"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0765 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2024-22018:
    A vulnerability has been identified in Node.js, affecting users of the experimental permission model when
    the --allow-fs-read flag is used.
    This flaw arises from an inadequate permission model that fails to restrict file stats through the
    fs.lstat API. As a result, malicious actors can retrieve stats from files that they do not have explicit
    read access to.
    This vulnerability affects all users using the experimental permission model in Node.js 20 and Node.js 21.
    Please note that at the time this CVE was issued, the permission model is an experimental feature of
    Node.js.

    CVE-2024-22020:
    A security flaw in Node.js  allows a bypass of network import restrictions.
    By embedding non-network imports in data URLs, an attacker can execute arbitrary code, compromising system
    security.
    Verified on various platforms, the vulnerability is mitigated by forbidding data URLs in network imports.
    Exploiting this flaw can violate network import security, posing a risk to developers and servers.

    CVE-2024-28863:
    node-tar is a Tar for Node.js. node-tar prior to version 6.2.1 has no limit on the number of sub-folders
    created in the folder creation process. An attacker who generates a large number of sub-folders can
    consume memory on the system running node-tar and even crash the Node.js client within few seconds of
    running it using a path with too many sub-folders inside. Version 6.2.1 fixes this issue by preventing
    extraction in excessively deep sub-folders.

    CVE-2024-36137:
    A vulnerability has been identified in Node.js, affecting users of the experimental permission model when
    the --allow-fs-write flag is used.

    Node.js Permission Model do not operate on file descriptors, however, operations such as fs.fchown or
    fs.fchmod can use a read-only file descriptor to change the owner and permissions of a file.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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