Last modified
CVE-2023-50784 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. A buffer overflow in websockets in UnrealIRCd 6.1.0 through 6.1.3 before 6.1.4 allows an unauthenticated remote attacker to crash the server by sending an oversized packet (if a websocket port is open). Remote code execution might be possible on some uncommon, older platforms.. EPSS estimates a 1.91% chance of exploitation in the next 30 days.
