How severe is CVE-2015-1778?

CVE-2015-1778 has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

How do I fix CVE-2015-1778?

Update org.opendaylight.odlparent:opendaylight-karaf-resources to 0.2.3-Helium-SR3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2015-1778 is resolved across your whole dependency graph.

How do I detect CVE-2015-1778 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.opendaylight.odlparent:opendaylight-karaf-resources, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2015-1778 if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is CVE-2015-1778 actively exploited in the wild?

No public exploit code has been indexed for CVE-2015-1778 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-2015-1778?

CVE-2015-1778 has an EPSS (Exploit Prediction Scoring System) score of 2.7%, placing it in the 86th 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. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.
