CVE-2023-0229
MEDIUMCVE-2023-0229 is a medium-severity (CVSS 6.3) Improper Input Validation vulnerability in redhat openshift. O3 Security detects and blocks CVE-2023-0229 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.
A flaw was found in github.com/openshift/apiserver-library-go, used in OpenShift 4.12 and 4.11, that contains an issue that can allow low-privileged users to set the seccomp profile…
Description
A flaw was found in github.com/openshift/apiserver-library-go, used in OpenShift 4.12 and 4.11, that contains an issue that can allow low-privileged users to set the seccomp profile for pods they control to "unconfined." By default, the seccomp profile used in the restricted-v2 Security Context Constraint (SCC) is "runtime/default," allowing users to disable seccomp for pods they can create and modify.
Affected Products
openshiftredhatDetection & mitigation playbook
Vendor / applianceDetect
Inventory every redhat openshift deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Remediation status
No patch has shipped for CVE-2023-0229 yet — track the redhat openshift advisory for a fixed release and apply the workarounds below in the meantime.
Mitigate without a patch
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2023-0229 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2023-0229. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-0229 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2023-0229 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
