionals.

    BusyBox CVE-2022-28391: Terminal Escape Attacks via DNS PTR Records

    BusyBox’s netstat can be turned into a surprisingly powerful attack vector: a crafted DNS PTR response that contains terminal escape sequences can make netstat emit control codes to a VT‑compatible terminal, leading not just to garish color changes but to command execution and sustained...

    CVE-2024-58251: BusyBox Netstat Escape Sequences Lock Terminal (DoS)

    BusyBox’s netstat utility has a low‑scored but real weakness: CVE‑2024‑58251 allows a local attacker to craft an application name (argv[0]) containing ANSI terminal escape sequences that, when viewed by an unsuspecting user running BusyBox netstat, can lock up the victim’s terminal and cause a...
