CyberRota Analysis
AI-GeneratedThe FTP parser in Suricata versions 8.0.5 to 8.0.6 is vulnerable to a denial-of-service condition due to improper handling of oversized transaction lists, which can lead to degraded packet processing and reduced monitoring visibility. Attackers can exploit this vulnerability by sending specially crafted FTP traffic, potentially impacting network security operations. Organizations using affected versions of Suricata should prioritize upgrading to version 8.0.6 or later to mitigate this risk.

Original NVD Description
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.5 until 8.0.6, the FTP parser in src/app-layer-ftp.c can continue allocating transactions after app-layer.protocols.ftp.max-tx is reached while processing one large chunk of FTP command data. The oversized transaction list is repeatedly processed with quadratic complexity after the too_many_transactions event, allowing crafted FTP traffic to degrade packet processing, reduce monitoring visibility, or cause denial of service. This issue is fixed in version 8.0.6.
