CyberRota Analysis
AI-GeneratedOpenResty versions from 1.29.2.1 to before 1.29.2.5 are vulnerable to an out-of-bounds write in the PROXY protocol v2 implementation, which can lead to worker process crashes and denial of service when configured to send PROXY protocol v2 headers. Organizations using OpenResty with PROXY protocol v2 enabled for upstream connections should prioritize upgrading to version 1.29.2.5 to mitigate this high-severity vulnerability.

Original NVD Description
OpenResty is a high performance web platform. From 1.29.2.1 to before 1.29.2.5, an out-of-bounds write vulnerability exists in the upstream PROXY protocol v2 implementation. When OpenResty is configured to send PROXY protocol version 2 headers to upstream servers, constructing the header in the stream proxy protocol v2 patch can write beyond the bounds of the allocated buffer, causing the worker process to crash and resulting in a denial of service. Only configurations that explicitly enable PROXY protocol v2 for upstream connections are impacted. This issue is fixed in version 1.29.2.5.
