Juniper Networks has moved quickly to address a significant security flaw in select routers through the release of out-of-band security updates. The flaw, identified as CVE-2024-2973 and given a CVSS severity score of 10.0, poses a critical risk due to its potential for authentication bypass.

The flaw allows a network-based attacker to sidestep authentication measures and gain complete control over the affected Juniper Networks Session Smart Routers or Conductors operating with a redundant peer setup. The impacted devices include Session Smart Routers and Conductors running specific versions before designated updates, as well as WAN Assurance Routers running specified versions.

Despite there being no recorded instances of active exploitation in the wild, Juniper Networks remains vigilant. The company uncovered the vulnerability during internal testing and confirms that automatic patches have been deployed for Mist managed WAN Assurance routers. These patches have no adverse impact on the routers' data-plane functions.

This proactive response by Juniper Networks demonstrates a commitment to cybersecurity, especially in light of previous critical vulnerabilities. With threat actors leveraging security flaws in different Juniper Networks products in recent years, users are encouraged to apply patches promptly to mitigate potential risks and safeguard their network infrastructure.
