How do I patch CVE-2022-44877?

Apply the control-webpanel webpanel security patch or hotfix for CVE-2022-44877 on the affected version, following the vendor advisory for your exact build.

How do I detect CVE-2022-44877 across my infrastructure?

Inventory every control-webpanel webpanel deployment and check each version against the affected-products list above.

How do I mitigate CVE-2022-44877 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.

Is CVE-2022-44877 actively exploited in the wild?

Yes. There are 19 known exploit references for CVE-2022-44877, including 2 documented proof-of-concept exploits on Exploit-DB and 13 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2022-44877?

CVE-2022-44877 has an EPSS (Exploit Prediction Scoring System) score of 100.0%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2022-44877 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2022-44877 (CWP Control Web Panel OS Command Injection Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2023-01-17. CISA required all US federal civilian agencies to remediate this vulnerability by 2023-02-07. The required action was: Apply updates per vendor instructions. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2022-44877?

CVE-2022-44877 is classified as OS Command Injection (CWE-78). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Which products and versions are affected by CVE-2022-44877?

CVE-2022-44877 affects control-webpanel webpanel. Check the affected-products list on this page against your deployed version to confirm exposure.

Is there exploit tooling available for CVE-2022-44877?

A Nuclei detection template exists for CVE-2022-44877, meaning automated scanners can fingerprint it. A Metasploit module references CVE-2022-44877, which lowers the barrier to weaponization. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2022-44877 published, and has it been updated?

CVE-2022-44877 was published on January 5, 2023 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Exploitation Status

Actively exploited in the wild

Confirmed by CISA's Known Exploited Vulnerabilities catalog on 2023-01-17. Federal agencies were required to remediate by 2023-02-07.
CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
A successful exploit gives an attacker total control of the affected component, not partial access.
