CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-23833 – WordPress Drop Shadow Boxes Plugin <= 1.7.10 is vulnerable to Cross Site Scripting (XSS)
https://notcve.org/view.php?id=CVE-2023-23833
Auth. (contributor+) Cross-Site Scripting (XSS) vulnerability in Steven Henty Drop Shadow Boxes plugin <= 1.7.10 versions. The Drop Shadow Boxes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in versions up to, and including, 1.7.10 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. • https://patchstack.com/database/vulnerability/drop-shadow-boxes/wordpress-drop-shadow-boxes-plugin-1-7-10-cross-site-scripting-xss-vulnerability?_s_id=cve • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

In Shadow 4.13, it is possible to inject control characters into fields provided to the SUID program chfn (change finger). Although it is not possible to exploit this directly (e.g., adding a new user fails because \n is in the block list), it is possible to misrepresent the /etc/passwd file when viewed. Use of \r manipulations and Unicode characters to work around blocking of the : character make it possible to give the impression that a new user has been added. In other words, an adversary may be able to convince a system administrator to take the system offline (an indirect, social-engineered denial of service) by demonstrating that "cat /etc/passwd" shows a rogue user account. • https://github.com/shadow-maint/shadow/commit/e5905c4b84d4fb90aefcd96ee618411ebfac663d https://github.com/shadow-maint/shadow/pull/687 https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/cve-2023-29383-abusing-linux-chfn-to-misrepresent-etc-passwd https://www.trustwave.com/en-us/resources/security-resources/security-advisories/?fid=31797 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

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). shadow versión 4.8, en determinadas circunstancias que afectan al menos a Gentoo, Arch Linux y Void Linux, permite a usuarios locales conseguir acceso root porque los programas setuid están configurados inapropiadamente. Específicamente, esto afecta a shadow versión 4.8 cuando se compila usando --with-libpam pero sin pasar explícitamente --disable-account-tools-setuid, y sin una configuración PAM adecuada para utilizar con herramientas de administración de cuentas setuid. • https://bugs.archlinux.org/task/64836 https://bugs.gentoo.org/702252 https://github.com/shadow-maint/shadow/commit/edf7547ad5aa650be868cf2dac58944773c12d75 https://github.com/shadow-maint/shadow/pull/199 https://github.com/void-linux/void-packages/pull/17580 https://security.gentoo.org/glsa/202008-09 • CWE-732: Incorrect Permission Assignment for Critical Resource •

An issue was discovered in shadow 4.5. newgidmap (in shadow-utils) is setuid and allows an unprivileged user to be placed in a user namespace where setgroups(2) is permitted. This allows an attacker to remove themselves from a supplementary group, which may allow access to certain filesystem paths if the administrator has used "group blacklisting" (e.g., chmod g-rwx) to restrict access to paths. This flaw effectively reverts a security feature in the kernel (in particular, the /proc/self/setgroups knob) to prevent this sort of privilege escalation. Se ha descubierto un problema en shadow 4.5. newgidmap (en shadow-utils) es setuid y permite que un usuario no privilegiado se coloque en un espacio de nombres de usuario en el que setgroups(2) está permitido. Esto permite que un atacante se autoelimine de un grupo suplementario, lo que podría permitir el acceso a ciertas rutas del sistema de archivos si el administrador ha empleado "listas negras de grupos" (por ejemplo, chmod g-rwx) para restringir el acceso a las rutas. • https://bugs.launchpad.net/ubuntu/+source/shadow/+bug/1729357 https://security.gentoo.org/glsa/201805-09 • CWE-732: Incorrect Permission Assignment for Critical Resource •
