CVE-2020-28446Public exploitNetwork attack vector

Arbitrary command execution via unquoted image argument

Published Jul 25, 2022 · Updated Sep 17, 2024

Command injection in Tao Yuan nTesseract before 0.2.9 allows remote attackers to execute arbitrary OS commands through a crafted image argument. The command() function in lib/tesseract.js concatenates the caller-controlled image value into a shell command string and passes it to child_process.exec without shell-safe argument handling. Exploitation requires a consuming Node.js application to pass attacker-controlled image input to process(), after which commands run with the application's privileges.
