Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: CVE-2024-7387 is a critical **Path Traversal** flaw in Red Hat OpenShift's Docker build strategy.β¦
π’ **Affected**: **Red Hat OpenShift Container Platform 4**. Specifically, the component `openshift/builder` is vulnerable. Any cluster running this version with the Docker build strategy enabled is at risk.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: 1. **Privilege Escalation**: Move from **Developer** role to **Root** on the node. 2. **Cluster Compromise**: Extract **kubelet certificates** to control the entire cluster. 3.β¦
π£ **Public Exploits**: **YES**. Multiple PoCs are available on GitHub (e.g., `0xSigSegv0x00`, `fatcatresearch`). They demonstrate how to overwrite system binaries for privilege escalation.β¦
π **Self-Check**: 1. Check if you are running **OpenShift 4**. 2. Verify if the **Docker build strategy** is enabled. 3. Scan for unauthorized **symlinks** in build contexts pointing to `/usr/bin`. 4.β¦
β **Official Fix**: **YES**. Red Hat has released security advisories **RHSA-2024:6691** and **RHSA-2024:6705**. The fix is included in the latest updates for OpenShift Container Platform 4.β¦
π **No Patch Workaround**: 1. **Disable Docker Build Strategy**: If not needed, disable it to remove the attack vector. 2. **Restrict Permissions**: Ensure developers cannot mount secrets to arbitrary paths. 3.β¦
β‘ **Urgency**: **CRITICAL**. CVSS Score is **9.8** (Critical). Although it requires initial cluster access, the impact is full cluster compromise. **Patch immediately** upon applying the Red Hat update.β¦
