HIGHAnt Media Server vulnerable to local privilege escalation
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Ant Media Server is live streaming engine software. A local privilege escalation vulnerability in present in versions 2.6.0 through 2.8.2 allows any unprivileged operating system user account to escalate privileges to the root user account on the system. This vulnerability arises from Ant Media Server running with Java Management Extensions (JMX) enabled and authentication disabled on localhost on port 5599/TCP. This vulnerability is nearly identical to the local privilege escalation vulnerability CVE-2023-26269 identified in Apache James. Any unprivileged operating system user can connect to the JMX service running on port 5599/TCP on localhost and leverage the MLet Bean within JMX to load a remote MBean from an attacker-controlled server. This allows an attacker to execute arbitrary code within the Java process run by Ant Media Server and execute code within the context of the antmedia service account on the system. Version 2.9.0 contains a patch for the issue. As a workaround, one may remove certain parameters from the antmedia.service file.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.antmedia:ant-media-server. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update io.antmedia:ant-media-server to 2.9.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-32656 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2024-32656 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2024-32656. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
