The F5 flaws could have an affect on the networking infrastructure for some of the premier tech and Fortune 500 corporations – together with Microsoft, Oracle and Facebook.
F5 Networks is warning end users to patch four critical remote command execution (RCE) flaws in its Big-IP and Massive-IQ organization networking infrastructure. If exploited, the flaws could allow for attackers to just take full regulate more than a susceptible process.
The enterprise released an advisory, Wednesday, on 7 bugs in overall, with two other individuals rated as significant risk and one rated as medium risk, respectively. “We strongly inspire all prospects to update their Massive-IP and Large-IQ methods to a set model as soon as attainable,” the organization advised on its web page.
The scenario is significantly urgent as F5 presents organization networking to some of the major tech organizations in the environment, which include Facebook, Microsoft and Oracle, as effectively as to a trove of Fortune 500 companies, which include some of the world’s biggest financial establishments and ISPs.
The U.S. Cybersecurity and Infrastructure Agency (CISA) also urged organizations applying Significant-IP and Massive-IQ to deal with two of the critical vulnerabilities, which are remaining tracked as CVE-2021-22986 and CVE-2021-22987.
The former, with a CVSS score of 9.8, is an unauthenticated remote command execution vulnerability in the iControl Relaxation interface, in accordance to a specific breakdown of the bugs in F5’s Know-how Center. The latter, with a CVSS rating of 9.9, impacts the infrastructure’s Traffic Administration Person Interface (TMUI), also referred to as the Configuration utility. When jogging in Appliance method, the TMUI has an authenticated RCE vulnerability in undisclosed web pages, according to F5.
The two other critically rated vulnerabilities are getting tracked as CVE-2021-22991 and CVE-2021-22992. The 1st, with a CVSS score of 9., is a buffer overflow vulnerability that can be brought on when “undisclosed requests to a digital server may well be incorrectly managed by the Site visitors Administration Microkernel (TMM) URI normalization,” according to F5. This can consequence in a denial-of-support (DoS) attack, that, in some scenarios, “may theoretically allow for bypass of URL based mostly obtain control or distant code execution (RCE),” the organization warned.
CVE-2021-22992 is also a buffer overflow bug with a CVSS rating of 9. This flaw can be activated by “a destructive HTTP reaction to an Superior WAF/Large-IP ASM virtual server with Login Page configured in its coverage,” in accordance to F5. It also may let for RCE and “complete method compromise” in some situations, the firm warned.
The other three non-critical bugs being patched in F5’s update this week are CVE-2021-22988, CVE-2021-22989 and CVE-2021-22990.
CVE-2021-22988, with a CVSS rating of 8.8, is an authenticated RCE that also impacts TMUI. CVE-2021-22989, with a CVSS rating of 8., is yet another authenticated RCE that also has an effect on TMUI in Appliance method, this time when Advanced WAF or Large-IP ASM are provisioned. And CVE-2021-2290, with a CVSS rating of 6.6, is a similar but a lot less unsafe vulnerability that exists in the same situation, in accordance to F5.
F5 is no stranger to critical bugs in its business networking products and solutions. In July, the seller and other security experts—including U.S. Cyber Command—urged corporations to deploy an urgent patch for a critical RCE vulnerability in Major-IP’s app supply controllers that was being actively exploited by attackers to scrape qualifications, launch malware and much more. That bug, (CVE-2020-5902), had a CVSS rating of 10 out of 10. Furthermore, a delay in patching at the time remaining programs uncovered to the flaw for weeks after F5 introduced the repair.
