CVE-2024-3829

qdrant/qdrant version 1.9.0-dev is vulnerable to arbitrary file read and write during the snapshot recovery process. Attackers can exploit this vulnerability by manipulating snapshot files to include symlinks, leading to arbitrary file read by adding a symlink that points to a desired file on the filesystem and arbitrary file write by including a symlink and a payload file in the snapshots directory structure. This vulnerability allows for the reading and writing of arbitrary files on the server, which could potentially lead to a full takeover of the system. The issue is fixed in version v1.9.0.

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

Potential Mitigations

• Follow the principle of least privilege when assigning access rights to entities in a software system.
• Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
