How severe is CVE-2025-64328?

No CVSS score has been assigned to CVE-2025-64328 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-64328?

Affected package information for CVE-2025-64328 is not yet fully mapped. Check the official advisory links for details.

How do I fix CVE-2025-64328?

Upgrade the affected component to the fixed release for CVE-2025-64328, or apply your distribution's backported patch — distro builds are often patched at an older version number, so check your vendor's advisory rather than the upstream version alone.

How do I detect CVE-2025-64328 in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate CVE-2025-64328 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.

Is CVE-2025-64328 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-64328 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-64328?

CVE-2025-64328 has an EPSS (Exploit Prediction Scoring System) score of 84.6%, 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-2025-64328 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2025-64328 (Sangoma FreePBX OS Command Injection Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2026-02-03. CISA required all US federal civilian agencies to remediate this vulnerability by 2026-02-24. The required action was: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. 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-2025-64328?

CVE-2025-64328 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.

Is there exploit tooling available for CVE-2025-64328?

A Nuclei detection template exists for CVE-2025-64328, meaning automated scanners can fingerprint it. 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-2025-64328 published, and has it been updated?

CVE-2025-64328 was published on November 7, 2025 and was last updated on October 21, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. In versions 17.0.2.36 and above before 17.0.3, the filestore module within the Administrative interface is vulnerable to a post-authentication command injection by an authenticated known user via the testconnection -> check_ssh_connect() function. An attacker can leverage this vulnerability to obtain remote access to the system as an asterisk user. This issue is fixed in version 17.0.3.
