CVE-2025-53621— DSpace 代码问题漏洞

DSpace vulnerable to XML External Entity (XXE) injection in import via Simple Archive Format (SAF) or import from external sources

DSpace open source software is a repository application which provides durable access to digital resources. Two related XML External Entity (XXE) injection possibilities impact all versions of DSpace prior to 7.6.4, 8.2, and 9.1. External entities are not disabled when parsing XML files during import of an archive (in Simple Archive Format), either from command-line (`./dspace import` command) or from the "Batch Import (Zip)" user interface feature. External entities are also not explicitly disabled when parsing XML responses from some upstream services (ArXiv, Crossref, OpenAIRE, Creative Commons) used in import from external sources via the user interface or REST API. An XXE injection in these files may result in a connection being made to an attacker's site or a local path readable by the Tomcat user, with content potentially being injected into a metadata field. In the latter case, this may result in sensitive content disclosure, including retrieving arbitrary files or configurations from the server where DSpace is running. The Simple Archive Format (SAF) importer / Batch Import (Zip) is only usable by site administrators (from user interface / REST API) or system administrators (from command-line). Therefore, to exploit this vulnerability, the malicious payload would have to be provided by an attacker and trusted by an administrator, who would trigger the import. The fix is included in DSpace 7.6.4, 8.2, and 9.1. Please upgrade to one of these versions. For those who cannot upgrade immediately, it is possible to manually patch the DSpace backend. One may also apply some best practices, though the protection provided is not as complete as upgrading. Administrators must carefully inspect any SAF archives (they did not construct themselves) before importing. As necessary, affected external services can be disabled to mitigate the ability for payloads to be delivered via external service APIs.

XML外部实体引用的不恰当限制(XXE)

DSpace 代码问题漏洞

DSpace是DuraSpace社区的一个开源的交钥匙存储库应用程序。 DSpace 7.6.4之前版本、8.2之前版本和9.1之前版本存在代码问题漏洞，该漏洞源于XML外部实体注入，可能导致敏感信息泄露。
