The first round of security advisories published by Juniper Networks for 2023 cover hundreds of vulnerabilities that have been patched in the networking giant’s products.
The 32 Juniper Networks security advisories published by the company this week cover more than 230 vulnerabilities, roughly 200 of which impact third-party components.
Three advisories have an overall severity rating of critical and they all describe vulnerabilities affecting third-party components. Twenty advisories have a ‘high severity’ rating and nine have a ‘medium severity’ rating.
Roughly two dozen Junos OS vulnerabilities have been patched by the company. All of them can be leveraged for denial-of-service (DoS) attacks, and a majority can be exploited by unauthenticated attackers who have network access to the targeted device.
There is no indication that any of these vulnerabilities has been exploited in the wild.
The US Cybersecurity and Infrastructure Security Agency (CISA) has advised organizations to review Juniper’s advisories and take action as necessary.
