Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2023:0759-1 advisory.

- Net-Server, when the reverse-lookups option is enabled, does not check if the hostname resolves to the source IP address, which might allow remote attackers to bypass ACL restrictions via the hostname parameter. (CVE-2013-1841)

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

Solution

Update the affected perl-Net-Server package.
