CVE-2013-4322 describes a denial-of-service vulnerability in Apache Tomcat versions prior to 6.0.39, 7.0.50, and 8.0.0-RC10. This flaw allows remote attackers to disrupt service by sending malformed chunked transfer encoded data, specifically by exploiting improper handling of large data volumes or whitespace in HTTP trailer fields. The vulnerability has a CVSS score of 4.3 (medium severity), indicating a network-based attack with medium complexity and a potential impact of partial availability loss. Its EPSS score of 0.59364 is notably high, suggesting a higher-than-average likelihood of exploitation despite the medium CVSS. Currently, there is no known active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal, which is typical for the majority of vulnerabilities.
