TencentOS Server 3: nodejs:20 (TSSA-2024:0109)

high Nessus Plugin ID 239038

Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

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-2024:0109 advisory.

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

CVE-2023-46809:
A flaw was found in Node.js. The privateDecrypt() API of the crypto library may allow a covert timing side-channel during PKCS#1 v1.5 padding error handling. This issue revealed significant timing differences in decryption for valid and invalid ciphertexts, which may allow a remote attacker to decrypt captured RSA ciphertexts or forge signatures, especially in scenarios involving API endpoints processing JSON Web Encryption messages.

CVE-2024-21890:
A flaw was found in the Node.js Permission Model, where it is not clarified in the documentation that wildcards should only be used as the last character of a file path. For example: --allow-fs- read=/home/node/.ssh/*.pub will ignore pub and give access to everything after .ssh/.

CVE-2024-21891:
A flaw was found in Node.js. Node.js depends on multiple built-in utility functions to normalize paths provided to node:fs functions, which can be overwritten with user-defined implementations, leading to a filesystem permission model bypass through a path traversal attack.

CVE-2024-21892:
A flaw was found in Node.js. On Linux, Node.js ignores certain environment variables if an unprivileged user has set them while the process is running with elevated privileges, except for CAP_NET_BIND_SERVICE.
Due to a bug in the implementation of this exception, Node.js incorrectly applies this exception even when other capabilities have been set. This flaw allows unprivileged users to inject code that inherits the process's elevated privileges.

CVE-2024-21896:
A flaw was found in Node.js. The permission model protects itself against path traversal attacks by calling path.resolve() on any paths given by the user. If the path is to be treated as a buffer, the implementation uses Buffer.from() to obtain a buffer from the result of path.resolve(). By monkey-patching buffer internals, namely, Buffer.prototype.utf8Write, the application can modify the result of path.resolve(), which leads to a path traversal vulnerability.

CVE-2024-22017:
A flaw was found in Node.js, where the setuid() does not affect libuv's internal io_uring operations if initialized before the call to setuid(). This issue allows the process to perform privileged operations despite presumably having dropped such privileges through a call to setuid().

CVE-2024-22019:
A flaw was found in Node.js due to a lack of safeguards on chunk extension bytes. The server may read an unbounded number of bytes from a single connection, which can allow an attacker to send a specially crafted HTTP request with chunked encoding, leading to resource exhaustion and a denial of service.

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.

Solution

Update the affected packages.
