How do I detect CVE-2017-0148 across my infrastructure?

Inventory every microsoft server message block deployment and check each version against the affected-products list above.

How do I mitigate CVE-2017-0148 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.

Is CVE-2017-0148 actively exploited in the wild?

Yes. There are 15 known exploit references for CVE-2017-0148, including 3 documented proof-of-concept exploits on Exploit-DB and 11 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-2017-0148?

CVE-2017-0148 has an EPSS (Exploit Prediction Scoring System) score of 99.4%, 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-2017-0148 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2017-0148 (Microsoft SMBv1 Server Remote Code Execution Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2022-04-06. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-04-27. The required action was: Apply updates per vendor instructions. This CVE has been used in known ransomware campaigns. 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-2017-0148?

CVE-2017-0148 is classified as Improper Input Validation (CWE-20). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.
