The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-7b52921cae advisory.
When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application can intercept the operation and return a forged checksum to the node’s policy implementation, thus effectively disabling the integrity check. Impacts: This vulnerability affects all users using the experimental policy mechanism in all active release lines: 18.x and, 20.x. Please note that at the time this CVE was issued, the policy mechanism is an experimental feature of Node.js. (CVE-2023-38552)
A previously disclosed vulnerability (CVE-2023-30584) was patched insufficiently in commit 205f1e6. The new path traversal vulnerability arises because the implementation does not protect itself against the application overwriting built-in utility functions with user-defined implementations. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js. (CVE-2023-39331)
Various node:fs
functions allow specifying paths as either strings or Uint8Array
objects. In Node.js environments, the Buffer
class extends the Uint8Array
class. Node.js prevents path traversal through strings (see CVE-2023-30584) and Buffer
objects (see CVE-2023-32004), but not through non-Buffer
Uint8Array
objects. This is distinct from CVE-2023-32004 which only referred to Buffer
objects.
However, the vulnerability follows the same pattern using Uint8Array
instead of Buffer
. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.
(CVE-2023-39332)
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)
Undici is an HTTP/1.1 client written from scratch for Node.js. Prior to version 5.26.2, Undici already cleared Authorization headers on cross-origin redirects, but did not clear Cookie
headers. By design, cookie
headers are forbidden request headers, disallowing them to be set in RequestInit.headers in browser environments. Since undici handles headers more liberally than the spec, there was a disconnect from the assumptions the spec made, and undici’s implementation of fetch. As such this may lead to accidental leakage of cookie to a third-party site or a malicious attacker who can control the redirection target (ie. an open redirector) to leak the cookie to the third party site. This was patched in version 5.26.2. There are no known workarounds. (CVE-2023-45143)
Maliciously crafted export names in an imported WebAssembly module can inject JavaScript code. The injected code may be able to access data and functions that the WebAssembly module itself does not have access to, similar to as if the WebAssembly module was a JavaScript module. Impacts: Thanks to dittyroma for reporting the issue and to Tobias Nieen for fixing it. (CVE-2023-39333)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
