Severity
7.5 (High) - CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
XML external entity (XXE) vulnerability in the XACML flow feature in WSO2 Identity Server 5.1.0 before WSO2-CARBON-PATCH-4.4.0-0231 allows remote authenticated users with access to XACML features to read arbitrary files, cause a denial of service, conduct server-side request forgery (SSRF) attacks, or have unspecified other impact via a crafted XACML request to entitlement/eval-policy-submit.jsp. NOTE: this issue can be combined with CVE-2016-4311 to exploit the vulnerability without credentials.
