OpenAI's agent chained decade-old DoS attacks to crash web servers in seconds
Summary
Researchers have demonstrated how OpenAI's Codex can chain together a decade-old HTTP/2 denial-of-service (DoS) vulnerability, the "HTTP/2 Rapid Reset" attack, to crash web servers in seconds. This showcases how AI can be leveraged to quickly identify and exploit known vulnerabilities, posing a significant threat to web infrastructure.
IFF Assessment
This article highlights how AI can be used to automate and accelerate the exploitation of known vulnerabilities, increasing the threat landscape for defenders.
Severity
The HTTP/2 Rapid Reset attack (CVE-2023-44487) is a powerful amplification attack that leverages the HTTP/2 protocol's stream reset feature. This vulnerability allows for a very high impact, with minimal complexity and widespread applicability to any server supporting HTTP/2, leading to a high CVSS score.
CISA KEV: Listed as actively exploited. Federal patch due: October 31, 2023. Known ransomware use: Unknown.
Defender Context
This research underscores the evolving threat of AI-powered attacks, where sophisticated AI models can rapidly discover and weaponize known vulnerabilities. Defenders must stay vigilant about patching systems, especially those supporting HTTP/2, and consider implementing advanced detection and mitigation strategies against such amplified DoS attacks.
