Debian DLA-1790-1 : lemonldap-ng security update

critical Nessus Plugin ID 125266

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Erratum: bad versions

An attack vector was discovered by lemonldap-ng developers. When the SAML or CAS service provider is enable and the administrator has chosen to store SAML/CAS tokens in the session database, an attacker can open an anonymous session to connect to any protected application that does not have specific access rules.

For Debian 8 'Jessie', this problem has been fixed in version 1.3.3-1+deb9u1.

We recommend that you upgrade your lemonldap-ng packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
