CVE-2021-3560

HIGH KEV

polkit < 0.119 - Unauthenticated Privilege Escalation via D-Bus Request

Title source: llm
STIX 2.1

Exploitation Summary

CVE-2021-3560 is actively exploited and listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, added May 12, 2023. EIP tracks 36 public exploits from researchers including J Smith, Almorabea, secnigma, including a Metasploit module exploits/linux/local/polkit_dbus_auth_bypass.

AI-analyzed exploit summary This exploit leverages a race condition in Polkit's dbus interface to create a new user with administrative privileges and set a password, allowing local privilege escalation to root. It uses timing-based exploitation to bypass authentication checks.

Description

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.
