CVE-2022-25350
HIGHCVE-2022-25350 is a high-severity (CVSS 7.4) OS Command Injection vulnerability in helecloud puppet-facter. 1 public exploit reference exists, so weaponization risk is real. O3 Security detects and blocks CVE-2022-25350 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.
All versions of the package puppet-facter are vulnerable to Command Injection via the getFact function due to improper input sanitization.
Description
All versions of the package puppet-facter are vulnerable to Command Injection via the getFact function due to improper input sanitization.

puppet-facterhelecloudResearch use only. For defensive security, authorized penetration testing, and academic research only. Never execute exploit code against systems without explicit written authorization.
Detection & mitigation playbook
Vendor / applianceDetect
Inventory every helecloud puppet-facter 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-2022-25350 yet — track the helecloud puppet-facter 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-2022-25350 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-2022-25350. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
