Password can be used past expiry in PgBouncer due to auth_query not taking into account Postgres its VALID UNTIL value, which allows an attacker to log in with an already expired password

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Password can be used past expiry in PgBouncer due to auth_query not taking into account Postgres its VALID     UNTIL value, which allows an attacker to log in with an already expired password (CVE-2025-2291)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-4180 advisory.

    Package        : pgbouncer     Version        : 1.15.0-1+deb11u1     CVE ID         : CVE-2021-3935 CVE-2025-2291     Debian Bug     : 1103394

    PgBouncer is a lightweight connection pooler for PostgreSQL.

    CVE-2021-3539

        When PgBouncer is configured to use cert authentication, a         man-in-the-middle attacker can inject arbitrary SQL queries when a         connection is first established, despite the use of TLS certificate         verification and encryption. This flaw affects PgBouncer versions prior to         1.16.1.

    CVE-2025-2291

        Password can be used past expiry in PgBouncer due to auth_query not taking         into account Postgres its VALID UNTIL value, which allows an attacker to         log in with an already expired password

    For Debian 11 bullseye, these problems have been fixed in version     1.15.0-1+deb11u1.

    We recommend that you upgrade your pgbouncer packages.
