CVE-2022-40705: Apache SOAP: XML External Entity Injection (XXE) allows unauthenticated users to read arbitrary files via HTTP

[Arnout Engelen <engelen () apache org>]

Severity: important

Description:

** UNSUPPORTED WHEN ASSIGNED ** An Improper Restriction of XML External Entity Reference vulnerability in 
RPCRouterServlet of Apache SOAP allows an attacker to read arbitrary files over HTTP. This issue affects Apache SOAP 
version 2.2 and later versions. It is unknown whether previous versions are also affected.  NOTE: This vulnerability 
only affects products that are no longer supported by the maintainer.

Mitigation:

We do not expect to release a version that fixes this problem. Instead, we recommend users to migrate to one of the 
other actively maintained web service stacks such as Apache CXF (https://cxf.apache.org) or Apache Axis 
(https://axis.apache.org).

Apache SOAP is an archived project, with the last release published in 2003. This means it is no longer maintained, 
does not receive updates, and we do not commit to publishing CVE's for security problems in this project. This advisory 
is published purely as a courtesy.
