Upgrade dbgate-api to version 6.5.0 or higher.
Overview
dbgate-api is an Allows run DbGate data-manipulation scripts.
Affected versions of this package are vulnerable to Arbitrary File Write via Archive Extraction (Zip Slip) via the file parameter in the /uploads/get endpoint. An attacker can access arbitrary files on the system by supplying a crafted path to this parameter, potentially exposing sensitive data.
Details
It is exploited using a specially crafted zip archive, that holds path traversal filenames. When exploited, a filename in a malicious archive is concatenated to the target extraction directory, which results in the final path ending up outside of the target folder. For instance, a zip may hold a file with a "../../file.exe" location and thus break out of the target folder. If an executable or a configuration file is overwritten with a file containing malicious code, the problem can turn into an arbitrary code execution issue quite easily.
The following is an example of a zip archive with one benign file and one malicious file. Extracting the malicous file will result in traversing out of the target folder, ending up in /root/.ssh/ overwriting the authorized_keys file:
+2018-04-15 22:04:29 ..... 19 19 good.txt
+2018-04-15 22:04:42 ..... 20 20 ../../../../../../root/.ssh/authorized_keys
