Juniper Networks last week published 21 security advisories to inform customers about more than 200 vulnerabilities affecting its products.
The security holes impact Junos OS (including on SRX, EX, PTX, QFX and MX series devices), Junos Space, Contrail Networking, and Northstar Controller products.
Six advisories describe six high-severity vulnerabilities that are specific to Juniper products. All except one of these vulnerabilities can be exploited by an unauthenticated attacker on the network to cause a denial of service (DoS) condition.
The remaining flaw can allow a local attacker authenticated with low privileges to take full control of the targeted device.
There are also six advisories with an overall rating of “critical” or “high severity” that describe more than 200 issues affecting third-party components such as Nginx, OpenSSL, Samba, Java SE, SQLite and Linux. While some of these flaws are relatively recent, others date back nearly a decade.
The remaining advisories describe medium-severity issues affecting Junos OS.
Juniper says it’s not aware of any attacks exploiting these vulnerabilities.
The US Cybersecurity and Infrastructure Security Agency (CISA) has advised organizations to review Juniper’s advisories and apply patches or mitigations as necessary.
