Patch these Juniper Networks bugs, CISA says • The Register

Juniper Networks has patched vital-rated bugs throughout its Junos House, Contrail Networking and NorthStar Controller products that are serious plenty of to prompt CISA to weigh in and recommend admins to update the computer software as quickly as attainable.

“CISA encourages customers and directors to evaluation the Juniper Networks protection advisories website page and apply the necessary updates,” according to the Feds’ warning this week.

Key issue here is critique: some of these flaws can be exploited to deliver down products, or enable a rogue non-admin insider to consider in excess of a box. Some may perhaps not be immediately exploitable but current in computer software within Juniper’s merchandise. So, overview the danger, and update accordingly.

We are going to start with the protection holes in Junos Room, the vendor’s network administration program, which Juniper collectively rated “significant.” This is mainly because, in contrast to the significant flaws detailed in 3 other safety bulletins released this week, we do not know if these unique bugs are already staying exploited.

All of the other products’ crucial security updates observe that Juniper is not knowledgeable of any destructive exploitation — but that observe is conspicuously absent from the Junos Place flaws and the vendor failed to reply to The Sign-up‘s inquiries about in-the-wild exploits.

In accordance to the bulletin, which collectively rated 31 Junos Place bugs as vital, the vulns influence many third-party solutions which include nginx resolver, Oracle Java SE, OpenSSH, Samba, the RPM package deal supervisor, Kerberos, OpenSSL, the Linux kernel, curl, and MySQL Server.

One of these, tracked as CVE-2021-23017 in nginx resolver, been given a CVSS severity score of 9.4 out of 10, and if exploited could allow for an attacker to crash the entire procedure. It “may possibly allow for an attacker who is able to forge UDP packets from the DNS server to bring about a person-byte memory overwrite, ensuing in worker process crash or probable other impression,” Juniper warned.

The networking and stability business also issued an warn about important vulnerabilities in Junos Space Stability Director Plan Enforcer — this piece delivers centralized threat administration and checking for application-defined networks — but observed that it really is not mindful of any destructive exploitation of these vital bugs.

Though the seller did not present facts about the Coverage Enforcer bugs, they been given a 9.8 CVSS rating, and there are “a number of” vulnerabilities in this products, in accordance to the safety bulletin. The flaws impact all versions of Junos Space Coverage Enforcer prior to 22.1R1, and Juniper mentioned it has mounted the challenges.

The up coming group of significant vulnerabilities exist in third-bash software made use of in the Contrail Networking product. In this stability bulletin, Juniper issued updates to tackle far more than 100 CVEs that go back again to 2013.

Upgrading to release 21.4. fixes the Open up Container Initiative-compliant Pink Hat Universal Foundation Graphic container picture from Crimson Hat Enterprise Linux 7 to Purple Hat Enterprise Linux 8, the vendor described in the warn.

And in its fourth significant protection bulletin issued this 7 days, Juniper fastened a remote code execution bug, tracked as CVE-2021-23017, that has an effect on its NorthStar Controller products and obtained a 9.4 CVSS score.

The seller described it as an “off-by-1 mistake vulnerability.” It really is in the nginx resolver, used in Juniper’s NorthStar Controller products, and if exploited could make it possible for an unauthenticated, remote attacker that can forge UDP packets from the DNS server to again induce a one particular-byte memory overwrite. This, in accordance to the business, could consequence in crashing the procedure or arbitrary code execution. 

Upgrading nginx from 1.18. to 1.20.1 preset this situation.

In addition to the 4 crucial safety updates, Juniper also this week issued 24 that it considered “substantial severity” for solutions such as Junos OS, Safe Analytics, Identification Administration Service, Paragon Lively Assurance and Contrail Networking product traces. The Junos OS bug, for occasion, can be abused by a logged-in very low-amount user to get full regulate of the technique, we note (CVE-2022-22221). ®
