Nutanix AOS : Multiple Vulnerabilities (NXSA-AOS-7.3.1.6)

Synopsis

The Nutanix AOS host is affected by multiple vulnerabilities .

Description

The version of AOS installed on the remote host is prior to 7.3.1.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-7.3.1.6 advisory.

- The email module, specifically the BytesGenerator class, didn't properly quote newlines for email headers when serializing an email message allowing for header injection when an email is serialized. This is only applicable if using LiteralHeader writing headers that don't respect email folding rules, the new behavior will reject the incorrectly folded headers in BytesGenerator. (CVE-2026-1299)

- Allocation of resources for multipart headers with insufficient limits enabled a DoS vulnerability in Apache Commons FileUpload. This issue affects Apache Commons FileUpload: from 1.0 before 1.6; from 2.0.0-M1 before 2.0.0-M4. Users are recommended to upgrade to versions 1.6 or 2.0.0-M4, which fix the issue. (CVE-2025-48976)

- The imaplib module, when passed a user-controlled command, can have additional commands injected using newlines. Mitigation rejects commands containing control characters. (CVE-2025-15366)

- The poplib module, when passed a user-controlled command, can have additional commands injected using newlines. Mitigation rejects commands containing control characters. (CVE-2025-15367)

- User-controlled header names and values containing newlines can allow injecting HTTP headers.
(CVE-2026-0865)

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

Solution

Update the Nutanix AOS software to the recommended version. Before upgrading: if this cluster is registered with Prism Central, ensure that Prism Central has been upgraded first to a compatible version. Refer to the Software Product Interoperability page on the Nutanix portal.
