high Nessus Plugin ID 280124

Language:

Synopsis

The remote host is missing a security update.

Description

The version of MongoDB installed on the remote host is 3.6.x, 4.0.x, 4.2.x, 4.4.x prior to 4.4.30, 5.0.x prior to 5.0.32, 6.0.x prior to 6.0.27, 7.0.x prior to 7.0.28, 8.0.x prior to 8.0.17, or 8.2.x prior to 8.2.3. It is, therefore, affected by a uninitialized heap memeory leak vulnerability:

 - Mismatched length fields in Zlib compressed protocol headers may allow a read of uninitialized heap memory by an unauthenticated client. (CVE-2025-14847)

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

Solution

Upgrade to MongoDB version 4.4.30, 5.0.32, 6.0.27, 7.0.28, 8.0.17, or 8.2.3 or later.
