Vulnerability AssessmentAI
| Exploitation | Exploitation requires two concrete prerequisites: first, the attacker must hold a valid low-privileged account on the target AEM instance (confirmed by PR:L in the CVSS vector); second, a victim with an active higher-privilege AEM session must actively open a crafted URL (confirmed by UI:R). … Additional conditions and limiting factors are described in the full assessment. |
