AI description
CVE-2017-5638 is a remote code execution (RCE) vulnerability found in Apache Struts 2, specifically within its Jakarta Multipart parser. This flaw arises from incorrect exception handling and error message generation during file upload attempts. Attackers can exploit this by crafting a malicious `Content-Type` HTTP header. The vulnerability occurs because the `Content-Type` value is not properly escaped after an error, and the `LocalizedTextUtil.findText` function, which constructs error messages, interprets content within `${...}` as an Object Graph Navigation Library (OGNL) expression. This allows for the evaluation of arbitrary OGNL expressions, leading to the execution of commands on the server. Affected versions include Apache Struts 2.3.x before 2.3.32 and 2.5.x before 2.5.10.1.
- Description
- The Jakarta Multipart parser in Apache Struts 2 2.3.x before 2.3.32 and 2.5.x before 2.5.10.1 has incorrect exception handling and error-message generation during file-upload attempts, which allows remote attackers to execute arbitrary commands via a crafted Content-Type, Content-Disposition, or Content-Length HTTP header, as exploited in the wild in March 2017 with a Content-Type header containing a #cmd= string.
