Nutanix AOS : Multiple Vulnerabilities (NXSA-AOS-7.3.1.2)

Synopsis

The Nutanix AOS host is affected by multiple vulnerabilities .

Description

The version of AOS installed on the remote host is prior to 7.3.1.2. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-7.3.1.2 advisory.

- A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system. (CVE-2025-32990)

- Apache CXF stores large stream based messages as temporary files on the local filesystem. A bug was introduced which means that the entire temporary file is read into memory and then logged. An attacker might be able to exploit this to cause a denial of service attack by causing an out of memory exception.
In addition, it is possible to configure CXF to encrypt temporary files to prevent sensitive credentials from being cached unencrypted on the local filesystem, however this bug means that the cached files are written out to logs unencrypted. Users are recommended to upgrade to versions 3.5.11, 3.6.6, 4.0.7 or 4.1.1, which fixes this issue. (CVE-2025-48795)

- Vim is an open source, command line text editor. Prior to version 9.1.1552, a path traversal issue in Vim's tar.vim plugin can allow overwriting of arbitrary files when opening specially crafted tar archives.
Impact is low because this exploit requires direct user interaction. However, successfully exploitation can lead to overwriting sensitive files or placing executable code in privileged locations, depending on the permissions of the process editing the archive. The victim must edit such a file using Vim which will reveal the filename and the file content, a careful user may suspect some strange things going on.
Successful exploitation could results in the ability to execute arbitrary commands on the underlying operating system. Version 9.1.1552 contains a patch for the vulnerability. (CVE-2025-53905)

- Vim is an open source, command line text editor. Prior to version 9.1.1551, a path traversal issue in Vim's zip.vim plugin can allow overwriting of arbitrary files when opening specially crafted zip archives.
Impact is low because this exploit requires direct user interaction. However, successfully exploitation can lead to overwriting sensitive files or placing executable code in privileged locations, depending on the permissions of the process editing the archive. The victim must edit such a file using Vim which will reveal the filename and the file content, a careful user may suspect some strange things going on.
Successful exploitation could results in the ability to execute arbitrary commands on the underlying operating system. Version 9.1.1551 contains a patch for the vulnerability. (CVE-2025-53906)

- A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high. (CVE-2025-26465)

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.
