Summary
An authenticated SQL injection vulnerability in the elFinder MySQL volume driver (elFinderVolumeMySQL) allows any logged-in user, including users with read-only access to the affected volume, to inject SQL through a crafted target file hash. Successful exploitation can lead to unauthorized data disclosure and denial of service.
This vulnerability only affects installations configured to use the MySQL volume driver. Installations using the default LocalFileSystem driver are not affected.
Description
A vulnerability in elFinder's MySQL volume driver (elFinderVolumeMySQL) allows authenticated SQL injection through a crafted file hash passed via the target parameter.
The issue is caused by two behaviors working together:
- File hashes are decoded without validating that the decoded value is a valid MySQL object identifier.
- The decoded value is then used in MySQL driver queries, including
cacheDir(),_joinPath(),_stat(), and_fopen().
Because the MySQL storage schema uses numeric id and parent_id values, an authenticated user can supply a crafted hash that alters the intended SQL query logic. Successful exploitation can lead to unauthorized data disclosure and denial of service. The extent of impact depends on the privileges granted to the configured MySQL account.
This vulnerability only affects installations configured to use the MySQL volume driver. Installations using the default LocalFileSystem driver are not affected.
Impact
An authenticated user, including a user with read-only access to the affected volume, can exploit this issue to:
- disclose data accessible to the configured MySQL account, including file contents stored by the driver and database metadata
- trigger denial of service through expensive or unexpectedly broad query results that can lead to excessive memory consumption
The severity of data exposure depends on the privileges granted to the configured MySQL account.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
