Debian DLA-3496-1 : lemonldap-ng - LTS security update

critical Nessus Plugin ID 178300

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3496 advisory.

- An issue was discovered in LemonLDAP::NG before 2.16.1. Weak session ID generation in the AuthBasic handler and incorrect failure handling during a password check allow attackers to bypass 2FA verification.
Any plugin that tries to deny session creation after the store step does not deny an AuthBasic session.
(CVE-2023-28862)

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

Solution

Upgrade the lemonldap-ng packages.

For Debian 10 buster, these problems have been fixed in version 2.0.2+ds-7+deb10u9.
