Improper Privilege Management in Cilium

High Go

Severity: 7.5 / 10; High · CVSS 3.1
Exploit chance (EPSS): 0.36%; Chance of exploitation in the next 30 days. Higher than 30.39% of scored vulnerabilities.
Known exploited: No; Not in CISA's catalog
Weakness: CWE-269 Improper Privilege Management
Fix: 1.11.5; Upgrade github.com/cilium/cilium to this version or later

Description

Impact

If an attacker is able to perform a container escape of a container running as root on a host where Cilium is installed, the attacker can leverage Cilium's Kubernetes service account to gain access to cluster privileges that are more permissive than what is minimally required to operate Cilium. In affected releases, this service account had access to modify and delete Pod and Node resources.

Patches

The problem has been fixed and is available on versions >=1.9.16, >=1.10.11, >=1.11.5

Workarounds

There are no workarounds available.

Acknowledgements

The Cilium community has worked together with members of Isovalent, Amazon and Palo Alto Networks to prepare these mitigations. Special thanks to Micah Hausler (AWS), Robert Clark (AWS), Yuval Avrahami (Palo Alto Networks), and Shaul Ben Hai (Palo Alto Networks) for their cooperation.

github.com/cilium/cilium	`>= 1.10.0, < 1.10.11`	`1.10.11`

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

github.com/cilium/cilium Go → `1.11.5`

go get github.com/cilium/cilium@v1.11.5 && go mod tidy

Weakness

CWE-269: Improper Privilege Management

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

How to prevent it

Architecture and Design, Operation: Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Architecture and Design: Follow the principle of least privilege when assigning access rights to entities in a software system.
Architecture and Design: Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
