Buffer overflow in HAProxy 1.4 through 1.4.22 and 1.5-dev through 1.5-dev17, when HTTP keep-alive is enabled, using HTTP keywords in TCP inspection rules, and running with rewrite rules that appends to requests, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted pipelined HTTP requests that prevent request realignment from occurring.

Security readout for executives and security teams

This HAProxy flaw can let a remote client crash an affected proxy, and the CVE says arbitrary code execution may be possible. Exposure depends on a specific HAProxy configuration: HTTP keep-alive, HTTP keywords in TCP inspection rules, and request-appending rewrite rules. Likely limited to internet-facing or internal HAProxy deployments running the listed old versions with the specific keep-alive, TCP inspection, and rewrite-rule combination. Modern HAProxy versions or deployments without that configuration are less likely exposed. Treat as high priority for any legacy HAProxy estate, especially internet-facing gateways. The main business risk is proxy outage, with possible code execution noted but not fully evidenced in the supplied bundle. Mitigation focus: Identify HAProxy 1.4.x and 1.5-dev deployments in all environments.; Review configurations for keep-alive, HTTP TCP inspection keywords, and request-appending rewrite rules.; Apply HAProxy or operating-system vendor security updates from relevant advisories..
