It was discovered that under certain conditions RESTEasy could be forced to parse a request with YamlProvider, resulting in unmarshalling of potentially untrusted data. An attacker could possibly use this flaw execute arbitrary code with the permissions of the application using RESTEasy.
It was found that GZIPInterceptor is enabled when not necessarily required in RESTEasy. An attacker could use this flaw to launch a Denial of Service attack.
A vulnerability was found in RESTEasy, where RootNode incorrectly caches routes. This issue results in hash flooding, leading to slower requests with higher CPU time spent searching and adding the entry. This flaw allows an attacker to cause a denial of service.
A flaw was found in all resteasy 3.x.x versions prior to 3.12.0.Final and all resteasy 4.x.x versions prior to 4.6.0.Final, where an improper input validation results in returning an illegal header that integrates into the server's response. This flaw may result in an injection, which leads to unexpected behavior when the HTTP response is constructed.
A cross-site scripting (XSS) flaw was found in RESTEasy in versions before 3.11.1.Final and before 4.5.3.Final, where it did not properly handle URL encoding when the RESTEASY003870 exception occurs. An attacker could use this flaw to launch a reflected XSS attack.
A cross-site scripting (XSS) flaw was found in RESTEasy, where it did not properly handle URL encoding when calling @javax.ws.rs.PathParam without any @Produces MediaType. An attacker could use this flaw to launch a reflected XSS attack.
Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-2c6g-pfx3-w7h8. This link is maintained to preserve external references.
Original Description In RESTEasy the insecure File.createTempFile() is used in the DataSourceProvider, FileProvider and Mime4JWorkaround classes which creates temp files with insecure permissions that could be read by a local user.
A flaw was found in RESTEasy client in all versions of RESTEasy up to 4.5.6.Final. It may allow client users to obtain the server's potentially sensitive information in headers, cookies and body when the server got WebApplicationException from the RESTEasy client call.
A flaw was found in RESTEasy in all versions of RESTEasy up to 4.6.0.Final. The endpoint class and method names are returned as part of the exception response when RESTEasy cannot convert one of the request URI path or query values to the matching JAX-RS resource method's parameter value. The highest threat from this vulnerability is to data confidentiality.
