Cisco Umbrella Dashboard Session Management Vulnerability
Noroxi assessment
Priority: Monitor (action score 35/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 1.4% (FIRST EPSS); higher than 73.7% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS
A vulnerability in the session management functionality of the web UI for the Cisco Umbrella Dashboard could allow an authenticated, remote attacker to access the Dashboard via an active, user session. The vulnerability exists due to the affected application not invalidating an existing session when a user authenticates to the application and changes the users credentials via another authenticated session. An attacker could exploit this vulnerability by using a separate, authenticated, active session to connect to the application through the web UI. A successful exploit could allow the attacker to maintain access to the dashboard via an authenticated user's browser session. Cisco has addressed this vulnerability in the Cisco Umbrella Dashboard. No user action is required.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
