OpenAM Authenticated RCE via Groovy Sandbox Escape

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.48% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: OpenIdentityPlatform OpenAM 16.1.1.

Low priority for now. Upgrade to OpenIdentityPlatform OpenAM 16.1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, GroovySandboxValueFilter permits an authenticated server-side script author to escape the scripting sandbox despite the default class allow and deny lists. A user such as a sub-realm RealmAdmin who can create or edit a script in an executed context can invoke operating-system commands as the OpenAM application server account, crossing the realm-scoped administration boundary and compromising the JVM and every realm it serves. This issue is fixed in version 16.1.1.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.
