    Synopsis
    ========

    A vulnerability has been found in Prometheus SNMP Exporter which could
    allow for authentication bypass.

    Background
    ==========

    The Prometheus SNMP Exporter is the recommended way to expose SNMP data
    in a format which Prometheus can ingest.

    Affected packages
    =================

    Package Vulnerable Unaffected
    ------------------------- ------------ ------------
    app-metrics/snmp_exporter < 0.24.1 >= 0.24.1

    Description
    ===========

    A vulnerability has been discovered in Prometheus SNMP Exporter. Please
    review the CVE identifier referenced below for details.

    Impact
    ======

    A user who knows the password hash of a user capable of performing HTTP
    basic authentication with a vulnerable exporter can use the hash to successfully authenticate as that user via cache manipulation, without
    knowing the password from which the hash was derived.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

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

    # emerge --sync
