Session Smart Router(SSR): On redundant router deployments API authentication can be bypassed

03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
  • Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
1.08% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 65.1% of scored records. A rank, not a probability.
NVD base score
10.0 (CVSS v4.0), scored by the NVD independently of the CNA.

Red Hat severity
No Red Hat rating. Red Hat rates the CVEs that affect its products.

Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.

07 Remediation

The following software releases have been updated to resolve this issue: Session Smart Router: SSR-5.6.15, SSR-6.1.9-lts, SSR-6.2.5-sts, and subsequent releases. It is suggested to upgrade all affected systems to these versions of software. In a Conductor-managed deployment, it is sufficient to upgrade the Conductor nodes only and the fix will be applied automatically to all connected routers. As practical, the routers should still be upgraded to a fixed version however they will not be vulnerable once they connect to an upgraded Conductor. This vulnerability has been patched automatically on affected devices for WAN Assurance routers connected to the Mist Cloud. For systems that are provisioned in a High-Availability cluster, these should be upgraded to a patched version as soon as practical (SSR-6.1.9 or SSR-6.2.5). It is important to note that the fix is applied automatically on managed routers by a Conductor or on WAN assurance routers has no impact on data-plane functions of the router. The application of the fix is non-disruptive to production traffic. There may be a momentary downtime (less than 30 seconds) to the web-based management and APIs however this will resolve quickly.
