CVE-2022-45388
HIGHCVE-2022-45388 is a high-severity (CVSS 7.5) Path Traversal vulnerability in jenkins config rotator. O3 Security detects and blocks CVE-2022-45388 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.

Description
Jenkins Config Rotator Plugin 2.0.1 and earlier does not restrict a file name query parameter in an HTTP endpoint, allowing unauthenticated attackers to read arbitrary files with '.xml' extension on the Jenkins controller file system.
Affected Products
config rotatorjenkinsDetection & mitigation playbook
Vendor / applianceDetect
Inventory every jenkins config rotator 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-2022-45388 yet — track the jenkins config rotator 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-2022-45388 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-2022-45388. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
