Remote Code Execution

struts2-core is vulnerable to remote code execution. Tag attributes can be used to perform a double evaluation when forced OGNL evaluation is applied, by using the %... syntax. This can lead to remote code execution when an attacker provides a malicious input to be evaluated...

Denial Of Service (DoS)

struts2-core is vulnerable to denial of service DoS. The vulnerability exists as when the uploaded file, exposed through a getter, through an Action is set to read-only, causing the subsequent actions on the file to give an error...

Remote Code Execution (RCE)

struts2-core is vulnerable to remote code execution RCE. The vulnerability exists through the possibility of a forced double OGNL expression through the $itemValue expression in simple/radiomap.ftl...

Directory Traversal

struts2-core is vulnerable to directory traversal attacks. The vulnerability exists due to the lack of sanitization in file path, allowing ..%252f to be used in the file path to perform directory traversal attacks...
