Attackers Can Weaponize Firewalls and Middleboxes for Amplified DDoS Attacks
2021-08-22 02:33

Weaknesses in the implementation of TCP protocol in middleboxes and censorship infrastructure could be weaponized as a vector to stage reflected denial of service amplification attacks, surpassing many of the existing UDP-based amplification factors to date. Detailed by a group of academics from the University of Maryland and the University of Colorado Boulder at the USENIX Security Symposium, the volumetric attacks take advantage of TCP-non-compliance in-network middleboxes - such as firewalls, intrusion prevention systems, and deep packet inspection boxes - to amplify network traffic, with hundreds of thousands of IP addresses offering amplification factors exceeding those from DNS, NTP, and Memcached.

Researchers find high-severity command injection vuln in Fortinet's web app firewall

Researchers have discovered a vulnerability in Fortinet's FortiWeb web application firewall, and while it has been classified as high severity, the actual risk of exploitation in the wild seems low. Tod Beardsley, director of research at Rapid7, told SecurityWeek that they have not seen any information from Fortinet regarding a patch, but they do expect the vulnerability to be fixed soon.

Weaknesses in the implementation of TCP protocol in middleboxes and censorship infrastructure could be weaponized as a vector to stage reflected denial of service amplification attacks against any target, surpassing many of the existing UDP-based amplification factors to date. The research, which received a Distinguished Paper Award at the conference, is the first of its kind to describe a technique to carry out DDoS reflected amplification attacks over the TCP protocol by abusing middlebox misconfigurations in the wild, a method previously deemed effective at preventing such spoofing attacks.
