CVE-2019-10807Public exploitNetwork attack vector

Arbitrary command execution via unsanitized blame arguments

Published Mar 10, 2020 · Updated Aug 4, 2024

OS command injection in Andrey Kucherenko blamer before 1.0.1 allows attackers to execute arbitrary commands through crafted blame arguments. The Git and Subversion adapters concatenate supplied arguments and a file name into shell command strings passed to child_process.exec without neutralization. Exploitation requires an application to pass attacker-controlled constructor or blameByFile arguments; commands run with the application's privileges.
