Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated Nexus Repository 3 session with an account explicitly granted the nexus:capabilities:read privilege; accounts without this specific privilege cannot access the capability read API. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.0 (Medium) with vector AV:N/AC:L/AT:P/PR:L/UI:N/VC:H correctly captures the attack profile: network-reachable, low-complexity, but gated behind a specific authenticated privilege (nexus:capabilities:read) rather than being fully unauthenticated. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The primary remediation is upgrading Nexus Repository 3 to version 3.96.0 or later, as confirmed by Sonatype's release notes (https://help.sonatype.com/en/sonatype-nexus-repository-3-96-0-release-notes.html) and support advisory (https://support.sonatype.com/hc/en-us/articles/54639904174099/). … Detailed patch versions, workarounds, and compensating controls in full report. |
