Remote Code Execution Vulnerabilities Found in F5 Products

Researchers at cybersecurity firm Rapid7 have identified several vulnerabilities and other potential security issues affecting F5 products.

Rapid7 reported its 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 Rapid7 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. 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.

“If exploited, the vulnerability can compromise the complete system,” F5 wrote in its advisory.

The second vulnerability, CVE-2022-41800, allows an attacker with admin privileges to execute arbitrary shell commands via RPM specification files.

In addition, the cybersecurity firm has identified several security issues, including a local privilege escalation via bad Unix socket permissions, and two SELinux bypass methods.

Rapid7 believes widespread exploitation of these vulnerabilities is unlikely. However, F5 customers should probably not ignore them considering that BIG-IP appliances have been known to be targeted by threat actors.
