⚠️ Risk & Real-World Impact
Worst Case
An attacker could gain administrative access to Junos Space, potentially compromising the entire network management system, stealing credentials, or deploying additional malicious payloads.
Likely Case
Attackers would typically steal session cookies or credentials to gain unauthorized access, potentially leading to privilege escalation or data exfiltration.
If Mitigated
With proper input validation and output encoding, the attack would fail to execute malicious scripts, limiting impact to failed exploitation attempts.
🎯 Exploit Status
Requires attacker to create/modify a report and trick a user into viewing it. No authentication bypass needed if attacker has report creation/modification access.
