Title

Arbitrary Root File Write via Path Traversal in BOSH agent

Summary

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").

Severity
