F5 BIG-IP | Breaking Cybersecurity News | The Hacker News

F5 is warning of active abuse of a critical security flaw in BIG-IP less than a week after its public disclosure, resulting in the execution of arbitrary system commands as part of an exploit chain. Tracked as  CVE-2023-46747  (CVSS score: 9.8), the  vulnerability  allows an unauthenticated attacker with network access to the BIG-IP system through the management port to achieve code execution. A proof-of-concept (PoC)  exploit  has since been made  available  by ProjectDiscovery. It impacts the following versions of the software - 17.1.0 (Fixed in 17.1.0.3 + Hotfix-BIGIP-17.1.0.3.0.75.4-ENG) 16.1.0 - 16.1.4 (Fixed in 16.1.4.1 + Hotfix-BIGIP-16.1.4.1.0.50.5-ENG) 15.1.0 - 15.1.10 (Fixed in 15.1.10.2 + Hotfix-BIGIP-15.1.10.2.0.44.2-ENG) 14.1.0 - 14.1.5 (Fixed in 14.1.5.6 + Hotfix-BIGIP-14.1.5.6.0.10.6-ENG) 13.1.0 - 13.1.5 (Fixed in 13.1.5.1 + Hotfix-BIGIP-13.1.5.1.0.20.2-ENG) Now the company is  alerting  that it has "observed th...

F5 has warned of a high-severity flaw impacting BIG-IP appliances that could lead to denial-of-service (DoS) or arbitrary code execution. The issue is rooted in the iControl Simple Object Access Protocol ( SOAP ) interface and affects the following versions of BIG-IP - 13.1.5 14.1.4.6 - 14.1.5 15.1.5.1 - 15.1.8 16.1.2.2 - 16.1.3, and 17.0.0 "A format string vulnerability exists in iControl SOAP that allows an authenticated attacker to crash the iControl SOAP CGI process or, potentially execute arbitrary code," the company  said  in an advisory. "In appliance mode BIG-IP, a successful exploit of this vulnerability can allow the attacker to cross a security boundary." Tracked as CVE-2023-22374 (CVSS score: 7.5/8.5), security researcher Ron Bowes of Rapid7 has been credited with discovering and reporting the flaw on December 6, 2022. Given that the iCOntrol SOAP interface runs as root, a successful exploit could permit a threat actor to remotely trigger co...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Multiple security vulnerabilities have been disclosed in F5 BIG-IP and BIG-IQ devices that, if successfully exploited, to completely compromise affected systems. Cybersecurity firm Rapid7 said the  flaws  could be abused to remote access to the devices and defeat security constraints. The issues impact BIG-IP versions 13.x, 14.x, 15.x, 16.x, and 17.x, and BIG-IQ Centralized Management versions 7.x and 8.x. The two high-severity issues, which were reported to F5 on August 18, 2022, are as follows - CVE-2022-41622  (CVSS score: 8.8) - A cross-site request forgery ( CSRF ) vulnerability through iControl SOAP, leading to unauthenticated remote code execution. CVE-2022-41800  (CVSS score: 8.7) - An iControl REST vulnerability that could allow an authenticated user with an Administrator role to bypass  Appliance mode  restrictions. "By successfully exploiting the worst of the vulnerabilities (CVE-2022-41622), an attacker could gain persistent root access...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has  added  the recently disclosed F5 BIG-IP flaw to its  Known Exploited Vulnerabilities Catalog  following reports of  active abuse  in the wild. The flaw, assigned the identifier  CVE-2022-1388  (CVSS score: 9.8), concerns a  critical bug  in the BIG-IP iControl REST endpoint that provides an unauthenticated adversary with a method to execute arbitrary system commands. "An attacker can use this vulnerability to do just about anything they want to on the vulnerable server," Horizon3.ai  said  in a report. "This includes making configuration changes, stealing sensitive information and moving laterally within the target network." Patches and mitigations for the flaw were announced by F5 on May 4, but it has been  subjected  to  in-the-wild   exploitation  over the past week, with attackers attempting to install a web shell that grants...

Days after F5 released patches for a critical remote code execution vulnerability affecting its BIG-IP family of products, security researchers are warning that they were able to create an exploit for the shortcoming. Tracked  CVE-2022-1388  (CVSS score: 9.8), the flaw relates to an iControl REST authentication bypass that, if successfully exploited, could lead to remote code execution, allowing an attacker to gain initial access and take control of an affected system. This could range anywhere from deploying cryptocurrency miners to dropping web shells for follow-on attacks, such as information theft and ransomware. "We have reproduced the fresh CVE-2022-1388 in F5's BIG-IP," cybersecurity company Positive Technologies  said  in a tweet on Friday. "Patch ASAP!" The critical security vulnerability impacts the following versions of BIG-IP products - 16.1.0 - 16.1.2 15.1.0 - 15.1.5 14.1.0 - 14.1.4 13.1.0 - 13.1.4 12.1.0 - 12.1.6 11.6.1 - 11.6.5 Fixe...

Cybersecurity researchers on Wednesday disclosed a new bypass vulnerability (CVE-2021-23008) in the Kerberos Key Distribution Center (KDC) security feature impacting F5 Big-IP application delivery services. "The KDC Spoofing vulnerability allows an attacker to bypass the Kerberos authentication to Big-IP Access Policy Manager (APM), bypass security policies and gain unfettered access to sensitive workloads," Silverfort researchers Yaron Kassner and Rotem Zach said in a report. "In some cases this can be used to bypass authentication to the Big-IP admin console as well." Coinciding with the public disclosure, F5 Networks has released patches to address the weakness (CVE-2021-23008, CVSS score 8.1), with fixes introduced in BIG-IP APM versions 12.1.6, 13.1.4, 14.1.4, and 15.1.3. A similar patch for version 16.x is expected at a future date. "We recommend customers running 16.x check the security advisory to assess their exposure and get details on mitigati...

Application security company F5 Networks on Wednesday published an  advisory  warning of four critical vulnerabilities impacting multiple products that could result in a denial of service (DoS) attack and even unauthenticated remote code execution on target networks. The patches concern a total of seven related flaws (from CVE-2021-22986 through CVE-2021-22992),  two  of  which  were discovered and reported by Felix Wilhelm of Google Project Zero in December 2020. The four critical flaws affect BIG-IP versions 11.6 or 12.x and newer, with a critical pre-auth remote code execution (CVE-2021-22986) also affecting BIG-IQ versions 6.x and 7.x. F5 said it's not aware of any public exploitation of these issues. Successful exploitation of these vulnerabilities could lead to a full compromise of vulnerable systems, including the possibility of remote code execution as well as trigger a buffer overflow, leading to a DoS attack. Urging customers to update their...
