CVE-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 •
CVE-2019-20807 – vim: users can execute arbitrary OS commands via scripting interfaces in the rvim restricted mode
https://notcve.org/view.php?id=CVE-2019-20807
In Vim before 8.1.0881, users can circumvent the rvim restricted mode and execute arbitrary OS commands via scripting interfaces (e.g., Python, Ruby, or Lua). En Vim versiones anteriores a 8.1.0881, los usuarios pueden omitir el modo restringido rvim y ejecutar comandos arbitrarios de Sistema Operativo por medio de interfaces de scripting (por ejemplo, Python, Ruby o Lua). A flaw was found in vim in the restricted mode, where all commands that make use of external shells are disabled. However, it was found that users could still execute some arbitrary OS commands in the restricted mode. This flaw was fixed by filtering the functions that can call OS commands. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00018.html http://seclists.org/fulldisclosure/2020/Jul/24 https://github.com/vim/vim/commit/8c62a08faf89663e5633dc5036cd8695c80f1075 https://github.com/vim/vim/releases/tag/v8.1.0881 https://lists.debian.org/debian-lts-announce/2022/01/msg00003.html https://support.apple.com/kb/HT211289 https://usn.ubuntu.com/4582-1 https://www.starwindsoftware.com/security/sw-20220812-0003 https://access.redhat.com/security/cve/CVE-2019 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
