Nutanix AOS : Multiple Vulnerabilities (NXSA-AOS-7.3.1.1)

high Nessus Plugin ID 272046

Synopsis

The Nutanix AOS host is affected by multiple vulnerabilities .

Description

The version of AOS installed on the remote host is prior to 7.3.1.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-7.3.1.1 advisory.

- A vulnerability has been identified in the libarchive library, specifically within the archive_read_format_rar_seek_data() function. This flaw involves an integer overflow that can ultimately lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption, enabling an attacker to execute arbitrary code or cause a denial-of-service condition. (CVE-2025-5914)

- A flaw was found in linux-pam. The module pam_namespace may use access user-controlled paths without proper protection, allowing local users to elevate their privileges to root via multiple symlink attacks and race conditions. (CVE-2025-6020)

- There is a defect in the CPython tarfile module affecting the TarFile extraction and entry enumeration APIs. The tar implementation would process tar archives with negative offsets without error, resulting in an infinite loop and deadlock during the parsing of maliciously crafted tar archives. This vulnerability can be mitigated by including the following patch after importing the tarfile module:
https://gist.github.com/sethmlarson/1716ac5b82b73dbcbf23ad2eff8b33e1 (CVE-2025-8194)

- AIDE is an advanced intrusion detection environment. Prior to version 0.19.2, there is an improper output neutralization vulnerability in AIDE. An attacker can craft a malicious filename by including terminal escape sequences to hide the addition or removal of the file from the report and/or tamper with the log output. A local user might exploit this to bypass the AIDE detection of malicious files. Additionally the output of extended attribute key names and symbolic links targets are also not properly neutralized. This issue has been patched in version 0.19.2. A workaround involves configuring AIDE to write the report output to a regular file, redirecting stdout to a regular file, or redirecting the log output written to stderr to a regular file. (CVE-2025-54389)

- setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. A path traversal vulnerability in `PackageIndex` is present in setuptools prior to version 78.1.1. An attacker would be allowed to write files to arbitrary locations on the filesystem with the permissions of the process running the Python code, which could escalate to remote code execution depending on the context. Version 78.1.1 fixes the issue. (CVE-2025-47273)

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.
