AI-Generated

A command injection vulnerability in the rpm tool allows attackers to manipulate the path or filename of a tarball processed by `rpmbuild -t*`, potentially including shell metacharacters. This poses a significant risk in automated build or CI workflows, as successful exploitation can lead to arbitrary command execution with the privileges of the build user, resulting in information disclosure or disruption of the build environment. Organizations utilizing automated build systems should prioritize patching this vulnerability to mitigate the associated risks.

Original NVD Description

A flaw was found in rpm. An attacker can exploit a command injection vulnerability by influencing the path or filename of a tarball processed by `rpmbuild -t*` to include shell metacharacters. This is particularly relevant in automated build or continuous integration (CI) workflows that ingest externally supplied artifact names. Successful exploitation allows for arbitrary command execution with the privileges of the build user, which could lead to information disclosure or disruption of the build environment.
