Short explanation
An incomplete fix in DDEV pkg/archive/archive.go allows crafted tar archives to write files outside the extraction directory. Affecting versions from 1.25.2 until 1.25.4, this flaw can lead to code execution in the context of the DDEV user.
This vulnerability permits code execution by overwriting shell startup files, Git hooks, or cron entries during remote add-on retrieval, database imports, or file imports.
What should be done?
- Follow vendor advisories and updates
- Avoid using vulnerable versions where possible
- Exercise caution when importing archives from untrusted sources
Chain of evidence and sources
DDEV 1.25.2 ile 1.25.4 sürümleri arasındaki Untar işlevi, mutlak sembolik bağları ham Linkname ile oluşturarak çıkarım dizini dışına dosya yazılmasına izin verir.
Bu güvenlik açığı, kabuk başlangıç dosyalarının, Git kancalarının veya cron girdilerinin üzerine yazılarak DDEV kullanıcısının bağlamında kod yürütülmesine yol açabilir.
Show the technical text from the sources
DDEV is an open-source tool for running local web development environments for PHP and Node.js. From 1.25.2 until 1.25.4, Untar in pkg/archive/archive.go validates an absolute tar symlink target after rebasing it beneath dest, but creates the symlink with the raw absolute Linkname. A crafted archive can therefore plant a host-absolute symlink and use a following regular-file entry to write outside the extraction directory. The flaw is reachable through remote add-on retrieval and database or file imports, and overwriting shell startup files, Git hooks, or cron entries can lead to code execution in the DDEV user's context. Unzip is not affected. This issue is fixed in version 1.25.4.
