CVE-2025-2905

An XML External Entity (XXE) vulnerability in Multiple WSO2 Products

Published May 5, 2025 CVSS 3.1 · 9.1 Critical EPSS 1.3% KEV · Not listed

Description

Due to the improper configuration of XML parser, user-supplied XML is parsed without applying sufficient restrictions, enabling XML External Entity (XXE) resolution in multiple WSO2 Products.

A successful XXE attack could allow a remote, unauthenticated attacker to:
* Read sensitive files from the server’s filesystem.
* Perform denial-of-service (DoS) attacks, which can render the affected service unavailable.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Type	Values Removed	Values Added
Description	An XML External Entity (XXE) vulnerability exists in the gateway component of WSO2 API Manager due to insufficient validation of XML input in crafted URL paths. User-supplied XML is parsed without appropriate restrictions, enabling external entity resolution. This vulnerability can be exploited by an unauthenticated remote attacker to read files from the server’s filesystem or perform denial-of-service (DoS) attacks. * On systems running JDK 7 or early JDK 8, full file contents may be exposed. * On later versions of JDK 8 and newer, only the first line of a file may be read, due to improvements in XML parser behavior. * DoS attacks such as "Billion Laughs" payloads can cause service disruption.
