CVE-2024-49214 [MEDIUM] CWE-940 haproxy: Spoofed IP Bypass in HAProxy QUIC Listener 0-RTT Sessions
haproxy: Spoofed IP Bypass in HAProxy QUIC Listener 0-RTT Sessions
QUIC in HAProxy 3.1.x before 3.1-dev7, 3.0.x before 3.0.5, and 2.9.x before 2.9.11 allows opening a 0-RTT session with a spoofed IP address. This can bypass the IP allow/block list functionality.
A flaw was found in HAProxy's QUIC listener. This vulnerability can allow an attacker to bypass the IP allow/block list via a spoofed IP address in a 0-RTT session. The attacker could exploit this by obtaining a TLS session ticket using their real IP, then initiating a 0-RTT session with a spoofed IP address, allowing them to send HTTP/3 requests.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE
