Impact
A Path Traversal Vulnerability found in the apoc.export.* procedures of apoc plugins in Neo4j Graph database. The issue allows a malicious actor to potentially break out of the expected directory. The vulnerability is such that files could only be created but not overwritten.
For the vulnerability to be exploited, an attacker would need access to execute an arbitrary query, either by having access to an authenticated Neo4j client, or a Cypher injection vulnerability in an application. The procedure would need to have been allow listed in the neo4j configuration as well as having the apoc config apoc.export.file.enabled set to true.
On a UNIX based system the following query allows arbitrary write access to the tmp folder:
CALL apoc.export.csv.query('RETURN 1', 'file:///..//..//..//..//tmp/test.txt', {})
Patches
The users should aim to use the latest released version compatible with their Neo4j version. The minimum versions containing patch for this vulnerability are 4.4.0.12 and 4.3.0.12.
Workarounds
If you cannot upgrade the library, you can control the allowlist of the procedures that can be used in your system, and/or turn off local file access by setting apoc.export.file.enabled=false

The vulnerability can be exploited over the network without needing physical access. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the integrity of the data. There is a low impact on the availability of the system.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
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.
