CVE-2013-4310 describes an access control bypass vulnerability affecting Apache Struts versions 2.0.0 through 2.3.15.1, allowing remote attackers to circumvent security measures using a specially crafted "action:" prefix. With a CVSS score of 5.8, this medium-severity flaw has a network attack vector, medium attack complexity, and could lead to partial confidentiality and integrity impacts. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, its EPSS score suggests a higher than average likelihood of exploitation compared to many other CVEs.
