Detailsinfo

A vulnerability classified as very critical has been found in CloudFoundry BOSH up to 2.846.x. Affected is an unknown part of the component Agent. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Path Traversal in BOSH-Ecosystem / BOSH allows an IaaS-metadata attacker to make the agent write a root-owned file with partially attacker-controlled body to any path ending in .network, and create any missing parent directories with mode 0777 via network Alias on Ubuntu. Affected versions: BOSH agent < v2.847.0 (jammy <= v1.1202, or noble <= v1.364). Lower bound unspecified in advisory ("All bosh agent versions").
