Networking and cybersecurity solutions provider Juniper Networks this week released more than 40 security advisories to describe over 70 vulnerabilities that affect the company’s products.
Roughly half of the advisories describe critical and high-severity vulnerabilities, including ones that can be exploited for denial-of-service (DoS) attacks, remote code execution (including through XSS attacks), privilege escalation, and security bypass. Many of the flaws are introduced by the use of third-party components.
A majority of the security holes impact Juniper’s Junos OS operating system, which powers many of the company’s products.
Overall critical severity ratings have been assigned to two advisories. One of them addresses over a dozen vulnerabilities discovered since 2017 in third-party components used by Contrail Insights (formerly known as AppFormix).
The second critical advisory describes an authentication bypass vulnerability affecting 128 Technology Session Smart Routers. The flaw can be exploited by an attacker to “view internal files, change settings, manipulate services and execute arbitrary code.”
Juniper has released updates and hotfixes to address the vulnerabilities disclosed this week and, in some cases, workarounds and mitigations are also available to prevent or reduce the risk of exploitation.
Juniper said many of the vulnerabilities were found during internal product security testing or research. There is no indication that any of these flaws has been exploited in the wild.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday instructed organizations to review the advisories from Juniper and apply the necessary updates.
