There is no fixed version for dbgate-api.
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 insufficient validation of file paths and types in the reader function. An attacker can access arbitrary files on the system, including sensitive files, by submitting crafted requests that specify unauthorized file paths.
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
