"Remote Code Execution Vulnerabilities Found in F5 Products"

Security researchers at cybersecurity firm Rapid7 have identified several vulnerabilities and other potential security issues affecting F5 products.  The researchers reported their findings to the vendor in mid-August and disclosed details on Wednesday, just as F5 released advisories to inform customers about the security holes and the availability of engineering hotfixes.  Two of the issues discovered by the researchers have been described as high-severity remote code execution vulnerabilities and assigned CVE identifiers, while the rest are security bypass methods that F5 does not view as vulnerabilities.  The most serious vulnerability is CVE-2022-41622, a cross-site request forgery (CSRF) issue affecting BIG-IP and BIG-IQ products.  The researchers noted that exploitation can allow a remote, unauthenticated attacker to gain root access to a device’s management interface, even if the interface is not exposed to the internet.  However, exploitation requires the attacker to have some knowledge of the targeted network, and they need to convince a logged-in administrator to visit a malicious website that is set up to exploit CVE-2022-41622.  The researchers stated that if exploited, the vulnerability can compromise the complete system.  The second vulnerability, CVE-2022-41800, allows an attacker with admin privileges to execute arbitrary shell commands via RPM specification files.  The researchers also identified several other security issues, including a local privilege escalation via bad Unix socket permissions and two SELinux bypass methods.  The researchers believe that the widespread exploitation of these vulnerabilities is unlikely.  However, the researchers stated that F5 customers should probably not ignore them, considering that BIG-IP appliances have been known to be targeted by threat actors.
