Cross-site scripting in Silverpeas Core 6.4.6 exposes other authenticated users to session hijacking or credential theft via the document management file upload feature. The scope-changed CVSS vector (S:C) confirms the injected script executes in a different security context than the upload origin, enabling impact beyond the uploading user's own session. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must be able to access the document management file upload feature - it is unclear from the description whether this endpoint requires authentication; the provided CVSS vector specifies PR:N (no privileges required), suggesting the upload endpoint may be accessible without authentication, though this is atypical for document management systems and not independently confirmed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS medium score of 6.1 reflects the limited confidentiality and integrity impact (C:L/I:L) and the user-interaction requirement (UI:R). … 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 | No vendor-released patch or fixed version has been identified at the time of analysis; the only available reference is a third-party researcher blog post. … Detailed patch versions, workarounds, and compensating controls in full report. |
