CVSS: 7.8EPSS: 0%CPEs: 56EXPL: 33CVE-2021-4034 – Red Hat Polkit Out-of-Bounds Read and Write Vulnerability
https://notcve.org/view.php?id=CVE-2021-4034
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. • https://github.com/dzonerzy/poc-cve-2021-4034 https://github.com/arthepsy/CVE-2021-4034 https://github.com/berdav/CVE-2021-4034 https://www.exploit-db.com/exploits/50689 https://github.com/PwnFunction/CVE-2021-4034 https://github.com/joeammond/CVE-2021-4034 https://github.com/nikaiw/CVE-2021-4034 https://github.com/ryaagard/CVE-2021-4034 https://github.com/Rvn0xsy/CVE-2021-4034 https://github.com/Ayrx/CVE-2021-4034 https://github.com/zhzyker/CVE-2021-4034& • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

In strongSwan before 5.9.5, a malicious responder can send an EAP-Success message too early without actually authenticating the client and (in the case of EAP methods with mutual authentication and EAP-only authentication for IKEv2) even without server authentication. En strongSwan versiones anteriores a 5.9.5, un respondedor malicioso puede enviar un mensaje EAP-Success demasiado pronto sin autenticar realmente al cliente y (en el caso de los métodos EAP con autenticación mutua y autenticación sólo EAP para IKEv2) incluso sin autenticación del servidor • https://www.strongswan.org/blog/2022/01/24/strongswan-vulnerability-%28cve-2021-45079%29.html • CWE-476: NULL Pointer Dereference •

USBView 2.1 before 2.2 allows some local users (e.g., ones logged in via SSH) to execute arbitrary code as root because certain Polkit settings (e.g., allow_any=yes) for pkexec disable the authentication requirement. Code execution can, for example, use the --gtk-module option. This affects Ubuntu, Debian, and Gentoo. USBView versiones 2.1 anteriores a 2.2, permite a algunos usuarios locales (por ejemplo, los que son conectados por SSH) ejecutar código arbitrario como root porque determinadas configuraciones de Polkit (por ejemplo, allow_any=yes) para pkexec deshabilitan el requisito de autenticación. Una ejecución de código puede, por ejemplo, usar la opción --gtk-module. • http://www.openwall.com/lists/oss-security/2022/01/22/1 https://github.com/gregkh/usbview/commit/bf374fa4e5b9a756789dfd88efa93806a395463b https://security.gentoo.org/glsa/202310-15 https://www.debian.org/security/2022/dsa-5052 https://www.openwall.com/lists/oss-security/2022/01/21/1 • CWE-306: Missing Authentication for Critical Function •
