Detailsinfo

A vulnerability was found in Cloud Foundry BOSH up to 282.1.11. It has been classified as critical. This affects the function Bosh::Common::Exec.sh of the file Exec.sh. The manipulation of the argument package_meta['name'] with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

PackagePersister.validate_tgz builds "tar -tf #{tgz} 2>&1" where tgz = File.join(release_dir, 'packages', "#{name}.tgz") and name = package_meta['name'] comes directly from release.MF inside the uploaded tarball. The string is passed to Bosh::Common::Exec.sh, which executes via %x{} — i.e., /bin/sh -c. No Shellwords.escape is applied. The Models::Package Sequel validation (VALID_ID = /^[-0-9A-Za-z_+.]+$/i) would reject the name, but in create_package (lines 74–79) the shell-out in save_package_source_blob runs before package.save, so validation fires too late. Affected versions: - BOSH: all versions prior to v282.1.12 (inclusive); fixed in v282.1.12 or later

The advisory is shared at cloudfoundry.org. This vulnerability is uniquely identified as CVE-2026-41011 since 04/16/2026. The exploitability is told to be easy. An attack has to be approached locally. The exploitation needs additional levels of successful authentication. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1202 for this issue.

Upgrading to version 282.1.12 eliminates this vulnerability.
