CVE-2022-34558
CRITICALCVE-2022-34558 is a critical-severity (CVSS 9.8) remote code execution vulnerability in global-workqueue_project global-workqueue. 1 public exploit reference exists, so weaponization risk is real. O3 Security detects and blocks CVE-2022-34558 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.
WMAgent v1.3.3rc2 and 1.3.3rc1, reqmgr 2 1.4.1rc5 and 1.4.0rc2, reqmon 1.4.1rc5, and global-workqueue 1.4.1rc5 allows attackers to execute arbitrary code via a crafted dbs-client package.
Description
WMAgent v1.3.3rc2 and 1.3.3rc1, reqmgr 2 1.4.1rc5 and 1.4.0rc2, reqmon 1.4.1rc5, and global-workqueue 1.4.1rc5 allows attackers to execute arbitrary code via a crafted dbs-client package.

Detection & mitigation playbook
Vendor / applianceDetect
Inventory every global-workqueue_project global-workqueue 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 remote code execution 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-2022-34558 yet — track the global-workqueue_project global-workqueue 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-2022-34558 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-2022-34558. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
