CVE-2024-2973: Session Smart Router(SSR): On redundant router deployments API authentication can be bypassed
Noroxi assessment
Priority: Plan (action score 40/100)
- 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% (FIRST EPSS); higher than 65.3% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: Juniper Networks Session Smart Conductor 5.6.15, 6.1.9-lts, 6.2.5-sts; Juniper Networks Session Smart Router 5.6.15, 6.1.9-lts, 6.2.5-sts; Juniper Networks WAN Assurance Router 6.1.9-lts, 6.2.5-sts.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Add it to your regular patch cycle. Upgrade to Juniper Networks Session Smart Conductor 5.6.15, 6.1.9-lts, 6.2.5-sts; Juniper Networks Session Smart Router 5.6.15, 6.1.9-lts, 6.2.5-sts; Juniper Networks WAN Assurance Router 6.1.9-lts, 6.2.5-sts or later.

Primary sources: NVD · CVE.org · FIRST EPSS
An Authentication Bypass Using an Alternate Path or Channel vulnerability in Juniper Networks Session Smart Router or conductor running with a redundant peer allows a network based attacker to bypass authentication and take full control of the device. Only routers or conductors that are running in high-availability redundant configurations are affected by this vulnerability. No other Juniper Networks products or platforms are affected by this issue. This issue affects: Session Smart Router: * All versions before 5.6.15, * from 6.0 before 6.1.9-lts, * from 6.2 before 6.2.5-sts. Session Smart Conductor: * All versions before 5.6.15, * from 6.0 before 6.1.9-lts, * from 6.2 before 6.2.5-sts. WAN Assurance Router: * 6.0 versions before 6.1.9-lts, * 6.2 versions before 6.2.5-sts.
