CyberRota Analysis
AI-GeneratedUnrealIRCd versions 6.0.5 through 6.2.6 are vulnerable due to a lack of limitation on the number of HTTP request headers, which can be exploited by remote attackers to trigger a denial of service, leading to memory exhaustion and server unresponsiveness. This vulnerability is particularly concerning for systems with websocket or JSON-RPC listeners enabled. Administrators of affected versions should prioritize applying the patch available in version 6.2.7 to mitigate this risk.
Original NVD Description
The webserver in UnrealIRCd 6.0.5 through 6.2.6 before 6.2.7 does not limit the number of HTTP request headers, which allows remote attackers to cause a denial of service (memory consumption and unresponsive server) via an HTTP request with an unlimited number of headers, if a websocket or JSON-RPC listener is enabled (disabled by default).
