Amazon Linux 2 : ceph-common (ALAS-2023-2297)

medium Nessus Plugin ID 183483

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of ceph-common installed on the remote host is prior to 10.2.5-4. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2297 advisory.

 A flaw was found in rgw. This flaw allows an unprivileged user to write to any bucket(s) accessible by a given key if a POST's form-data contains a key called 'bucket' with a value matching the bucket's name used to sign the request. This issue results in a user being able to upload to any bucket accessible by the specified access key as long as the bucket in the POST policy matches the bucket in the said POST form part. (CVE-2023-43040)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update ceph-common' to update your system.
