GLSA-202401-15 : Prometheus SNMP Exporter: Basic Authentication Bypass

high Nessus Plugin ID 188000

Language:

Description

The remote host is affected by the vulnerability described in GLSA-202401-15 (Prometheus SNMP Exporter: Basic Authentication Bypass)

 - Prometheus Exporter Toolkit is a utility package to build exporters. Prior to versions 0.7.2 and 0.8.2, if someone has access to a Prometheus web.yml file and users' bcrypted passwords, they can bypass security by poisoning the built-in authentication cache. Versions 0.7.2 and 0.8.2 contain a fix for the issue. There is no workaround, but attacker must have access to the hashed password to use this functionality.
 (CVE-2022-46146)

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

Solution

All Prometheus SNMP Exporter users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=app-metrics/snmp_exporter-0.24.1
