Apache Struts 2.3.x < 2.3.33 Denial of Service (S2-049)
Medium Nessus Plugin ID 118731
SynopsisA web application running on the remote host uses a Java framework
that is affected by multiple denial of service vulnerabilities.
DescriptionThe version of Apache Struts running on the remote host is 2.3.x prior
to 2.3.33. It is, therefore, affected by the following vulnerability:
- A flaw exists in unspecified Spring AOP functionality
that is used to secure Struts actions. An authenticated,
remote attacker can exploit this to cause a denial of
service condition. (CVE-2017-9787)
Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.
SolutionUpgrade to Apache Struts version 2.3.33 or later.
Alternatively, apply the workaround referenced in the vendor advisory.
