Vulnerability from cvelistv5 – Published: 2022-02-16 00:00 – Updated: 2025-10-21 23:15
VLAI?
Summary
It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CVE-2021-4034 (GCVE-0-2021-4034)

Vulnerability from cvelistv5 – Published: 2022-01-28 00:00 – Updated: 2025-10-21 23:15
VLAI?
Summary
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.

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\u0027t 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\u0027ll 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."

CVE-2019-6133 (GCVE-0-2019-6133)

Vulnerability from cvelistv5 – Published: 2019-01-11 14:00 – Updated: 2024-08-04 20:16
VLAI?
Summary
In PolicyKit (aka polkit) 0.115, the "start time" protection mechanism can be bypassed because fork() is not atomic, and therefore authorization decisions are improperly cached. This is related to lack of uid checking in polkitbackend/polkitbackendinteractiveauthority.c.
Severity ?
No CVSS data available.
CWE
  • n/a
