Patch these Juniper Networks bugs, CISA says • The Register


Juniper Networks has patched essential-rated bugs across its Junos Space, Contrail Networking and NorthStar Controller merchandise that are severe plenty of to prompt CISA to weigh in and suggest admins to update the software as soon as doable.

“CISA encourages buyers and directors to assessment the Juniper Networks safety advisories webpage and utilize the essential updates,” in accordance to the Feds’ warning this 7 days.

Vital point listed here is evaluation: some of these flaws can be exploited to provide down equipment, or let a rogue non-admin insider to just take in excess of a box. Some might not be immediately exploitable but existing in application inside Juniper’s goods. So, critique the chance, and update appropriately.

We’ll commence with the security holes in Junos Room, the vendor’s community management computer software, which Juniper collectively rated “essential.” This is for the reason that, contrary to the important flaws detailed in three other stability bulletins released this week, we don’t know if these particular bugs are by now being exploited.

All of the other products’ crucial safety updates note that Juniper is not conscious of any destructive exploitation — but that discover is conspicuously absent from the Junos House flaws and the seller didn’t respond to The Sign up‘s inquiries about in-the-wild exploits.

According to the bulletin, which collectively rated 31 Junos Room bugs as important, the vulns affect numerous 3rd-occasion products and solutions which include nginx resolver, Oracle Java SE, OpenSSH, Samba, the RPM deal manager, Kerberos, OpenSSL, the Linux kernel, curl, and MySQL Server.

A person of these, tracked as CVE-2021-23017 in nginx resolver, obtained a CVSS severity score of 9.4 out of 10, and if exploited could allow an attacker to crash the total process. It “might allow an attacker who is ready to forge UDP packets from the DNS server to trigger one particular-byte memory overwrite, resulting in worker course of action crash or potential other effect,” Juniper warned.

The networking and security organization also issued an notify about important vulnerabilities in Junos House Security Director Coverage Enforcer — this piece provides centralized risk administration and checking for application-outlined networks — but famous that it really is not aware of any destructive exploitation of these critical bugs.

Although the vendor did not provide facts about the Coverage Enforcer bugs, they received a 9.8 CVSS rating, and there are “various” vulnerabilities in this item, according to the stability bulletin. The flaws influence all versions of Junos Space Coverage Enforcer prior to 22.1R1, and Juniper stated it has set the problems.

The subsequent group of critical vulnerabilities exist in third-bash application utilised in the Contrail Networking product. In this protection bulletin, Juniper issued updates to handle much more than 100 CVEs that go back again to 2013.

Upgrading to release 21.4. fixes the Open up Container Initiative-compliant Pink Hat Common Base Graphic container impression from Pink Hat Organization Linux 7 to Crimson Hat Business Linux 8, the seller stated in the notify.

And in its fourth crucial safety bulletin issued this 7 days, Juniper fixed a remote code execution bug, tracked as CVE-2021-23017, that affects its NorthStar Controller product or service and been given a 9.4 CVSS rating.

The vendor described it as an “off-by-one particular error vulnerability.” It’s in the nginx resolver, applied in Juniper’s NorthStar Controller item, and if exploited could let an unauthenticated, distant attacker that can forge UDP packets from the DNS server to again cause a a person-byte memory overwrite. This, in accordance to the firm, could result in crashing the system or arbitrary code execution. 

Upgrading nginx from 1.18. to 1.20.1 mounted this concern.

In addition to the 4 important stability updates, Juniper also this week issued 24 that it deemed “higher severity” for items together with Junos OS, Protected Analytics, Identification Administration Service, Paragon Energetic Assurance and Contrail Networking products traces. The Junos OS bug, for occasion, can be abused by a logged-in lower-level person to get whole command of the procedure, we observe (CVE-2022-22221). ®
