Spring Boot Admins integrated notifier support allows arbitrary code execution

High severity GitHub Reviewed Published Dec 9, 2022 in codecentric/spring-boot-admin • Updated Feb 2, 2023

Package

maven de.codecentric:spring-boot-admin (Maven)

Affected versions

< 2.6.10
>= 2.7.0, < 2.7.8
>= 3.0.0-M1, < 3.0.0-M6

Patched versions

2.6.10

Description

Impact

All users who run Spring Boot Admin Server, having enabled Notifiers (e.g. Teams-Notifier) and write access to environment variables via UI are possibly affected.

Patches

In the most recent releases of Spring Boot Admin 2.6.10 and 2.7.8 the issue is fixed by implementing SimpleExecutionContext of SpEL. This prevents the arbitrary code execution (i.e. SpEL injection).

Workarounds

  • Disable any notifier
  • Disable write access (POST request) on /env actuator endpoint

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
