CVE-2023-24455
MEDIUMCVE-2023-24455 is a medium-severity (CVSS 4.3) Path Traversal vulnerability in jenkins visual expert. O3 Security detects and blocks CVE-2023-24455 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.

Description
Jenkins visualexpert Plugin 1.3 and earlier does not restrict the names of files in methods implementing form validation, allowing attackers with Item/Configure permission to check for the existence of an attacker-specified file path on the Jenkins controller file system.
Affected Products

Vendor / applianceDetect
Inventory every jenkins visual expert 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-2023-24455 yet — track the jenkins visual expert 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-2023-24455 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-2023-24455. 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-2023-24455 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2023-24455 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
