CVE-2007-4556
opensymphony xwork: no CVSS score yet. EPSS 26% chance of exploitation in the next 30 days. Fixed in opensymphony:xwork 1.2.3, 2.0.4.
Struts support in OpenSymphony XWork before 1.2.3, and 2.x before 2.0.4, as used in WebWork and Apache Struts, recursively evaluates all input as an Object-Graph Navigation Language (OGNL) expression when altSyntax is enabled, which allows remote attackers to cause a denial of service (infinite loop) or execute arbitrary code via form input beginning with a "%{" sequence and ending with a "}" character.
