Severity CVSS v4.0:
HIGH
Type:
CWE-78 OS Command Injections
Publication date:
24/08/2026
Last modified:

Description

Improper Neutralization of Special Elements used in an OS Command in the package manager component of Black Duck blackduck-c-cpp before 3.0.7 allows an actor able to create a file within the scanned build directory to execute operating system commands as the account running the scan.<br /> <br /> <br /> <br /> Filesystem paths encountered while traversing the scanned directory are interpolated into command strings that are executed through a shell without quoting or escaping, so shell metacharacters within those paths are interpreted rather than treated as literal text. No control over the build command or the tool&amp;#39;s configuration is required.
