Vulnerability Published: 2020-12-07
Patch Published: 2020-10-28
CVE [?]: CVE-2020-13945
CPE [?]: cpe:/a:apache:apisix

Synopsis

An application installed on the remote host is missing a vendor-supplied update.

Description

The version of Apache APISIX installed on the remote host is 1.2 prior to or equal to 1.5. It is, therefore, affected by an information disclosure vulnerability. An authenticated, remote attacker could exploit this to access Apache APISIX management data.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache APISIX version 2.0 or later.

Public Exploits

Target Network Port(s): N/A
Target Asset(s): N/A
Exploit Available: True (Metasploit Framework, GitHub)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the Apache APISIX 1.2 <= 1.5 Information Disclosure vulnerability:

Metasploit: exploit/multi/http/apache_apisix_api_default_token_rce
[APISIX Admin API default access token RCE]
