Critical patches released for significant F5 BIG-IP vulnerabilities

Soon after the release of patches for critical F5 BIG-IP vulnerability, Security researchers have introduced a POC of exploiting the vulnerability targeting users of BIG-IP devices, namely, governments, Fortune 500 firms, banks, Internet services providers, and brands, such as Microsoft, Oracle, and Facebook, indicating just how easy it is to infiltrate network security systems.

  • The 10/10 CVSSv3 rating vulnerability allows a remote attacker to gain full access to the system through Traffic Management User Interface (TMUI), export user credentials and potentially penetrate the device’s network, without the need for authentication.
  • In light of the severity of the vulnerability, users were advised by the US Cyber Command to install the security updates as soon as possible.

  • Over the last few days, security researchers published a number of PoC exploits to vulnerable F5 BIG-IP devices, to demonstrate the easiness of breaching a network using vulnerable devices.
  • It is highly recommended that all BIG-IP devices susceptible to these attacks, such as cloud marketplaces, update to the patched versions available by F5.
