Remote code execution via uncontained file paths
Published Oct 25, 2024 · Updated Oct 25, 2024
Arbitrary file write in Plenti before 0.7.2 allows remote attackers to write outside a served site's project via /postLocal. The postLocal handler passes each JSON File value directly to os.WriteFile after only prefixing absolute paths with a dot, leaving traversal paths uncontained. The endpoint is exposed only while the serve command runs, and a crafted write can replace host files with the process's privileges and enable code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <0.7.2
- Affected versionversion=< 0.7.2
