Juniper Networks has launched an emergency replace to deal with a most severity vulnerability that results in authentication bypass in Session Sensible Router (SSR), Session Sensible Conductor, and WAN Assurance Router merchandise.
The safety situation is tracked as CVE-2024-2973 and an attacker may exploit it to take full management of the system.
“An Authentication Bypass Utilizing an Alternate Path or Channel vulnerability in Juniper Networks Session Sensible Router or Conductor working with a redundant peer permits a network-based attacker to bypass authentication and take full management of the system,” reads the outline of the vulnerability.
“Solely Routers or Conductors which can be working in high-availability redundant configurations are affected by this vulnerability,” Juniper notes within the safety advisory.
Internet admins apply “Excessive-availability redundant configurations” the place service continuity is vital. This configuration is crucial to sustaining uninterrupted companies and rising resilience in opposition to unexpected, disruptive occasions.
This makes the weak configuration fairly widespread in mission-critical community infrastructure, together with in massive enterprise environments, information facilities, telecommunications, e-commerce, and authorities or public companies.
The product variations impacted by CVE-2024-2973 are:
Session Sensible Router & Conductor:
- All variations earlier than 5.6.15
- From 6.0 earlier than 6.1.9-lts
- From 6.2 earlier than 6.2.5-sts
WAN Assurance Router:
- 6.0 variations earlier than 6.1.9-lts
- 6.2 variations earlier than 6.2.5-sts
Safety updates have been made accessible for Session Sensible Router in variations 5.6.15, 6.1.9-lts, and 6.2.5-sts.
