CVE-2022-3146
MEDIUMCVE-2022-3146 is a medium-severity (CVSS 5.5) Path Traversal vulnerability in openstack tripleo ansible. O3 Security detects and blocks CVE-2022-3146 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.

Description
A flaw was found in tripleo-ansible. Due to an insecure default configuration, the permissions of a sensitive file are not sufficiently restricted. This flaw allows a local attacker to use brute force to explore the relevant directory and discover the file. This issue leads to information disclosure of important configuration details from the OpenStack deployment.

Vendor / applianceDetect
Inventory every openstack tripleo ansible 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-2022-3146 yet — track the openstack tripleo ansible 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-2022-3146 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-2022-3146. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
