CVSS Score | 6.1 |
CVSS Vector | CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N |
Description
Impact
Versions of Express.js prior to 4.19.2 and pre-release alpha and beta versions before 5.0.0-beta.3 are affected by an open redirect vulnerability using malformed URLs.
When a user of Express performs a redirect using a user-provided URL Express performs an encode using
encodeurl
on the contents before passing it to thelocation
header. This can cause malformed URLs to be evaluated in unexpected ways by common redirect allow list implementations in Express applications, leading to an Open Redirect via bypass of a properly implemented allow list.The main method impacted is
res.location()
but this is also called from withinres.redirect()
.Patches
expressjs/express@0867302
expressjs/express@0b74695An initial fix went out with
express@4.19.0
, we then patched a feature regression in4.19.1
and added improved handling for the bypass in4.19.2
.Workarounds
The fix for this involves pre-parsing the url string with either
require('node:url').parse
ornew URL
. These are steps you can take on your own before passing the user input string tores.location
orres.redirect

CVSS Score | 6.5 |
CVSS Vector | CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N |
Description
When using axios, its dependency follow-redirects only clears authorization header during cross-domain redirect, but allows the proxy-authentication header which contains credentials too.
Steps To Reproduce & PoC
Test code:
const axios = require('axios'); axios.get('http://127.0.0.1:10081/', { headers: { 'AuThorization': 'Rear Test', 'ProXy-AuthoriZation': 'Rear Test', 'coOkie': 't=1' } }) .then((response) => { console.log(response); })When I meet the cross-domain redirect, the sensitive headers like authorization and cookie are cleared, but proxy-authentication header is kept.
Impact
This vulnerability may lead to credentials leak.
Recommendations
Remove proxy-authentication header during cross-domain redirect
Recommended Patch
- removeMatchingHeaders(/^(?:authorization|cookie)$/i, this._options.headers); + removeMatchingHeaders(/^(?:authorization|proxy-authorization|cookie)$/i, this._options.headers);

shadow 1:4.13+dfsg1-1
(deb)
pkg:deb/debian/shadow@1:4.13+dfsg1-1?os_distro=bookworm&os_name=debian&os_version=12
Affected range | >=1:4.13+dfsg1-1 |
Fixed version | Not Fixed |
Description
shadow 4.8, in certain circumstances affecting at least Gentoo, Arch Linux, and Void Linux, allows local users to obtain root access because setuid programs are misconfigured. Specifically, this affects shadow 4.8 when compiled using --with-libpam but without explicitly passing --disable-account-tools-setuid, and without a PAM configuration suitable for use with setuid account management tools. This combination leads to account management tools (groupadd, groupdel, groupmod, useradd, userdel, usermod) that can easily be used by unprivileged local users to escalate privileges to root in multiple ways. This issue became much more relevant in approximately December 2019 when an unrelated bug was fixed (i.e., the chmod calls to suidusbins were fixed in the upstream Makefile which is now included in the release version 4.8).
Affected range | >=1:4.13+dfsg1-1 |
Fixed version | Not Fixed |
Description
initscripts in rPath Linux 1 sets insecure permissions for the /var/log/btmp file, which allows local users to obtain sensitive information regarding authentication attempts. NOTE: because sshd detects the insecure permissions and does not log certain events, this also prevents sshd from logging failed authentication attempts by remote attackers.

Affected range | >=3.0.11-1~deb12u2 |
Fixed version | Not Fixed |
Description
OpenSSL 0.9.8i on the Gaisler Research LEON3 SoC on the Xilinx Virtex-II Pro FPGA uses a Fixed Width Exponentiation (FWE) algorithm for certain signature calculations, and does not verify the signature before providing it to a caller, which makes it easier for physically proximate attackers to determine the private key via a modified supply voltage for the microprocessor, related to a "fault-based attack."
Affected range | >=3.0.11-1~deb12u2 |
Fixed version | Not Fixed |
Description
The NIST SP 800-90A default statement of the Dual Elliptic Curve Deterministic Random Bit Generation (Dual_EC_DRBG) algorithm contains point Q constants with a possible relationship to certain "skeleton key" values, which might allow context-dependent attackers to defeat cryptographic protection mechanisms by leveraging knowledge of those values.
